Livemax Resort Sanuki Shionoe Onsen (former Sanuki Onsen)

A lone inn in the hills of Shionoe, Takamatsu's traditional retreat and one of only two nationally designated therapeutic hot-spring areas on Shikoku. Its own pH 8.4 bicarbonate spring feeds a rotenburo above the stream, an indoor bath and a sauna, with a large free rest room. Day use in two sessions — 6:00–11:00 and 15:00–22:00 — for ¥700. Just 20 minutes by car from Takamatsu Airport, so handy before a flight.

Kagawa · ShōdoshimaTattoos: Allowed

Shōdoshima Olive Park Sun Olive Onsen

A roadside-station onsen on the hill of Shōdoshima Olive Park, right beside the Greek windmill made famous by film shoots. Big windows frame olive groves and the Seto Inland Sea; there are a herb bath, waterfall shower and sauna. The water is a radioactive (radon) spring. Owing to staff shortages, hours are shortened to 15:00–20:00 (last entry 19:30) from 17 July 2026 until further notice; ¥1,000, towel set rental ¥200. Closed all day Wednesday, and the onsen only on Thursday (holidays vary). Five minutes by car from Kusakabe port, ten from Ikeda port. Pair with a stroll around the park and the adjacent Olive Beach at island dusk.

Kagawa · Kan'onji & Kotohiki ParkTattoos: Ask ahead

Kotohiki Kairō open-air bathhouse, Kan'onji

A Japanese-style spa right by Kotohiki Park in Kan'onji, western Kagawa — famous for the giant coin drawn in sand, the Zenigata Sunae — and directly in front of Ariake beach. Its baths are inventive: a 'seawater onsen' bath, an ancient-cypress bath and a kama-buro steam bath recreating a 1,200-year-old design (alternating men/women daily), and the open-air bath looks over the Seto Inland Sea toward the sunset. Adults ¥950 on weekdays, ¥1,100 on weekends and holidays; open 11:00–23:00 (last entry 22:00), every day of the year. A sea-view restaurant, indoor and outdoor rest areas and lodging are attached. About 5 minutes by car from JR Kan'onji Station or 15 from Sanuki-Toyonaka IC; 500 parking spaces. Combine with the Chichibugahama sunset and the sand coin.

Kagawa · Shirotori Onsen, HigashikagawaTattoos: Ask ahead

Shirotori Onsen, Higashikagawa

A municipal cure-bath in a valley at Irinoyama, in the fold of the Asan mountains at the eastern tip of Kagawa. Quiet, wrapped in cherry blossom in spring and maples in autumn, it is a daily bath for locals and a long-standing lodging for pilgrims walking the Shikoku 88 temples. The simple sulphur cold mineral water is praised for its 'slippery-silky' cling on the skin. The layout is simple — main tub, bubble bath, cold plunge and sauna — with a view of hushed green forest. Very cheap at ¥400 for adults and ¥200 for children (and for over-70s); open 10:00–21:00 every day (occasional maintenance closures). The restaurant serves wild-boar hotpot and live-fish dishes, and rooms with two meals start from about ¥6,500. About 20 minutes by car from Shirotori-Ōchi IC on the Takamatsu Expressway, or by Ōkawa bus to 'Fukushi Center (Shirotori Onsen)'. Combine with a Sanuki udon crawl or the old townscape of Hiketa.

Kagawa · Takamatsu CityTattoos: Ask ahead

Takamatsu Crater-no-Yu Kirara

A natural hot spring super-sentō on Prefectural Route 12 in Ichinomiya, southern Takamatsu. It takes its name from the 'Takamatsu Crater', a roughly 4 km-wide buried structure beneath the plain thought by some to be a meteorite impact site, and draws its spring from about 300 m underground. The clear, soft water fills rock baths, pot baths, lie-down tubs and jet baths, with an open-air bath, sauna and cold plunge as well. Hours run from 6:00 in the morning until midnight (last entry 23:00), suiting both early dips and late stops, open all year (opening at 17:00 only on the third Tuesday). Adults pay ¥750 and children from infants to elementary age ¥350; towels are rented for a fee. A restaurant, rest space, overnight rooms and banquet halls keep it popular with locals, and barrier-free facilities are a point of pride. About 10 minutes' walk north of Kūkō-dōri Station on the Kotoden Kotohira Line, 20 minutes by car from Takamatsu Airport, with free parking for 200 cars. Good after Ritsurin Garden or a Sanuki udon crawl.
