The work was carried out on the gassho-style house "Myozenji Koura" built about 200 years ago. More than 5 people, including local elementary and junior high school students, participated in the work.

In Shirakawa Village, due to the declining birthrate and aging population, the number of people who ask specialized contractors is increasing.
