Haruno-no-Yu Natural Onsen, Kōchi
天然温泉 はるのの湯（高知・春野）
A hot-spring complex on a rise in Haruno, Kōchi city, about 30 minutes by car from Kōchi Station, looking out over rice fields. Its big open-air bath fed by an abundant natural spring is the draw, with an indoor bath, a sand bath that warms you to the core, and in July–August a swimwear spa zone (pair baths, a children's spa and so on — ten in all), so families are many. Day bathing: adults ¥700, children ¥300, over-65s ¥500; open 10:00–21:00 (last entry 20:15), every day apart from occasional maintenance. The Haru Noie restaurant serves a weekly lunch, and a lodging wing with open-air-bath rooms starts at ¥8,650 with breakfast; being near the Haruno sports park it also hosts training camps. About 40 minutes by car from Kōchi Ryōma Airport, or 15 minutes on foot from the terminus of the Tosaden bus for JA Haruno; 60 parking spaces. A rare large open-air bath within Kōchi city, easy to fit between Katsurahama and the Niyodo Blue river.

Sansuien Suisaikaku Onsen
The bath wing of a historic hotel built on the site of the Yamauchi lords' residence below Kochi Castle. A rare natural hot spring in central Kochi, with a rotenburo facing the Kagami River and Mt. Hitsuzan, a large indoor bath and sauna. Day use is daytime only, 10:00–16:00. Fifteen minutes on foot from Harimaya Bridge — easy between sightseeing and the Sunday market. ¥1,200; bring or rent a towel.
Tosaryu Onsen Sanyoso
Forty minutes by car from Kochi city, a hot-spring inn beside Shoryuji, temple 36 of the Shikoku pilgrimage. It claims Kochi's only high-concentration, high-temperature spring; the golden chloride water is nicknamed 'the heat bath' for how long it keeps you warm. The rotenburo looks over Usa Bay and the Pacific, and there's a free seaside footbath. Day use in two sessions — 5:30–9:00 and 14:00–21:00 — ¥750 on weekdays.
Hotel Matsubakawa Onsen (Shimanto)
A solitary inn on the Hinoji River in the Shimanto headwaters. Its viscous, highly alkaline water has been revered as a healing spring since the Edo period, and a day soak is a modest ¥700. Enjoy the open-air bath above the stream or book a private bath. Open late, 10:30–21:00, and 30 minutes by car from Kubokawa Station—ideal after canoeing or cycling the Shimanto.
