Insider tip — 'Parea' (from Greek: friend group) at Genkai Kaijo Onsen — a marine-view hot spring in Genkai-cho, on the Genkai Sea coast of Saga. The Genkai Sea (玄界灘) is the body of water between Japan and Korea, historically the crossing point for cultural exchange over millennia. Genkai-cho is also home to the Genkai Nuclear Power Plant. The Greek-named spa, on a coast that faces Korea, captures Genkai's position at the crossroads of ancient and modern Japan.
