Obama Onsen Hama-no-Yu Municipal Bath
Obama Onsen in Unzen, Nagasaki, is famed for sunsets over Tachibana Bay and for spring water near 100°C – the highest heat output of any onsen town in Japan. Hama-no-Yu is the city-run, old-fashioned public bath of this seaside spa: a classic sentō layout with an attendant's booth and two deep tubs, hot and tepid, brimming with alkaline simple spring water. No soap or shampoo is provided (sachets are sold) – there is nothing here but the water, and bath lovers cherish that purity. Admission is an astonishing ¥300 for ages 12 and up from outside the city (Unzen residents ¥150), and ¥100 for ages 6 to under 12; open 6:00–22:00 (last entry 21:30), irregular closures. There is room for some five cars, and the nearby Yūhi-no-Hiroba lot is free. Along the shore are Japan's longest footbath, the 105 m 'Hot Foot 105', and steam cookers, and it is fun to bath-hop to the Wakihama public bath (¥200). About an hour from Isahaya Station by Shimabara Railway and Shimatetsu bus, or an hour by car from Nagasaki city. Taste Unzen's mountain baths and Obama's sea baths in a single day.
