A number of coal mines existed in the Northern Kyushu, for example, in Chikuho, Takashima, Karatsu and Matsuura. We reserched the buildings attached to the coal mine ; such as coal-mine owner's houses, company houses, guest-houses and offices, in Fukuoka, Saga and Nagasaki Prefectures.
The former Takatori Koreyoshi's house was the oldest house among existing coal-mine owner's houses. All of the those houses are in Japanese-style and their receiving space is most important. But we find some diferrences in the entrance room, central corridor and Western-style room among them.
Company houses for the staff had some differece in quality accroding to their position. A house of the Mitsui Miike Mining Company in which Mr.S lives corresponds to Ko (first class) type and was built on the base of their standardized company houses.
It is important that Kurabu guest-houses such as the Hyakuenzaka Kurabu of the Mitsui Tagawa Mining Company and the Yamanoue Kurabu of the Mitsui Miike had Western-style rooms. The Hyakuenzaka Kurabu was originally consisted both of the guest-house named 'Settaisho' and the company house for the head official. They stood separately but were joined unplannedly by stairs after World War II.
Office buildings are classified into 5 types according to the function and business ; the head office, office standing in coal-mine, office standing in coal-pit, office standing in the port of shipment and office for persons in the same line of business. The former office of Matsuura Coal-Mine with stone wall and steel-truss structure was both the head office and the office standing in the coal-mine. It has characteristics both of locality and advancement.
