Shimabara Castle

Shimabara Castle (島原城, Shimabarajō) is a striking white-walled fortress built during the Edo Period as the centerpiece of the feudal domain. Its construction was so extravagant that it sparked unrest, contributing to the Shimabara Rebellion (1637-1638). Though destroyed in the Meiji Period, the castle was rebuilt in 1964 and now houses the Castle Tower Museum, displaying Christian artifacts, samurai armor, and weapons. From its observation deck, visitors can enjoy stunning views of Mount Unzen and, on clear days, Kumamoto.

Surrounding the castle are attractions like the Seibo Memorial Hall, showcasing works of sculptor Kitamura Seibo, and the Teppo-machi Samurai District with preserved samurai houses. Don’t miss the City of Swimming Carp, where vibrant koi swim through serene canals fed by Mount Unzen’s spring water. Shimabara offers a rich blend of history, art, and natural beauty, making it a must-visit destination.
