The castle was located on an important path for travelers on a road which met what was the main path and the Ose-gawa River crossing from the east until the Middle Ages, with the road coming from Ifukugata no sho (伊福形荘) of Yose Gori, occupied by Shimazu going to Misu via Kono.
城は南の島津領寄郡伊福形荘から小野(この)を通って三須（みす）にいたる、中世までの幹線街道と大瀬川渡しを東から抑える交通の要衝に立地している。
