Osaka Castle Toyotomi Stone Wall Museum

Exhibition Overview

The Osaka Castle Toyotomi Stone Wall Museum is dedicated to showcasing the original stone walls of Osaka Castle built by Toyotomi Hideyoshi, officially opening on April 1, 2025. Located southeast of Osaka Castle Tower, this underground exhibition hall allows visitors to closely observe the Toyotomi-era stone walls buried for about 400 years, experiencing their historical charm and architectural beauty. The museum consists of two levels: the upper level features a guidance room and a theater, introducing the discovery process of the stone walls and the different appearances of Osaka Castle during the Toyotomi and Tokugawa periods through images and text; the underground exhibition hall displays the actual stone wall remains, guiding visitors through time to experience a pivotal moment in Japan's Warring States period. This is not only a feast for the eyes and knowledge but also an excellent opportunity to explore the deep historical roots of Osaka Castle.

Historical Background

Toyotomi Hideyoshi began constructing Osaka Castle in 1583 as the base for his unification of Japan. This castle, renowned as "unmatched in the three countries," is famous for its luxurious grandeur and strong defenses. The "Tsukinomaru" area within the castle served as the private living space for Hideyoshi and his family, making it the core of the castle. However, in the summer campaign of 1615, the Toyotomi clan was defeated by the Tokugawa shogunate, leading to the destruction of the original Osaka Castle. To erase the influence of the Toyotomi clan, the Tokugawa shogunate buried its stone walls underground and built a new Tokugawa Osaka Castle on top. The Toyotomi-era stone walls remained buried for centuries until they were rediscovered during archaeological excavations in 1984. These stone walls still bear scorch marks from the summer campaign of Osaka, witnessing the intensity of war and the changes of the era. Starting in 2013, the city of Osaka launched the "Toyotomi Stone Wall Public Project," and after 12 years of effort, this exhibition hall will finally be completed in 2025, allowing the world to glimpse this buried history.

Cultural Significance

The stone walls were constructed using the "wild surface" technique, with stones left unrefined, showcasing a rugged yet solid aesthetic that reflects the practicality and power symbolism of the Warring States period. These stone walls are not only architectural remnants but also witnesses to the rise and fall of the Toyotomi clan, narrating Japan's historical transition from chaos to unification. The exhibition hall presents this history in a vivid manner through modern technology and archaeological findings, allowing visitors to feel the unique charm of Osaka as a cultural center of Japan while viewing the stone walls. Additionally, the citizen-funded plaque inside the museum highlights the enthusiasm of Osaka's citizens for cultural preservation, embodying the important role of "the people" in historical conservation.

Attraction Introduction

Ikutama Shrine, located within Osaka Castle Park, is a small shrine hidden in the shadow of the historic castle, yet it carries profound historical and cultural significance. Situated south of the Tamatsukuri Gate of Osaka Castle, the shrine is surrounded by lush trees and ancient stone walls, evoking tales of past battles and peace. Although modest in size, its unique

Historical Background

Historical Background

Ikutama Shrine was established in the first year of the Meiji era (1868) to commemorate the soldiers of the shogunate who committed suicide within Osaka Castle during the Boshin War. At that time, Osaka Castle was engulfed in flames due to the conflict, and many shogunate soldiers chose to stay and die rather than flee. The Satsuma and Choshu clans funded the construction of this shrine to honor the loyalty of these soldiers, naming it "Ikutama Shrine." The term "Ikutama" symbolizes good fortune and peace, expressing mourning for the war's deceased and a wish for peace. The area where the shrine stands is believed to be the site of the Ishiyama Hongan-ji, an important base for the Jodo Shinshu sect during the Warring States period, later chosen by Toyotomi Hideyoshi as the site for the castle, forming the foundation of present-day Osaka Castle. This layering of history makes the shrine not only a memorial but also a microcosm of Japan's transitions between war and peace.

Cultural Significance

The existence of Ikutama Shrine reminds people how the sites of war can transform into symbols of peace, resonating with the Japanese traditional spirit of "wa" (harmony). Despite its small scale, the stories behind it intertwine with the history of Osaka Castle, one of Japan's three great castles, showcasing the diverse aspects of Japanese history from the turmoil of the Warring States period, the religious struggles of Ishiyama Hongan-ji, to the transformations during the Bakumatsu period. Visitors can feel the respect for the deceased in Japanese culture during their visit, as well as the profound meaning of pursuing reconciliation and coexistence through historical changes. This shrine also attracts those interested in the history of the Bakumatsu period or war culture, allowing for reflection on the connections between the past and present in a serene environment.

