The other day, I accompanied to the shooting of "Senkonoie".
It's the oldest thatched-roofed house in Fukui Prefecture built in the early Edo period.
There was "irori" in this house. Irori is a hearth made in the floor.
I saw it quite a long time. The fire was burned in irori.
It seems that because irori fire is also a role of the dehumidification and the preservation from decay. (Y.Y)
