The nagayamon gate (row house gate) of the Takadas, a middle-class samurai family, has been open to public since it was restored. The nagayamon gate incorporates a servant room and stable. Visitors will know the roles of middle-class samurais and their servants and lives in those days. The garden having the pond in round-the-pond style with water taken from the Onosho canal is one of the highlights of the remains.
