Hokkawa’s Kuroneiwa Bath: What to Know Before You Go

Kuroneiwa is right at the water’s edge in Hokkawa, on the east coast of the Izu Peninsula. There is no hotel window between you and the Pacific: the public bath sits at sea level, with the sea and horizon in front of it. That is the draw. The trade-off is that this is a small, exposed outdoor facility, not a spa with a lounge and a long list of extras.

One important update comes first: as of September 27, 2026, the Hokkawa Onsen association’s official page is displaying a notice that Kuroneiwa has stopped operating because of an approaching typhoon. It says service will resume once high-wave danger has passed, but the notice does not give a reopening date. Check the official page or call before making the trip. The regular hours and prices below are the published schedule for when it is open.

Published hours and admission

The two rock baths at the front are for men; the round bath farther back is for women. Older travel posts may call Kuroneiwa mixed bathing, but the baths are now fully separate. Couples can visit together and bathe in their respective areas.

Kuroneiwa is a simple outdoor bath. Bring a small towel, as the facility does not offer the sort of amenities found at a hotel spa.

The sea is close; the weather matters

The pools are built beside the shoreline, so the ocean is more than a distant view. On a clear day you can look out across Sagami Bay; wind, cloud and rough water change the feel of the place quickly. Since the bath is outdoors, the same open setting that makes it memorable can also make a cold or stormy day less comfortable.

The official closure notice gives no date or reopening estimate. Since the bath is exposed to the sea, check the association’s latest notice before travelling; the regular 10 am–6 pm schedule does not confirm that it has reopened.

Reaching the bath

Izukyu-Izu-Hokkawa Station serves the small hot-spring settlement. Kuroneiwa is down by the shore; leave time for the walk back and check the return train before bathing.

Hokkawa is a quieter stop than Atagawa, and the train timetable matters if you are not staying nearby. Check the return service before you start bathing. For a larger hotel bath with a defined day-use ticket, the Atagawa Prince Hotel guide covers an option elsewhere along the coast.

Tattoos and other unanswered details

Tattoo admission is not specified. Contact the Hokkawa Onsen Tourist Ryokan Association at 0557-23-3997 before travelling if you need to know whether you can bathe.
