The Hondo main hall has the Yosemune-yane (roof that descends from the ridge on four sides of a rectangular building) thatched with cypress bark, also having transepts of Irimoya-zukuri style (building with a half-hipped roof) on both sides of its south-facing facade, all of which provide its external appearance with unique features.
屋根は寄棟造、檜皮葺きで、正面（南面）左右に入母屋造の翼廊が突き出し、外観に変化を与えている。
