What Is Kumamoto Castle? A Famous Fortress Ranked Among Japan’s Top Three Castles
Kumamoto Castle (Kumamoto-jō) is a renowned castle located in Chūō Ward, Kumamoto City, Kumamoto Prefecture, and is widely known as one of Japan’s top three castles.
Construction began in Keichō 6 (1601) under the master castle builder Katō Kiyomasa (Katō Kiyomasa) and was completed in Keichō 12 (1607), spanning the Azuchi–Momoyama period through the early Edo period.
It is also known by the nickname “Ginnan-jō” (Ginkgo Castle).
The castle grounds are vast, with a perimeter of about 5.3 km and a total area of about 98 hectares.
The 2016 Kumamoto earthquakes caused severe damage, including collapsed stone walls and destroyed buildings.
Restoration of the main keep has progressed, and visitors can enjoy exhibitions and panoramic views from the top floor.
The ruins are designated as a Special Historic Site of Japan.
It continues to attract many travelers as a symbol of recovery and resilience.

Kumamoto Castle Highlights: Top Things to See
1. The Majestic Main Keep and the “Musha-gaeshi” Stone Walls
Kumamoto Castle’s main keep consists of two towers—the larger and smaller keeps—welcoming visitors with an imposing presence.
Inside the keep, you can learn about the castle’s history—from its construction to its loss in the Satsuma Rebellion, its reconstruction in Shōwa 35 (1960), and its restoration after the Kumamoto earthquakes—through models and videos.
The top-floor observation level offers sweeping views over Kumamoto City.
On clear days, you may even be able to see as far as the Aso mountains.
The distinctive curved stone walls known as “Musha-gaeshi” (“warrior-repelling”) are also a highlight: gentle at the base and increasingly steep toward the top, their shape is known as a defensive design that helped prevent enemies from climbing in.
2. Katō Kiyomasa’s Castle-Building Techniques
Katō Kiyomasa, the castle’s builder, incorporated practical fortification know-how throughout the complex.
You can observe features such as civil engineering works that drew the Tsuboi River to use as a moat, stone walls built with stones of many sizes, and strategically placed turrets (yagura) and gates that reveal the structure of the castle.
It is said that at the time of construction, the fortress complex included 3 main keeps, 49 turrets, 18 turret gates, and 29 castle gates.
3. Kumamoto Castle as a Symbol of Recovery
The 2016 Kumamoto earthquakes caused extensive damage, including major stone-wall collapses.
Restoration work is being carried out in phases.
