Structure of a KOMINKA
The skeletons that support old houses are often quarried from the mountains, never shaped, and utilized in their original form.
In Japan, where most of the land is surrounded by mountains, villages and mountains are close together, and people used to use trees cut from the mountains that were protected by their ancestors for their own houses.
More than a hundred years ago, transportation and processing technologies were not widely available, so it was necessary to use wood cut directly from the mountains right behind the house. Because of this, carpentry techniques were developed to put together pieces of wood that were not identical in shape.
