Chikusei, in the western Ibaraki Prefecture along the Kinu River, was formed from the merger of Mitsukaido and Sashima to create a large municipal area in the flat Kanto plain rice farming landscape, known for the traditional Sashima tea cultivation that has produced green tea in the Sashima hills for centuries using terraced garden techniques characteristic of the Kanto mountain foothills. Chikusei Onsen Ibaraki draws on sodium and bicarbonate thermal waters from the geological resources of the western Ibaraki lowlands, offering restorative baths in a merged agricultural community whose Sashima tea heritage, flat Kanto plain scenery, and Kinu River waterway culture create a gently traditional and unhurried spa setting in western Ibaraki Prefecture. The Sashima tea gardens on the low hills above the Kanto plain, the traditional Kinu River fishing and ferry heritage, and the flat agricultural cycling routes through the western Ibaraki rice paddies create a pleasantly traditional rural backdrop for thermal spa relaxation in this western Ibaraki community.

Insider tip — Chikusei, formed by the merger of several agricultural communities in central Ibaraki, taps a bicarbonate spring from the vast sedimentary layers of the Kanto interior. The water is clear, mildly mineralized, and comfortable for extended soaking. Surrounded by vast vegetable fields and nurseries supplying metropolitan Tokyo, this rural bath offers an authentic slice of farm-country Japan rarely seen by visitors.
