Lake Tateshina, Artificial lake in Chino, Japan

Lake Tateshina is an artificial reservoir in Chino, Japan, created by damming a stream. The lake has a shoreline of about 1.2 miles (2 km) and is surrounded by forest and hills, with a small island near its center.

The lake was created in the early 20th century as part of a hydroelectric project. Later, it became a popular spot for recreation and was developed with walking trails and picnic areas.

Local residents often visit the lake for picnics and fishing, especially on weekends. The small island, reachable by a footbridge, has a tiny shrine where people leave small offerings.

The lake is easily reached by car or bus from Chino Station, with parking available near the main access points. Walking paths circle the lake, but some sections are steep and may be slippery after rain, so wear sturdy shoes.

The lake's water level is managed for power generation, so the shoreline can change noticeably from one visit to the next. On clear days, the reflection of the surrounding hills on the water creates a mirror-like effect that photographers enjoy.
