Yatsushiro
Yatsushiro lies around the lower Kuma River in Higo. Its castle moved over time from the hills to Mugishima at the river mouth, where Konishi Yukinaga established a new stronghold. After the Hosokawa received Higo in 1632, their retainers of the Matsui family eventually took charge of Yatsushiro Castle. From the mid-seventeenth century, reclamation promoted by the Hosokawa and Matsui extended the western plain into the tidal flats.
