The municipal facility for Ibusuki's famous natural sand bath. Change into a rental yukata, walk down to the beach, and staff bury you in hot sand for about ten minutes; afterwards rinse off in the indoor onsen. At high tide the sand baths move under a roof. ¥1,500 includes the yukata; bring or buy a towel. 20 minutes on foot or 5 by bus from Ibusuki Station.
A vast garden bath hall fed by 14 sources at 1,400 litres a minute, with four water types — sulfur, alum, saline and iron — in one place. The central pool is mixed-gender (women-only hours; bathing garments allowed).
A public bath from the early Shōwa era beside the ruins of the Shimazu lords' private bathhouse. The Shimazu crest decorates the tub; the salty water runs hot and free-flowing. Free drinking spring too — a local follow-up to the sand bath.
About 5 minutes by car from Kirishima Shrine, a rare inn with a natural mud bath. Scoop the grey mineral mud from the milky sulfur pool and use it as a body mask in the open-air bath. Day use 11 am–8 pm, ¥900 — the classic stop after the shrine.
A day bath inside a public inn 15 minutes by ferry from Kagoshima port and 8 minutes' walk from Sakurajima port. Water rises at 51°C from a magma layer 1,000 m below, clouded rust-brown with iron, and flows freely through a bath hall looking across Kinkō Bay to the city. ¥460, 11:00–21:00 — a bargain after touring the volcano or the lava seaside trail. The free 100-metre Lava Nagisa Park footbath is within walking distance. Operations may be affected by volcanic alert levels.
In the town centre of Ibusuki, famous for its sand baths, this is one of the oldest communal baths, dating from 1882. Locals call it 'Muran-yu'. Its pride is the wooden bathhouse and the spring that wells up straight through the floor of the tub; there are no taps — you scoop the emerging water with a bucket to rinse, the old way — and there are two tubs, hot and lukewarm. The sodium-chloride water is strongly salty in true Ibusuki fashion and keeps you warm for ages. Adults drop ¥350 into the unattended fee box; open 08:00–22:00. No soap provided, so bring your own. About 13 minutes on foot from Ibusuki Station. For onsen fans who want a 'real locals' bath' after the Saraku sand-bath hall; entry may not be possible during cleaning or crowding, so check closure days in advance.
The oldest naturally rising spring of Hinatayama Onsen, the spa district along the Amori River in Hayato, Kirishima, about 15 minutes by car from Kagoshima Airport. Saigō Takamori is said to have favoured it between hunts, and locals call it 'Segodon's bath'. It is unstaffed — you drop your fee in the box at the entrance — and the price is frozen in the Shōwa era: ¥250 for adults, ¥100 for children. Inside is a simple indoor bathroom with two tubs, hot and moderate, filled free-flowing with clear, slippery bicarbonate water; there is a drinking fountain of the spring too. No open-air bath or restaurant, but it opens 06:00–21:00 (last entry 20:30) and a room-only lodge next door costs ¥1,800 including the bath — a boon for travellers. Closed the fourth Monday. About 5 minutes on foot from JR Hinatayama Station; 10 parking spaces. For anyone wanting an unadorned everyday Kagoshima bath before or after Kirishima Shrine or the airport.
The lookout open-air bath of a long-established hotel crowning Shiroyama hill above Kagoshima city. Facing Sakurajima across Kinkō Bay, the outdoor bath is celebrated as one of Kagoshima's finest views, and after dark the city lights and the smoking volcano's silhouette are magical. The bicarbonate spring from 1,000 m underground is a skin-smoothing 'beauty bath', offered in indoor and outdoor pools plus the 'Ion Spa' hot spring sauna. Day bathing runs 13:00–21:00 and costs ¥3,500 for adults (tax and bathing tax included), ¥3,350 for junior-high students, ¥1,750 for elementary pupils and ¥800 for infants. It is pricey, but face and bath towels are included and you can use the hotel lounge, the Ippinkan gift shop and restaurants, making it a popular splurge for the view alone; reservable private baths start at ¥4,950 on weekdays for day guests. A free shuttle bus takes about 15 minutes from Kagoshima-Chūō Station, or 10 minutes by car from Tenmonkan. Pair it with the Shiroyama observatory and Saigō Takamori's historic sites and make a soak facing Sakurajima the highlight of your trip.
A large resort hotel in Maruo, in the Kirishima spa group, taking day bathers from 11:00 to 15:00 with last entry at 14:00. The fee is 1,200 yen for adults, 600 yen for elementary pupils and 300 yen for children aged 3 and over (tax included). Milky, turbid water is its hallmark, and there are many tubs: the main hall Onami-no-yu, the open-air Kiri-no-yu, a hinoki steam bath, a natural onsen steam bath and a cold plunge. Each bath has a scheduled cleaning day set by weekday and by odd or even date, so some are unavailable. The hotel may close over New Year, Golden Week, Obon and public holidays, so calling ahead is advised. It stands just off the Maruo crossing on Route 223, with free parking.
The top-floor observation onsen of the Kagoshima Sun Royal Hotel in Yojiro, facing Kinko Bay. A natural chloride spring, heated and diluted, its top-floor bath looks out over the majestic Sakurajima; there is a far-infrared sauna for men and a steam sauna for women, and day visitors are welcome.
A large day-bathing facility at Hinatayama Onsen in Hayato, Kirishima City, also handy from Kagoshima Airport. The spring is a sodium-bicarbonate type (hypotonic, weakly alkaline, hot) at pH 7.8 and 56.4°C at the source, loved as 'beauty water for beautiful men and women' for its smooth feel. Cypress baths, a jacuzzi and a foot bath sit indoors, with an open-air bath and rock-plate bath alongside, and the spacious cold plunge after the sauna is a favorite.
A retro hotel on the shore of the Furusato Onsen area on Sakurajima's southeastern coast in Kagoshima City. Its murky sodium-chloride spring (Furusato No. 15 and No. 16 sources, about 46-48°C) runs kake-nagashi and is prized for warming and moisturizing the skin. The mixed-gender open-air bath sits right at the water's edge with wide-open Kinko Bay below - dolphins are sometimes spotted offshore. Separate indoor and outdoor baths for men and women and a family bath are also available.
