In the countryside of Japan, there are many old private houses that have become vacant due to the declining birthrate, aging population, and urbanization.
Many of these old houses are neglected, fall into disrepair, and eventually can no longer be restored.
Despite the high value of the thick beams and pillars in their natural form, and the elaborate furnishings, they are being abandoned.
However, the wonderful thing is that the pillars and beams of old houses can be reassembled once they are dismantled.
This is because they are assembled using only the combination of wood and wood without using bonds or nails.
