Built in 1894 and the first public bathhouse designated an Important Cultural Property, the Honkan is Dogo's symbol. Full operation resumed in 2024 after a five-and-a-half-year restoration. The ground-floor 'Kami no Yu' is ¥700 for bathing only; upper floors add a rest room with tea. Soft alkaline water. Quietest right after the 6 am opening or after 9 pm.
The locals' bath for anyone who wants to skip the Honkan queue. Same source water for ¥500 with almost no wait. Bring or buy soap.
An annex opened in 2017 in Asuka-period style with Ehime craftwork throughout, plus an open-air bath the Honkan lacks. Upstairs rest rooms and a private special bath limited to five groups a day.
A 390-year-old inn where Sōseki and Shiki once stayed. Two large baths (cypress and granite) with open-air tubs and saunas, all pure Dōgo water. Day use is ¥1,800 with towels and amenities included — a calm alternative to the crowded Honkan.
A large hot-spring hotel in the Ishite River gorge about 8 km inland from Dōgo Onsen. Its great open-air bath 'Suimei-no-yu', billed as one of the largest in western Japan, terraces some 26 tubs down the slope, where you soak in free-flowing alkaline simple sulphur water to the sound of the river — a 'beauty bath' with a clearer sulphur scent than Dōgo. Day use 15:00–20:00 (last entry 19:00), ¥1,100 for adults, irregular closures. The no-reservation private open-air baths 'Yunose' (¥4,400 for 45 min, 2–4 people, towels included) run until 23:00 and suit families or tattooed guests. A cold-spring pool operates in summer. About 50 minutes by bus from Matsuyama Station to 'Okudōgo', or 15 minutes by car from Dōgo Onsen Station.
A stay-all-day natural hot spring complex in Minami-Kume, Matsuyama, about 15 minutes by car from Dōgo Onsen, 15 minutes from Matsuyama IC and 5 minutes on foot from Iyotetsu Kume Station. It opens at 5 in the morning and runs until 1 am (last entry midnight) every day of the year. Alkaline 'beautiful-skin' water from deep underground fills the indoor, open-air and lie-down baths; a Finnish sauna offers löyly sessions, with a cold plunge and outdoor cooling deck. Admission is ¥1,750 plus ¥150 bathing tax for adults (members ¥1,350 + ¥150), including face and bath towels and loungewear, so come empty-handed; the rock-bed spa is ¥300 extra and children pay ¥1,000 with a locker. Reservable family baths, a recliner lounge, restaurant, body care and scrub salon and even lodging make it a full-day base for Matsuyama sightseeing, and on dates containing a 1 the 'morning bath day' rate drops to ¥1,000. Free parking for 250 cars. Ideal after Dōgo Onsen Honkan for a long, relaxed sauna and rock-bath finish.
