The main building, the former Asada Residence, was built in 1932 and was the former residence of Teijiro Asada's third son, Yozo. The annex was constructed in the mid-Meiji period as a retirement room for Masutaro Kikkawa, the sixth generation head of Izutsuya.
Teijiro Asada (1871-1942) was the head of 11 towns and villages around the Silver Mine, and later served as a member of the Hyogo Prefectural Assembly and House of Representatives. He also contributed to the development of Ikuno Town by establishing Ikuno Bank in the same year and becoming its first president.
The main building, the Asada Residence, is a stately two-story wooden design with a gently arched hip-and-gable roof. There is a hanging fish attached to the entrance roof, a ceremonial platform at the entrance, and a Western-style building with a triangular roof and scratch-tile exterior walls, all of which are unusual for a private house remaining in Ikuno.
The annex, the former Kikkawa Residence, was built in the mid-Meiji period as a retirement room for Masutaro Kikkawa, the sixth head of the Izutsuya family of the Country Inn. It has distinctive features such as the sleeve walls, the Mezzanine building, and the box staircase.
