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.

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.
