comment：Carbonized wood found in the western area of the wall of the opening side wall of Pit House 8. It can be seen that the wall was covered with pieces of bark, and inside them wooden boards—made by splitting logs—were arranged with the outer surface facing inward. The material is 15 to 20 cm wide boards of Abies sachalinensis.
