At an altitude of 650m to 1500m, the sunny weather and cool climate nurture high-quality agricultural products such as highland vegetables and fruits. It has prospered as a post town on Nakasendo since ancient times, and the fermented food culture such as miso-based dishes and pickles is still rooted in the people’s lives. The nutritious carp dish is a local soul food. No wonder it’s a prefecture known for health and longevity.