Engraved Stone Plaza (Osaka Castle)

Admission Fee: Free

Attraction Overview

Engraved Stone Plaza, located within Osaka Castle Park, is an outdoor exhibition space rich in history, dedicated to showcasing the "engraved stones" marked by various feudal lords during the construction of Osaka Castle's stone walls. These engraved stones are part of the 400th anniversary celebration of Osaka Castle's construction (1983), established to help visitors gain a deeper understanding of the historical and cultural significance of the castle's stone walls. The plaza is situated north of the Osaka Castle keep, near Gokurakubashi, featuring stones engraved with family crests, symbols, or designs from various feudal lords, with thousands of stones sourced from restoration projects or excavated artifacts, exuding a strong historical atmosphere. Visitors can closely observe and even touch these engraved stones, feeling the traces left by ancient stonemasons and lords. Detailed information boards nearby explain the origins and significance of the engraved stones, transporting visitors back to the castle construction site during the Tokugawa era.

Historical Background

The construction of Osaka Castle's stone walls began during the Genna to Kan'ei periods (1620-1629), mobilized by the Tokugawa shogunate with the involvement of 69 feudal lords from western Japan. Each lord was assigned specific areas for the stone wall project, and to mark their contributions, they engraved their family crests, symbols, or names on the massive stones they transported, known as "engraved stones." These stones served not only as markers for project management but also as symbols of competition and honor among the lords. The existing stone walls of Osaka Castle were mostly built during the Tokugawa period, while many from the Toyotomi Hideyoshi era are buried underground (some are currently being excavated as part of the "Toyotomi Stone Wall Public Project"). Engraved Stone Plaza was established in 1983 to commemorate the 400th anniversary of Osaka Castle's construction, showcasing stones primarily sourced from restoration projects or excavated artifacts, becoming valuable historical materials for studying Osaka Castle's history and stone wall construction techniques.

Cultural Significance

Each engraved stone in Engraved Stone Plaza carries family crests and symbols that narrate the lords' pursuit of power and honor, as well as the exquisite craftsmanship of the stonemasons of the time. These stones witness the historical transitions of Osaka Castle from the glory of Toyotomi Hideyoshi to the reconstruction by the Tokugawa shogunate, reflecting the intricate organization and division of labor within Japan's feudal system. The area around the plaza, known as Yamari-maru, is said to have been a tea gathering place during the Toyotomi Hideyoshi era, where tea masters like Sen no Rikyū enjoyed tea ceremonies with Hideyoshi, adding cultural depth. Additionally, nearby stands the "Site of Toyotomi Hideyori and Yodo-dono's Seppuku" monument, reminding visitors of the tragic events of the Summer Siege of Osaka, enhancing the historical weight of the site. With its unique historical value and cultural significance, Engraved Stone Plaza is an unmissable attraction within Osaka Castle Park, allowing visitors to explore the context of Japanese history while appreciating the natural beauty.

Site of the Seppuku of Hideyori and Yodo-dono

Located within Osaka Castle Park, the "Site of the Seppuku of Hideyori and Yodo-dono" is a historical monument commemorating the tragic moment in 1615 when Toyotomi Hideyori, his mother Yodo-dono, and many retainers took their own lives here during the Summer Siege of Osaka. This monument, situated at a corner of Yamasato Maru, quietly narrates the rise and fall of the Toyotomi clan and the end of the Sengoku period in Japan.

• Attraction Overview

  The "Site of the Seppuku of Hideyori and Yodo-dono" monument is located in Yamasato Maru within Osaka Castle Park, just a few steps from the main keep, yet often overlooked by hurried visitors due to its hidden location. Established by the city of Osaka in 1997, this monument marks the historical site where Toyotomi Hideyori, Yodo-dono, and about 30 retainers committed seppuku during the Summer Siege of Osaka in 1615. Next to the monument is a stone plaza displaying the massive stones brought by various daimyos for the construction of Osaka Castle, with family crests carved into them, reflecting the glory and transience of the Sengoku period. The inscription is brief yet heavy, reminding every visitor that this land witnessed the end of an era. Although somewhat remote, its tranquility enhances its solemnity, often adorned with fresh flowers as a tribute to this tragic history.

