Insider tip — 'Onka no Haru' (恩花の春 — grace-flower spring) at Asagiri-cho Fureai Onsen. Asagiri-cho was formed from merging four communities in the Kuma basin — Hitoyoshi, Mitsue, Fukuro, and Sagara — creating a town that spans both sides of the Kuma River. 'Onka no haru' combines gratitude, flowers, and spring season into a single name for the community's shared thermal water. The fureai (community exchange) format is the social institution that holds these merged communities together.
