Welcome to Lake Tama !

Lake Tama is the symbol of Higashiyamato City.  It was formed by damming up a river running through a Sayama hills valley.  The Lake now serves as reservoirs (Kami Chosuichi and Shimo Chosuichi), and each of them is provided with a dam.  This man-made lake and a nearby source forest occupy about a quarter of the whole area of Higashiyamato City.

The waters of the Tama River are preserved in Lake Tama for Tokyo, and are sent to remote water purification plants through the Lake’s water towers.

The construction of the lake dam began in 1916, and it was actually almost handwork.  It took more than 10 years to finish this task.  The Lake finally saw the completion of the dam creation in 1927.

At the time of the start of the dam project, there were seven villages at the foot of the river valley mentioned above.  The people there had led pleasant, comfortable lives on agriculture.  However, they had to leave their habitats due to the “lake development”.  There is the Keisho-mon Gate situated to the north of the Kami Entei upper section of the dam.  It is the gate to the Keisyo-in Temple now located at 6-chome, Imokubo.  This temple gate has remained intact as a “conveyer” of those old days of the villagers’ easy living.

Lake Tama can also be found in the “Shin Tokyo Hyakkei” (100 new scenic spots of Tokyo) designated in 1982, and in the “Higashiyamato Nijukkei” (20 scenic spots of Higashiyamato) designated in 1990.  The Lake is quite popular throughout the year.  It presents fantastic views to visitors in the seasons of cherry blossom viewing, spring leaf sprouting, autumn leaf reddening, and winter snow falling.

There is the Lake Tama cycling course extending from Nishi Tokyo City to Lake Tama.  The road around the Lake promises a wonderful time to every cyclist.