  Historical Background

  On May 8, 1615 (lunar calendar), the Summer Siege of Osaka reached its final stage as the army led by Tokugawa Ieyasu breached Osaka Castle, engulfed in flames, threatening the last stronghold of the Toyotomi clan. Toyotomi Hideyori, the legitimate son of Toyotomi Hideyoshi, bore the family's hopes for revival from a young age but found himself powerless in this battle. His mother, Yodo-dono, the daughter of Oichi, sister of Oda Nobunaga, served as the spiritual support of the Toyotomi family, retreating with Hideyori to the Tang warehouse in Yamasato Maru (also said to be the Shusansho turret). They had hoped for salvation through Hideyori's wife, Chihime, the granddaughter of Tokugawa Ieyasu, but their plea was ultimately rejected. Faced with despair, Hideyori and Yodo-dono chose to set fire to themselves, along with loyal retainers such as Ohno Harunaga and Mouri Katsunaga, marking the complete downfall of the Toyotomi clan. This tragedy not only ended the legacy of the Sengoku period but also paved the way for the long-term rule of the Tokugawa shogunate.

  It is worth mentioning that there are various historical records regarding the location of the seppuku, with sources like "Sunpu-ki" mentioning the Ninomaru belt, and "Records of the Ii and Todo families" referring to the rice granary, but the Tang warehouse in Yamasato Maru is the most commonly accepted, which is why the city of Osaka chose to erect the monument here. In 1980, a skull of a male in his twenties was discovered at the site of the Ninomaru, believed to belong to Hideyori, and is now enshrined at Kiyomizu Temple in Kyoto, adding a layer of mystery to this history.

  Cultural Significance

  The "Site of the Seppuku of Hideyori and Yodo-dono" symbolizes the end of the Sengoku period in Japan. The story of Toyotomi Hideyori and Yodo-dono embodies profound themes of loyalty, family, and fate. Yodo-dono, one of the "Three Sisters of the Sengoku" (Chacha), is a figure of resilience and tragedy. She witnessed her mother Oichi and Shibata Katsuie commit seppuku at Kitashō Castle, a memory that may have influenced her final words to Chihime: "Live on, carry on the memory of the Toyotomi clan." This dedication to life and legacy reflects the Japanese cultural pursuit of "righteousness" and "name." Additionally, this site serves as a reminder of the countless families torn apart and sacrificed by war, calling for peace and reflection. The fresh flowers often seen at the monument are a gentle continuation of contemporary Japanese people's historical memory.

  For history enthusiasts, this is an excellent spot to explore the twilight of the Sengoku period. Standing quietly before the monument, one can almost hear the echoes of clashing swords and roaring flames, feeling the weight and desolation of Japan's historical turning point.

Osaka Castle Gokurakubashi

Attraction Overview

Gokurakubashi, located within Osaka Castle Park, is the only bridge leading to the main keep of Osaka Castle, spanning the inner moat and connecting the Yamazato-maru and Honmaru areas. Standing in the middle of the bridge, visitors can admire the majestic silhouette of the Osaka Castle tower, while the stone walls and moat on either side create a picturesque scene, making it a popular photography spot for countless tourists. Especially during the spring cherry blossom season, Gokurakubashi harmonizes beautifully with the surrounding cherry trees, becoming one of the most iconic views of Osaka Castle. The bridge is constructed of reinforced concrete, but the ends are adorned with wooden materials, blending traditional and modern aesthetics. From the bridge, one can also overlook the inner moat, where ducks can occasionally be seen swimming, adding a touch of natural charm.

Historical Background

The history of Gokurakubashi dates back to the origins of Osaka Castle, with its name derived from the site of the Ishiyama Hongan-ji temple. Ishiyama Hongan-ji was a Pure Land sect temple dedicated to Amida Buddha, and Gokurakubashi was thus named as a symbolic bridge to the "Pure Land." It is recorded that Toyotomi Hideyoshi constructed the original Gokurakubashi in 1596 (the first year of Keicho) as a corridor bridge between the northern and second baileys of Osaka Castle. This bridge was extravagantly designed, with Portuguese missionary Luis Frois describing it as having a wooden base adorned with lacquer, gold leaf, and precious stones, intricately carved, approximately 50 meters long, and dazzling in the sunlight, showcasing Hideyoshi's power and wealth. However, after Hideyoshi's death in 1598, the bridge was dismantled in 1600, with some components relocated to the Toyokuni Shrine in Kyoto, and later in 1602 to Hōgon-ji Temple on Chikubushima Island in Lake Biwa, where the existing national treasure, the karamon gate, remains, preserving the splendor of the Toyotomi era.

