5 Facilities
An open-air-only bath at the edge of the Pacific. One of Japan's oldest springs, mentioned in the 8th-century Nihon Shoki; on rough days sea spray reaches the tubs. No roof, no wash stations.
Shirahama's other classic public bath, on the Yuzaki seafront near Saki-no-yu. Its draw: two distinct springs — Mabuyu and Miyukiyu — under one roof. 7 am to 10 pm, ¥420.
A town-run bathhouse right in front of Shirara-hama, the famous white-sand beach. Built like an old-fashioned sentō with an attendant's counter, its second-floor bathroom opens through big windows onto the beach, blue sea and sky — a ¥420 view bath you would never expect in a resort. The 66.8°C sodium-chloride 'Suzushi-yu' source flows freely, and the strongly salty water keeps you warm long after. Open 09:00–11:00 and 14:00–21:30 (last entry 21:00; 07:00–09:00 is residents only), closed Thursdays. Soap and shampoo sold for ¥40; no hair dryers. One of Shirahama's 'sotoyu' circuit with Saki-no-yu and Muro-no-yu — locals rinse off the sand after a swim and come straight in. About 15 minutes by bus from Shirahama Station to 'Shirarahama'.
A day-bath house standing in a grove a little way from the Shirahama spa street. It was built around the frame of a wooden storehouse from the early Showa period, on the ground of the old Koga bath that dried up and closed, reopening the spring as Chosei-no-yu. There are three tubs: an indoor bath recalling a Showa-era healing resort, a bath lined with Kishu bincho-tan charcoal, and an open-air bath ringed by cherry and maple. Shirahama's spring runs through it unrecycled, and the mildly alkaline sodium bicarbonate chloride water is known for leaving skin smooth. 900 yen for adults and 500 yen for children, 10:00 to 22:00, closed Wednesdays (or the next day if Wednesday is a holiday), parking for 22. A ramen shop sits on the same grounds.
A large day-bathing complex on the grounds of the popular Toretore Market, packed with fresh seafood, in Shirahama, Wakayama. Alongside a main bath fed by Shirahama Onsen water, it offers six characterful open-air baths and a rock-bath (ganban-yoku) room open to men and women together - a full day's fun for families and couples alike. Long hours from 9:00 to 23:00 (last entry 22:30) make it an easy final stop after touring Nanki. Admission is 850 yen for junior high and up and 420 yen for ages 3 to elementary (some sources list 980 yen - confirm locally). Free parking for 100 cars; about 5 minutes by taxi from JR Shirahama Station, with easy access from Nanki-Tanabe IC too. Soak, then enjoy seafood bowls and local fish shopping at the market - a distinctly Shirahama experience. Closed a few days a year for equipment checks.
