The former Isobe manor, located in Nakahommachi, is a wooden house that preserves the architectural style of the Edo period. In former times since the Edo period, a drapery business was operated here under the name Kashiwaya Magobei. The property is 6.8 meters wide at the front and 53 meters deep. It consists of a main house, storehouse, rear storehouse, and shed.
The main house is built in the banko style, with a low-ceiling second floor at the front but none at the back. The roof of the main house is a mukuri-yane roof that is cambered (slightly convex in shape) — the only merchant’s house its kind in Inuyama.
