Japan’s castles are not only breathtakingly beautiful but also deeply rooted in the country’s rich history. These structures, many of which date back to the feudal era, tell stories of samurai warriors, powerful lords, and the ever-changing political landscape. For history enthusiasts, visiting these castles offers a rare glimpse into Japan’s past, from the warring states period to the rise of the Tokugawa shogunate. In this post, we’ll highlight some of the most iconic and must-see castles in Japan, each brimming with historical significance and architectural beauty.
1. Himeji Castle: The Pinnacle of Japanese Castle Architecture
Himeji Castle, located in Hyogo Prefecture, is often regarded as Japan’s most stunning and best-preserved castle. Known as the “White Heron Castle” due to its graceful appearance, Himeji Castle is an excellent example of feudal Japanese architecture. Constructed in the 14th century and expanded over the years, it became a strategic fortress during the warring states period.
Its most notable feature is its complex defensive system, including multiple gates, watchtowers, and a maze-like layout designed to confuse invaders. Himeji Castle’s beauty and its historical importance earned it a spot on UNESCO’s World Heritage list in 1993, making it a must-visit for history buffs and architecture lovers alike.
2. Osaka Castle: A Symbol of Power and Ambition
Osaka Castle, built by the warlord Toyotomi Hideyoshi in the late 1500s, played a significant role in Japan’s unification. This grand castle sits at the heart of Osaka city and has a rich history tied to the Sengoku period. The castle’s impressive five-story main keep once symbolized Hideyoshi’s aspirations to become the ruler of Japan.
Although the castle was destroyed and rebuilt several times, its iconic design remains a symbol of both the power and ambition that defined the era. Today, Osaka Castle’s park, museums, and surrounding gardens make it an excellent spot for visitors to delve into the country’s feudal history.
3. Nagoya Castle: A Blend of Tradition and Modernity
Nagoya Castle, located in Aichi Prefecture, is another significant historical site that every history enthusiast should visit. Originally built in 1612 by Tokugawa Ieyasu, the founder of the Tokugawa shogunate, Nagoya Castle played a key role in the political stability of the Tokugawa era.
The castle features traditional Japanese architecture, including golden shachihoko (dolphin-shaped roof ornaments), and boasts a beautiful surrounding park. Although much of the original structure was destroyed during World War II, the current reconstruction preserves much of the grandeur of the original. Visitors can learn about the history of the castle through exhibits and displays inside the castle’s museum.
4. Matsumoto Castle: A Stunning Example of a Black Castle
Matsumoto Castle, located in Nagano Prefecture, is one of Japan’s oldest surviving castles and one of the few to retain its original wooden interior. Known as the “Crow Castle” because of its dark exterior, Matsumoto Castle dates back to the late 1500s and is an excellent example of Japanese “hirajiro” (flatland castles), which were built without the usual hilltop placement.
The castle is unique for its black and white contrasting color scheme, which adds to its striking appearance. Inside, visitors can explore the original wooden beams and learn about the castle’s military role during the feudal era. Matsumoto Castle is also famous for its breathtaking view during cherry blossom season, making it a popular destination for both history and nature lovers.

5. Kumamoto Castle: The Stronghold of the Shimazu Clan
Located in Kumamoto City, Kumamoto Castle is one of Japan’s most impressive and historically significant castles. Built in the early 1600s, Kumamoto Castle is known for its size, grandeur, and defensive features, including massive stone walls, watchtowers, and deep moats. The castle was the stronghold of the powerful Shimazu clan during the Edo period and played a significant role in various military campaigns.
Despite suffering extensive damage during the 2016 earthquake, efforts are underway to restore Kumamoto Castle to its former glory. It remains a must-visit for anyone interested in the military history of Japan and the strategic importance of castles during the Edo period.
6. Nijo Castle: A Royal Residence with Cultural Significance
Nijo Castle, located in Kyoto, is unique for its role as a residence rather than a military fortress. Built in 1603 as the home of Tokugawa Ieyasu, the founder of the Tokugawa shogunate, Nijo Castle is a perfect blend of defense and elegance. The castle is renowned for its “nightingale floors,” which chirp when stepped on to alert its residents of intruders, and its beautiful gardens that reflect the sophistication of the era.
Designated as a UNESCO World Heritage site, Nijo Castle holds great cultural significance and offers a glimpse into the lifestyle of the Tokugawa shoguns. Visitors can explore the beautifully decorated rooms, lavish gardens, and learn about the political and social systems of feudal Japan.
7. Gifu Castle: The Strategic Castle on Mount Kinka
Gifu Castle, perched atop Mount Kinka, offers visitors not only a rich historical experience but also breathtaking views of the surrounding landscape. The castle is famously associated with the warlord Oda Nobunaga, one of Japan’s most influential figures, who used the castle as a base during his campaign to unify Japan.
Although the current structure is a reconstruction, it still maintains the strategic layout of the original, including its elevated position that provided military advantages. Gifu Castle is accessible via a cable car and offers historical exhibits and panoramic views of Gifu City below.
