Insider tip — Nukumori no Yu, the warmth spring of the Satomi Hoyo Centre, serves the upland Satomi district of Hitachiōta City where the medieval Satomi clan ruled the Hitachi Province highlands before the Tokugawa unification. The Nansen-ji temple and scattered clan-era fortification ruins survive in the forested ridges above the Satomi valleys, and autumn foliage along the upper Naka River rivals any in the Kanto region.
