Historic Sites, Places of Scenic Beauty, and Natural Monuments of Saga

Located in Kanzaki City, Saga Prefecture, the Anegawa Castle Ruins (Anegawa-jō Ato) are the remains of a late-medieval castle designated a National Historic Site in 2010. Defended not by stone walls but by a net-like network of waterways that divide the site into multiple inhabited islands, this rare moated-village castle is considered one of the largest and best-preserved examples of its kind in Japan. Founded in 1360 by Kikuchi Takeyasu and held for generations by his descendants the Anegawa clan, the site is also said to have served as a model for the later Saga Castle.
