Mountains
Japanese people lived on coastal plains because most of Japan has mountainous slopes that are difficult to live on and farm.
Generally along the coast, but some people still farm up in the mountains.
The availability of fertile soil, access to water sources for irrigation, and the presence of a variety of wild plants and animals for domestication were key factors that allowed Neolithic people to farm in the foothills of the Zagros mountains.
