Lake Okutama is an artificial lake formed by Ogouchi Dam located upstream of Tama River.

It is located about 60 km west of central Tokyo, and the west part of the lake extends into Yamanashi Prefecture.

This lake is very important as one of the water sources of Tokyo area.

Ogouchi Dam (小河内ダム) took 19 years to build because of interruption of construction by World War II.
It was completed in 1957.
During the construction, 87 workers died in some accidents, so the memorial has been built in 1958.
