Insider tip — 'Rinsen no Yu' (隣泉の湯 — neighbouring spring waters) at Reihoku-cho Onsen Center on the western tip of Amakusa's lower island, facing the open East China Sea. Reihoku (苓北) is one of the most remote municipalities in Kumamoto — isolated by sea on nearly all sides, accessible only by ferry or the long coastal roads of Amakusa. The community onsen here is genuinely the social centre of this island tip, where fishing families gather after the Amakusa sea.
