Take no Yu Onsen (Yukemuri Chaya) is located in Oguni, Kumamoto Prefecture. The sulfurous thermal water reaches 46°C here, with a pH of 6.5. The venue offers an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — 'Yukemuri Chaya' (湯煙茶屋 — hot spring steam teahouse) at Take no Yu Onsen (竹の湯 — bamboo spring) in the Waita area of Oguni. The Waita geothermal zone uses volcanic steam for traditional steam cooking (jigoku mushi) — a unique Kyushu culinary practice where local produce is steam-cooked in natural geothermal vents. The 'steam teahouse' combines these traditions: drinking tea, eating steam-cooked food, and bathing in the powerful sulfurous springs that define this extraordinary volcanic landscape.
