Inashiki, in the southern Ibaraki Prefecture along the Kasumigaura lake shore, is an agricultural community on the broad flat lowlands between Lake Kasumigaura — Japan's second-largest lake — and the Tone River border with Chiba, where traditional freshwater fishing, eel farming, and lotus root cultivation have sustained the lakeside communities for generations. Inashiki Onsen Ibaraki draws on sodium and bicarbonate thermal waters from the geological resources of the southern Ibaraki lacustrine plain, providing warm restorative baths in a lakeside agricultural community where the vast Kasumigaura shoreline, traditional eel cuisine, and flat cycling routes create an appealingly tranquil and watery spa setting. The Kasumigaura Lake cycling circuit — at 180 kilometres one of Japan's most celebrated lakeside cycling routes passing through traditional fishing villages and reed marshes — the fresh freshwater eel (unagi) cuisine of the lakeside restaurants, and the open water sailing and windsurfing culture of Japan's second-largest lake make Inashiki a pleasantly watery and active spa destination on the Kasumigaura shore.
