The Gifts of Mt.Fuji and Coexistence with a Volcano
What would our lives be like without
Mt. Fuji? Without Mt. Fuji, this area would certainly have
been full of steep mountains and valleys. As Mt. Fuji formed
and continued to erupt, valleys were slowly filled in by mud
and lava, and the surrounding terrain was leveled. Mt. Fuji
also gives us gifts of clear, clean water and mineral rich
soil thanks to volcanic ash deposits.

area developed when a large lake resulting from lava and
mudflows dried and left only fields. Ground water beneath
this area gushes to the surface and forms the Oshino Hakkai

and divided it into the current Lake Shojiko and Lake
Saiko. The same lava flow currently provides a fertile
bed for the Aokigahara Forest.
