The former Sorachi Coal Mine Club was built in 1897 by Hokkaido Coal Mine Railway Co. It was extended and remodeled many times, and became a club exclusively for entertainment in 1954, and even after it was taken over by Sorachi Coal Mine Co. Although some of the buildings were demolished, the Western-style main building and the Sukiya-style annex were restored and nicknamed "Komorebi-no-Mori Memorial Hall" to preserve them for many years to come, as they remind us of the heyday of the coal mine.
