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.
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.

There are several iconic spots to explore within Takase Valley:
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. Since the river flow and scenery change with the seasons, we recommend planning your visit based on the time of year. Summer offers a refreshing, cool environment, while autumn provides a spectacular display of color.

Visitors can enjoy walking and light trekking through the natural landscape. There are routes that allow you to feel the energy of nature while viewing the massive dams. Additionally, the nearby hot spring areas offer the chance to soak in warm waters while surrounded by the changing seasons, providing a multi-sensory experience of the natural world.
