In 1619, Mugishima Castle collapsed due to a large earthquake then Katō Kiyomasa's son Kato Tadahiro ordered his vassal Katō Masataka to build a new castle.[2] In 1632, Hosokawa Tadaoki entered the castle by the Tokugawa shogunate's order and spent retired life in the kitanomaru compound of the castle.[3] The castle is now only ruins, just some remnants of water moats and stone walls. Yatsushiro Castle was registered as a National Historic Site in 2014 as one of the Remains of Yatsushiro Castles, combining both Furufumoto Castle and Mugishima Castle.[4] Yatsushiro castle was listed as one of the Continued Top 100 Japanese Castles in 2017.[5]
