OSHINO HAKKAI literally means "Eight seas at OSHINO" which are
between NAKAYAMA 
and KAWAGUCHI lakes. This area were a big lake called lake Utsu, but Enryaku
eruptions
in 1707 and 1708 divided it into two, Oshino and Yamanaka lakes. Afterwards, Oshino lake 
dried up into many fountains where ground waters from Mt. Fuji sprung up.
We have eight fountains now at Oshino where crystal ground waters at 12
degrees gush out
all the year around. It comes from snow fallen on the slope of Mt. Fuji and is thought 
to take 20 years to spring out there.
Accordingly the ground water is very transparent and fresh, and the eight
fountains are 
designated as national treasure.