Subsequent to the reconstruction of Osaka Castle by the Tokugawa shogunate, Gokurakubashi was buried after the Summer Siege of Osaka (1615) and was burned during the Boshin War (1868). The current Gokurakubashi was built in 1965; although it is about 3 meters narrower than the Edo-period bridge, its location and function continue to uphold historical traditions, making it an important landmark of Osaka Castle. Wet plate photographs taken during the late Edo period captured Gokurakubashi along with the Yamazato Gate and Tamon Turret, providing valuable insights for the study of Osaka Castle's history.

Honmaru Japanese Garden

Overview

The Honmaru Japanese Garden, located in the core area of Osaka Castle Park, is a pond-style strolling garden that features the Osaka Castle keep as its backdrop. With its tranquil atmosphere and exquisite landscaping, the garden attracts countless visitors. At its center lies a crane-wing shaped pond covering about 300 tsubo, surrounded by lush trees, with the water reflecting the majestic keep. Especially during the autumn foliage season, the contrast of maple leaves and the castle creates a popular photo spot for enthusiasts.

The winding paths within the garden are perfect for leisurely strolls, allowing visitors to experience the beauty of the fusion between Osaka Castle's history and nature.

Historical Background

The Honmaru Japanese Garden was established in 1931 (Showa 6), concurrently with the restoration of the Osaka Castle keep, and was meticulously created by the city of Osaka. Originally designed as an annex garden to the Kishu Palace within the Honmaru, the Kishu Palace was a structure from Wakayama Castle's Ninomaru, relocated to Osaka Castle's Honmaru during the Meiji era, but unfortunately destroyed by fire in 1947 (Showa 22), leaving only the garden today. During the Edo period, the Honmaru served as the political center of Osaka Castle, housing the Honmaru Palace, which was the hub of the shogunate's governance, rather than the Kishu Palace or the Japanese garden. The garden's design draws inspiration from traditional Japanese landscaping techniques, with the central crane-wing pond complementing the background hill, showcasing a strong Japanese garden character.

During special open periods, visitors can explore its interior structure and experience the architectural craftsmanship and military defense wisdom of the Edo period.

• Attraction Overview

  Tamon Yagura is situated within the masugata of Otemon, connected to Chinkan Yagura and Otemon, creating an impregnable defense system. The yagura has a slender appearance, resembling a white castle wall, exuding grandeur. Its design is said to be inspired by the tamon castle of the Warring States general Matsunaga Nagahide, utilizing a longhouse format that allows soldiers to quickly assemble and attack invading enemies from above. The yagura features defensive installations such as "yoko-otoshi" and gun slots, allowing defenders to throw weapons or shoot from high vantage points, showcasing the military ingenuity of Edo period castle architecture. During special openings, visitors can enter the yagura and explore its spacious interior, including a central room of about 70 tatami mats and displayed historical materials, as if stepping back into the wartime scenes of the Edo period. The view from the yagura offers stunning landscapes of stone walls and earthen ramparts, especially beautiful during cherry blossom and maple leaf seasons, complementing the natural beauty of Osaka Castle Park.

  Historical Background

  Tamon Yagura was originally built by the Tokugawa shogunate in 1628 (the 5th year of Kan'ei) as part of the reconstruction of Osaka Castle. The castle, created by Toyotomi Hideyoshi in 1583, was destroyed in the Summer Siege of Osaka in 1615, prompting the Tokugawa shogunate to rebuild this magnificent fortress to solidify control over the western territories. Tamon Yagura, along with other structures, formed the core of the defense, protecting Otemon from enemy attacks. However, a lightning strike in 1783 (the 3rd year of Tenmei) caused a fire that destroyed Tamon Yagura, leaving only the stone walls. It wasn't until 1848 (the 1st year of Kaei) that the shogunate undertook major restoration work to rebuild the yagura, restoring its former glory. This reconstructed Tamon Yagura has withstood the turmoil of the late Edo period, the Meiji Restoration fire, and World War II air raids, remaining one of the most precious historical relics within Osaka Castle. The discovery of construction documents during restoration revealed names of buildings from that time, such as "Atemiguchi" and "Omon," recording the architectural culture and military terminology of the Edo period.

