Okayama · Tamano & Uno Port
Setouchi Onsen Tamano-yu
瀬戸内温泉 たまの湯
A stay-awhile day spa about 7 minutes on foot from JR Uno Station, right beside Uno Port where the ferries to Naoshima and Teshima depart. Jazz plays through the calm, old-farmhouse-style interior, and the great draw is the open-air bathing area gazing over the islands of the Seto Inland Sea and the boats passing between them. Outside are four baths around a large rock pool plus pot tubs; inside two pools, a sauna and cold plunge, with a rock-bed spa for an extra fee. The soft sodium-chloride spring rises from underground, and a soak in the sea breeze is the perfect cure for a day of art-island walking. Admission is on the high side – ¥1,700 for adults on weekdays and ¥2,000 on weekends and holidays (children ¥700/¥800) – but towels and loungewear are included, and a recliner lounge and restaurant serving Setouchi fish let you settle in for the day. Open 10:00–22:00 (last entry 21:00), closed the third Tuesday (the following Wednesday if a holiday), parking for 200 cars. A rare chance to bathe while waiting for the ferry back from Naoshima; about 40 minutes by car from central Okayama.

- Baths
- A stay-over day-use onsen a few minutes on foot from JR Uno Station, right beside Uno Port, from which the ferries for Naoshima and Teshima sail. Jazz plays through a calm interior in old-farmhouse style, and the greatest charm is the rotenburo looking out over the islands of the Seto Inland Sea and the boats passing between them. There are four outdoor baths centred on a broad rock bath, plus pot baths and two indoor tubs, with a sauna, a plunge and a heated-stone bath charged separately. Towels, bath towels and lounge wear are included in the fee, so you can come with nothing, and with a rest room of reclining chairs and a restaurant using Seto fish, a whole day can be spent here
- Spring water
- A calcium and sodium chloride spring welling from underground. Soft water with good heat retention that warms the body well, and soaking in the rotenburo in the sea breeze loosens the tiredness accumulated touring the islands of the Seto Inland Sea. From the rock bath outdoors you see the ferries crossing Uno Port and the islands of the Inland Sea, and at night the harbour lights are reflected on the water. Indicated for joint pain, poor circulation, cuts and women's complaints
- Access & parking
- 3–5 minutes on foot from Uno Station on the JR Uno-Minato Line, and right beside Uno Port (the ferry terminal for Naoshima and Teshima). By car about 60 minutes from Okayama IC on the San'yō Expressway, about 40 from Okayama city, and reachable from Kojima and Shikoku too. Free parking for 200. Its position makes it easy to place at the start and the end of an art-island trip around Naoshima, Teshima and Inujima

An onsen met in front of the boats for the art islands
Setouchi Onsen Tamano-yu is a stay-over day-use onsen in Tamano, Okayama, standing right beside Uno Port, from which the ferries for Naoshima and Teshima sail. It is a few minutes on foot from JR Uno Station and visible from the port, so there is no better place to loosen up on the way back from touring the art islands. The interior is a calm wood tone recalling an old farmhouse, with jazz playing, giving it an atmosphere closer to the rest room of a ryokan than to a super-sento. The centre of the facility is its rotenburo. There are four outdoor baths around a broad rock bath, plus pot baths, and from anywhere you sit the islands of the Inland Sea and the boats crossing Uno Port come into view. The water is a calcium and sodium chloride spring, soft with good heat retention, loosening the tiredness of walking the islands and leaving the body warm afterwards. Inside there are two indoor tubs and a sauna and plunge, and a heated-stone bath (¥1,000 for the day) charged separately, so half a day can be spent moving between onsen and stone bath. Admission is ¥1,700 for adults (junior high and up) on weekdays and ¥2,000 at weekends, which feels somewhat high, but towels, bath towels and lounge wear are all included (lounge wear for adults only), and with a rest room of reclining chairs and the restaurant Kairō using Seto fish (11:00–14:30 and 17:00–21:30) it is easier to accept as the price of a day rather than of a bath alone. Hours are 10 a.m. to 10 p.m. (last entry 9 p.m.), closed the third Tuesday (the following Wednesday if a holiday), with parking for 200. It is 40 minutes by car from Okayama city and a few minutes on foot from Uno Station, so it fits at either end of a trip around Naoshima, Teshima and Inujima, and warming up while waiting for a ferry is a common way to use it here. Special rates apply over Golden Week, Obon and the New Year, so it is worth checking before you go.
The rotenburo, the stone bath, and staying a whole day
Walk over from the free car park (200 spaces) or from Uno Station and pay at the entrance (¥1,700 on a weekday). Towels, a bath towel and lounge wear are included, so you need bring nothing; take a locker key along with your shoe-locker key and go up to the baths on the second floor. A recommended circuit: wash and soak 10 minutes indoors; go out to the broad rock bath of the rotenburo and spend 20 minutes looking at the islands; 15 minutes moving between the pot bath and the other outdoor baths; 8–10 minutes in the sauna, a minute in the plunge and 5 minutes on the open-air chairs, three sets; with time, 30–40 minutes in the heated-stone bath (¥1,000 for the day, robe and large towel included); and finish outdoors. The calcium and sodium chloride water is soft with good heat retention, so alternating it with the stone bath warms the body deeply. Afterwards rest in the rest room of reclining chairs and eat lunch or dinner of Seto fish in the restaurant Kairō to fill the day — there are also relaxation and body-scrub services (11:00–21:00, last entry 20:30), good for loosening up while waiting for a boat. Dropping in before the ferry to Naoshima or Teshima, or after coming back from the islands, is the most ordinary way to use this onsen, and being minutes from Uno Port it combines freely with ferry times. Notes: closed the third Tuesday (the following Wednesday if a holiday); last entry 21:00; the stone bath is for junior high and up and costs extra; lounge wear is for adults only (children rent for a charge); special rates over Golden Week, Obon and the New Year; cash and cards accepted. Tamano-yu is an onsen for warming the body while looking at the Seto Inland Sea, and scores highly at either end of an art-island trip.
