My younger sister lives in Shizuoka and she and her husband built their house about 13 years ago.
I went their house the end of last week and I was impressed by their house because the house had no air conditioner.
Her mother-in-law said that it's warm in winter and not so hot in summer because of the climate there.
I thought that it was an ecological house.
However, there is one problem.
It is said that a huge earthquake will occur near future in the place.
