Takase Valley

Overview & Charm

Takase Valley is a vast natural area featuring three major dams (Omachi, Nanakura, and Takase) along the Takase River, seamlessly integrated with nearby hot spring areas. The landscape is defined by the striking contrast between massive dam structures and the raw beauty of nature. The scenery changes beautifully with the seasons, reaching its peak during autumn when the emerald green river is framed by brilliant, colorful foliage.

History & Cultural Background

The Takase River flows through Omachi and Azumino in Nagano Prefecture. The name "Takase" is said to have originated during the mid-Heian period, when the river's name was chosen to mirror the Takase River in Kyoto to reflect the way the area was developed. Today, the region is a unique blend of water resource management through its dams and a thriving tourism culture centered on natural scenery and hot spring traditions.

Best Seasons & Timing

The highlight of Takase Valley is undoubtedly the autumn foliage season, particularly from mid-October to early November. During this time, the contrast between the emerald water and the colorful trees is at its most vivid.

Summer offers a refreshing, cool environment, while autumn provides a spectacular display of color.
