Perched on a hill at an altitude of approximately 88 meters on the south bank of the Kiso River in Inuyama City, Aichi Prefecture, Inuyama Castle is a National Treasure of Japan. It is celebrated as one of the oldest surviving castle keeps (tenshu) in the country, continuing to captivate visitors with its elegant and historic presence. It is a famous spot for viewing the majestic flow of the Kiso River, allowing visitors to experience the essence of Japanese castle architecture alongside the changing beauty of the four seasons.
The history of Inuyama Castle dates back to the Tenbun era (around 1537), when it was constructed by Nobuyasu Oda, the uncle of the famous warlord Oda Nobunaga. Due to its strategic location along the Kiso River, it developed as a vital hub for logistics and politics along the Nakasendo and Kiso Kaido routes. Over the centuries, the castle was ruled by various powerful figures, including Ikeda Tsurumasa and Ishikawa Sadakiyo under the Toyotomi regime. During the Edo period, the Naruse clan, high-ranking vassals of the Owari Tokugawa family, served as the lords of the castle, and the current keep was refined during their rule. Although the site faced challenges during the Meiji era when many structures were demolished, it is now carefully preserved and managed by the Inuyama Castle Hakutei Bunko Foundation.

The greatest attraction is undoubtedly the original castle keep. While the interior space is quite limited, the view of the vast Kiso River from the top is truly overwhelming. The very structure of the castle serves as a living historical document, illustrating its former role as a defensive stronghold during the Sengoku (Warring States) period. Climbing the stairs to the top is a unique experience, as the steep and narrow passages offer a firsthand look at the architectural techniques and defensive designs of the era.
Inuyama Castle reveals a different face with every season. In spring, the surrounding area is adorned with beautiful cherry blossoms, while in autumn, the vibrant foliage colors the landscape against the Kiso River. A particularly magical way to visit is during the evening; the castle is illuminated from sunset until 22:00, creating a mystical silhouette against the dark sky. Whether you prefer exploring the historical structures in bright daylight or admiring the ethereal night illumination, there is a unique charm to every visit.

Climbing the castle keep is a quintessential experience for anyone wishing to understand Japanese castle culture. The interior provides a rare opportunity to feel the historical architectural style directly. Beyond the castle, exploring the surrounding castle town is a highlight of any trip. There are many areas that retain a historic atmosphere, and using a set pass (tourist ticket) that includes nearby facilities can make your sightseeing experience even more rewarding.
