Takajomachi, on the Kagami River below Kochi Castle Ryokan with the only real hot spring in central Kochi ★★★★☆

Sansuien

高知城下の天然温泉 三翠園

Does Sansuien allow tattoos? Yes, covered

Cover seal required

Called directly in September 2026: allowed if covered. Bring your own seal; the property does not sell one. There is still no reservable private bath, and the room tubs are still not hot spring water, so the shared spring bath with a seal is the only way in.

Where it is
