Koumi

Koumi is a small town in Nagano Prefecture, in the Minamisaku District of Japan's southern alpine region. It sits in a mountain valley surrounded by forested hills, with traditional wooden buildings and residential areas forming the main settlement pattern.

The town developed as an administrative unit in a mountainous area traditionally oriented toward forestry and small settlements. Over time, it has maintained its rural character as a sparsely developed community in the highlands.

Visitors should be prepared to move at the quiet, slower pace of a mountain town where most services remain concentrated in the center. The best way to explore is on foot along the calm streets, especially during clear weather, as the terrain includes steep sections.
