Mechanism

The winter monsoon that blows from the Eurasian continent toward Japan contains water as it crosses the Sea of ​​Japan. In general, there are mountain ranges in the central part of the Japanese archipelago, so on the Sea of ​​Japan side, this wind becomes a rainy season and causes rain and snow to lose water. As a result, the Pacific side beyond the mountains becomes dry air, which blows through and causes tree withering.
