A hilltop castle in central Kumamoto, counted among Japan's three premier castles with Himeji and Matsumoto. Its origins go back to 1467; Katō Kiyomasa expanded it between 1601 and 1607 into a vast complex of 49 turrets, 18 turret gates and 29 smaller gates, about 1.6 kilometres from east to west. It is famous for its curving musha-gaeshi stone walls, which grow steeper toward the top until they cannot be climbed. Besieged in 1877 during the Satsuma Rebellion, it lost its main keep to fire; the keep was rebuilt in concrete in 1960 at 30.3 metres, and 13 original structures survive as Important Cultural Properties. The 2016 earthquake badly damaged the castle; the main keep was restored and reopened, and work on the whole complex runs to around 2052. Then a strong earthquake struck Kumamoto on 28 July 2026, collapsing stone walls in about forty places; the castle reopened to visitors on 13 August 2026, and some routes may stay closed during repairs. Tickets are 800 yen, and it opens 9:00-17:00, according to its official site. The entrance is near Kumamotojō-Shiyakusho-mae tram stop; check which routes are open before you go.