Osaka Castle Otemon Gate

Osaka Castle Otemon Gate is the main entrance to Osaka Castle and serves as the core access point to this famous Japanese castle. Known for its simple yet imposing appearance, this Korean-style gate carries a rich history and is an excellent starting point for exploring the history and culture of Osaka Castle.

The stone walls inside the gate rise to 3 meters and feature a "Musha Kake" design used to conceal soldiers in case of enemy attacks, fully demonstrating Osaka Castle's defensive capabilities as a military fortress. Following the path from Otemon Gate along the Tamon Turret and Sakura Gate, visitors will eventually reach the Main Tower of Osaka Castle, experiencing the ancient castle's charm and historical atmosphere along the way.

Historical Background

Osaka Castle was originally built by Toyotomi Hideyoshi in 1583 but was destroyed during the Winter and Summer Siege of Osaka (1614-1615). The existing Otemon Gate was constructed in 1628 (the 5th year of the Kan'ei era) and is an important remnant from the reconstruction of Osaka Castle by the Tokugawa shogunate. The Tokugawa shogunate spent ten years (1620-1630) on "Tenkahōrin," mobilizing various feudal lords to rebuild the castle, with Otemon Gate initially constructed under the supervision of Kato Tadahiro, the lord of Kumamoto in Higo, and later completed by Arima Toyoshi, the lord of Kurume in Chikugo. The main roof tiles and the Tokugawa family crest tiles on the gate highlight the authority of the Tokugawa shogunate. Otemon Gate has withstood fires during the late Edo period, air raids during World War II, and lightning strikes, remaining steadfast and was designated as an Important Cultural Property of Japan in 1953, along with the earthen walls on both sides. The unique "Nezuke" repair technique of its supporting pillars, especially the complex design of the right supporting pillar, is a marvel in Japanese architectural history. In 1983, an X-ray scan revealed the construction mystery, confirming that it was built by Ishihama Group, showcasing the superb skills of Edo-period craftsmen. During the Meiji era, Otemon Gate served as the main entrance to the Osaka Garrison (the Fourth Division Headquarters), witnessing Japan's modernization transformation.

During special opening periods, visitors can enter the turret to closely observe replicas of matchlock guns and historical relics, experiencing its grandeur as the core of Osaka Castle's defenses.

Historical Background

The history of Chikuan Yagura dates back to the time of Ishiyama Hongan-ji during the Warring States period. It is said that during the Ishiyama War from 1570 to 1580, when Oda Nobunaga attacked the Ishiyama Hongan-ji located here, soldiers lamented the formidable turret's defenses, exclaiming, "This turret is worth a thousand kan" (approximately 100 million yen today), hence the name "Chikuan Yagura." This turret was later rebuilt in Toyotomi Hideyoshi's Osaka Castle and was reconstructed again by the Tokugawa shogunate in 1620 after the Summer Siege of Osaka in 1615, becoming the existing Chikuan Yagura. The Tokugawa shogunate commissioned Kobori Enshu for the design, while the stone walls were constructed by Kato Tadahiro, the lord of Kumamoto Castle, with the family crest "Hebi no Me" still visible on the stone walls. During the dismantling and restoration in 1961, inscriptions were found on the wood stating "September 13, 6th year of Genna, the pillars were erected," confirming the construction date. Chikuan Yagura has withstood the Meiji Restoration fire and World War II air raids, remaining steadfast and designated as an Important Cultural Property of Japan in 1953.

Historical Background

The "Nishinomaru" area where Nishinomaru Garden is located was an important site second only to the main castle during the Toyotomi era. Historical records indicate that this was the residence of Toyotomi Hideyoshi's wife, Nene, who held a prominent position. Hideyoshi's brother, Hidenaga, also had a residence here. Later, Tokugawa Ieyasu took residence in Nishinomaru before the Battle of Sekigahara and built another castle tower here, which sparked controversy and became one of the triggers for the battle. After the Edo period, Nishinomaru served as a defensive site for Osaka Castle, housing the gunpowder storehouse "Gunpowder Storehouse," which remains well-preserved and is now an important cultural property. In 1965, Nishinomaru Garden was opened to the public as a lawn garden, becoming an integral part of Osaka Castle Park, carrying historical memories from the Warring States period to modern times.

