Insider tip — Yakuoji Onsen Kairakuso, the mutual enjoyment lodge of the Medicine King Temple spring, serves Koga City on the northern Fukuoka coast where the ancient Ito Kingdom once welcomed Chinese diplomatic missions whose records in the Wei Zhi chronicle provide some of the earliest written descriptions of life in the Japanese islands. The kairakuso (shared pleasure) philosophy of communal thermal bathing is at the very heart of Japanese onsen culture.
