The folk house named Syuraku-an is one of few existing thatched houses in Nadasyo village. The NPO group restored this abandoned house in 2008 with financial support. They now use it for nature experience programs for urban children. The traditional thatched house in use at the present time is quite valuable, whereas the maintenance, in particular for a thatched roof, requires a significant cost to outsource professionals and purchased materials, or a significant labor force raised from the community. The heavy work of re-thatching a whole roof is necessary in the future; however, it is difficult to repeatedly expect sufficient funds or to ask for community cooperation in a depopulated and aging village. The NPO group has a plan for the next re-thatching to establish a new community network with the help of participating members in the younger generation. The sustainability of the thatched house is a long-term challenge.
