Lake Sayama (Yamaguchi Reservoir)

Completed in 1934 to supply Tokyo with water, this reservoir lies among the wooded hills associated with the landscapes of My Neighbor Totoro. The embankment overlooks Mount Fuji and the Chichibu mountains on clear days. Spring blossoms, cycling and gentle walks make it a peaceful escape.