Inuiyagura - An Important Cultural Asset of Osaka Castle

Attraction Introduction

Inuiyagura (いぬいやぐら) is located at the northwest corner of Nishi no Maru Garden in Osaka Castle, and is one of the oldest existing structures of Osaka Castle, built in 1620 (the 6th year of Genna). It is designated as an Important Cultural Property of Japan. This turret is known for its unique L-shaped structure and "Sōnikai-zukuri" (first and second floors of equal area), showcasing the exquisite craftsmanship of early Edo period castle architecture. Inuiyagura sits beside the outer moat, offering a 230-degree wide view, allowing surveillance from Otemon to Kyobashi, serving both defensive and lookout purposes. The turret retains original chōna marks, demonstrating the skills of the craftsmen of the time, while the hidden arrow slits highlight its function as a military defense facility. Visitors can admire the majestic appearance of this historical building up close from within Nishi no Maru Garden, experiencing the grandeur of Osaka Castle as a stronghold of the Tokugawa shogunate in the western region.

Historical Background

The history of Inuiyagura dates back to the "Tenka Fushin" period when the Tokugawa shogunate rebuilt Osaka Castle. After the Summer Siege of Osaka in 1615, the Toyotomi's Osaka Castle was destroyed, and Tokugawa Hidetada ordered its reconstruction, starting the project in 1620, designed by the renowned architect Kobori Enshū. Inuiyagura, along with Senkan-yagura, was among the first buildings completed at that time, witnessing the Tokugawa shogunate's control over the western region. The ridge tiles of the turret are inscribed with "Genna 6th year, 9th month, auspicious day, made by Fukakusa Sakujirō," confirming its construction date. In the late Edo period, Inuiyagura underwent major repairs due to foundation subsidence, and was further restored by the army during the Meiji period. During the 1945 air raid on Osaka, the northern side of Inuiyagura was hit by a bomb, causing some stone damage, and a major restoration in 1956 restored its Edo period appearance. The stone walls of Inuiyagura were overseen by Hosokawa Tadaoki, with some granite sourced from his Kokura domain, adding local character.

Cultural Significance

The name "Inui" is derived from the northwest direction (Inu and I), reflecting the application of ancient directional studies and feng shui concepts in castle design. The L-shaped structure and Sōnikai-zukuri design reflect the early Edo period's pursuit of balance between military and aesthetics. The chōna marks and hidden arrow slits within the turret tell the tense atmosphere of wartime, while its resilience through multiple restorations symbolizes the Japanese cultural value placed on historical heritage. During the special opening period, visitors can enter the turret to glimpse the architectural details of the Edo period, experiencing the profound historical significance of Osaka Castle as a turning point in Japanese history. Inuiyagura, along with other important cultural assets of Osaka Castle, outlines the historical transitions from Toyotomi to Tokugawa, and into modern times, attracting countless history enthusiasts and tourists.

Osaka Castle Gunpowder Storehouse

Admission Price: Nishinomaru Garden entrance fee: Adults ¥200, free for elementary and junior high school students (free access to the exterior of the storehouse; interior is free during special openings)

Attraction Introduction

The Osaka Castle Gunpowder Storehouse (えんしょうぐら) is located within the Nishinomaru Garden of Osaka Castle Park and is a valuable stone gunpowder storehouse dating back to the Edo period. "Gunpowder" refers to black powder, and this building was specifically constructed for storing gunpowder. It is the only structure among the ten important cultural properties of Osaka Castle that requires entry into the Nishinomaru Garden (a paid area) for viewing. Its unique stone structure and thick granite walls exude a strong historical atmosphere, attracting countless visitors.

The exterior of the storehouse is understated yet sturdy, featuring a rectangular stone structure topped with a tiled roof, which displays the Tokugawa shogunate's "Aoi crest," reflecting its historical context. Although the interior is usually not open to the public, it can be visited during specific periods (such as special open events), where the intricate connections of the beams and stones inside are truly impressive. Standing in front of the storehouse, visitors can almost feel the grandeur of Osaka Castle as a military stronghold in western Japan during the Edo period.

Historical Background

The Gunpowder Storehouse was built in the second year of the Jōkyō era (1685) under the supervision of the then Osaka Castle governor, Tsuchiya Masanari. During the Tokugawa shogunate, Osaka Castle served as a military base in western Japan, storing large quantities of gunpowder, weapons, and food, making the safety of the gunpowder storehouse particularly crucial. As early as the third year of Manji (1660), another earthen gunpowder storehouse located at Aoyakuchi was struck by lightning, causing a massive explosion that resulted in numerous casualties both inside and outside the castle, damaging over 1,400 nearby homes, with legends claiming that debris from the castle gate flew as far as 14 kilometers away to the Anotoge. This tragedy prompted the shogunate to resolve to build a safer gunpowder storehouse.

