A place where the floor is hollowed out and ash and charcoal are put in to make a fire. Used for fireplaces and cooking. In the same role as the dining room, it seems that he enjoyed eating and tea while surrounding the 囲炉裏-Irori.
The smoke generated in this 囲炉裏-Irori smoked the entire house, making it less susceptible to insect erosion and also helping the house last longer.
I hope you enjoy woodworking with Suikoushya!
