Konoka Onsen
木の香温泉
An onsen ryokan at the foot of Mount Kanpu along Route 194 in Ino, Kochi. Its waters, flowing since the Edo period, are a gentle alkaline simple spring kind to the skin. The open-air bath overlooks the clear Yoshino River and is beautiful in every season - in spring you bathe beneath the cherry blossoms. The free-flowing sulfate water is said to ease cold sensitivity and fatigue, with day bathing 11:00-21:00 (last entry 20:00) at 700 yen for adults and 500 yen for children. A Michi-no-Eki Konoka is attached, and the lounge holds manga and children's toys, making it a family favourite. A year-round fishing pond lets you pair the onsen with stream fishing. Closed Wednesdays.

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.
