Insider tip — 'Hiryu no Yu' (飛龍の湯 — flying dragon spring) at Myohoji Onsen (妙法寺 — Wonderful Law Temple) in western Karatsu-Saga. The Myohoji Temple name recalls the Lotus Sutra's 'Myoho' (妙法 — wonderful dharma) — the central text of Tendai and Nichiren Buddhism. The flying dragon is a powerful Buddhist symbol of transformation and transcendence. A temple spring in the Kyushu hills where the dragon's fiery energy rises as geothermal water: a perfect synthesis of Buddhist imagery and volcanic geology.
