A Japanese style mansion created within a period of one and a half years as the cottage of a businessman. This is a two-storied Irimoya-zukuri (a hip-and-gable roof structure) facing south with an L-shaped single-storied building attached to the west and another single-storied building attached to the south-east. This was designed based on Kyouma in Sukiya-style using excellent lumbers such as hinoki (Japanese cypress). It shows various examples of delicate shaping at numerous places. This was used as the Swiss embassy before moved to the current location.
