During Edo-Era inspectors were sent throughout Japan several times. In 1838 inspectors were sent to Kumamoto-Han and used private houses for stay and rest.
Through the examination of historical materials such as plans, following results were ascertained;
1)Inspector's room, followers' rooms and storeroom were required for stay and rest in private house.
2)Most of the private houses were composed of 3 or 4 rooms. So room was divided into different spaces to meet the requirement.