To prevent similar incidents from occurring, the existing Gunpowder Storehouse was designed entirely of stone, with walls 2.4 meters thick, and the floor, ceiling, and beams constructed of granite, with the stone joints filled with plaster and a thick layer of earth on the roof to enhance waterproofing and fire resistance. This all-stone gunpowder storehouse is extremely rare in Japan and is considered a treasure in architectural history. The storehouse was designated as an Important Cultural Property of Japan in the 28th year of Shōwa (1953) and underwent dismantling and restoration in the 35th year of Shōwa (1960), restoring its original appearance, and it remains in good condition to this day.

Higo Stone (Osaka Castle)

Attraction Introduction

Higo Stone is located at the Kyobashi entrance of Osaka Castle Park, and is the second largest stone in terms of surface area within Osaka Castle, following the famous Tako Stone. This massive stone measures approximately 11 meters wide and 5.1 meters high, with a surface area of 54.17 square meters, equivalent to 33 tatami mats. Its grandeur is truly breathtaking. Higo Stone showcases the pinnacle of Japanese castle construction techniques from the early 17th century, with its flat surface and exquisite stone stacking craftsmanship. As you enter through the Kyobashi entrance, the giant stone stands tall above the stone walls, accompanied by an information board detailing its background and features, allowing visitors to easily recognize and appreciate its historical significance. Compared to the popular Sakuramon entrance, the Kyobashi entrance sees fewer visitors, making it ideal for quietly admiring the stone's magnificence and artistry.

Historical Background

Osaka Castle was initiated by Toyotomi Hideyoshi in 1583 to showcase his ambition to unify Japan. After the Summer Siege of Osaka in 1615, the Toyotomi clan fell, and the Tokugawa shogunate rebuilt Osaka Castle in the early 17th century, during which Higo Stone was used for the stone walls. The name Higo Stone is derived from a legend that it was brought by Kato Kiyomasa, the lord of Higo (present-day Kumamoto), but historical evidence shows that this stone was actually transported by Ikeda Tadao of Bizen Okayama Domain, sourced from granite quarries on islands like Shodoshima or Inujima in the Seto Inland Sea. At that time, the Tokugawa shogunate mobilized 64 daimyos from western Japan to share the stone wall project, with each daimyo competing to transport massive stones to demonstrate their power and loyalty, making Higo Stone one of the masterpieces of this "giant stone competition." The engraved stones visible on the stone walls bear the family crests of the daimyos, telling the political and technical stories of the castle's construction.

Cultural Significance

The transportation and stacking techniques of the giant stones reflect the exquisite craftsmanship of ancient Japanese civil engineering, especially the granite that traveled from the Seto Inland Sea, showcasing the remarkable collaboration of water transport and human effort. The Kyobashi entrance, where Higo Stone is located, along with other giant stones like Tako Stone and Furisode Stone, forms a cultural landscape of Osaka Castle, attracting history enthusiasts and tourists eager to explore the deep roots of Japanese castle culture. Standing before Higo Stone, one can almost hear the ambitions of the daimyos and the sweat of the craftsmen from 400 years ago, feeling the tranquil power of this giant stone transcending time.

Historical Background

Osaka Castle was built by the Warring States lord Toyotomi Hideyoshi in 1583 as a base for unifying Japan, symbolizing his power and ambition. The design of the boat is inspired by the "Toyotomi Period Osaka Folding Screen" (currently housed in Eggenberg Palace, Austria), which depicts Hideyoshi's luxurious "Phoenix Boat." This boat was a symbol of Hideyoshi's love for luxury and gold. After the Summer Siege of Osaka in 1615, the Toyotomi regime fell, and the Tokugawa shogunate rebuilt Osaka Castle, making the inner moat and stone walls the core of its defenses. In 2015, to commemorate the 400th anniversary of the Siege of Osaka, the boat began daily operations, aiming to recreate the past glory and pay tribute to the history of the Toyotomi era and the fallen warriors. The gold leaf design on the boat is not only a visual feast but also carries memories of the Warring States period.
