Miyahama Onsen Day Baths: Which of the Three Fits Your Visit?

Compare Benimansaku no Yu’s sauna and restaurant with Kanzaki’s lower-priced bath and Miyahama Grand Hotel’s scenic, date-dependent access.

Checked: 2026-09-27

Miyahama Onsen sits on the mainland opposite Miyajima, in Hatsukaichi. Three places publish day-bathing information, but they are not interchangeable. One is a purpose-built bathing facility, one is a small ryokan, and one sells a day visit around its sea-facing outdoor baths. The right choice depends as much on your available time as on the water.

FacilityAdult admissionWhat stands outMain catch
Benimansaku no Yu¥900 weekday planning rateLong hours, multiple pools, sauna, restaurantIts static page still shows an older ¥800 fee; verify special dates
Ryokan Kanzaki¥650 listed adult rateSmall inn, garden, lower priceNo outdoor bath or sauna; date-specific guest restrictions can apply
Miyahama Grand Hotel¥800Rooftop or rock-built outdoor bath, sea viewsDay-use hours and gender allocation change through the week

Benimansaku: the flexible option

This is the easiest place to fit around a day on Miyajima. Bathing is normally open 10 a.m.–10 p.m., with last entry at 9:30 p.m. There are several bath styles, a sauna and cold plunge, plus a restaurant and terrace in the same building.

Dated 2026 notices list a ¥900 weekday adult rate after a May increase, while the standing visitor page still displays ¥800. Treat ¥900 as the current planning figure and check the month’s calendar for weekends or special days.

The facility is about 5 km from Miyajimaguchi by road and has a stop on the Ono Heart Bus. The last departure matters if you stay late.

Ryokan Kanzaki: a lower-cost inn bath, with fewer extras

Kanzaki’s listed adult day-use price is ¥650. The public bath uses Miyahama Onsen water, and the inn’s pages describe a garden and lounge for guests. This is a quieter, more focused bath visit than a large spa complex: there is no outdoor bath and no sauna. The small private bath is explicitly not hot spring water.

The bathing page’s operating hours are not the same as day-use admission. Local visitor information gives an afternoon day-use window, while Miyahama Onsen’s weekly notices have sometimes listed restrictions, including a children’s restriction. Check the notice for your date or call before making the trip, particularly with children.

Miyahama Grand Hotel: choose it for the outdoor bath, not spontaneity

The hotel’s public bath connects to either its rooftop Marumie bath or the rock-built Nozokimi bath. The assignment changes between men and women by date. Adult admission is ¥800, but the daily opening period can be shortened or cancelled; the hotel publishes the current week’s hours and allocations online. Pay in cash.

The private half-open-air bath, Momiji, is sometimes available to day visitors for an additional ¥3,800 on top of admission. The hotel asks guests to enquire about dates and times. This is the option to check if you need a private bath; it is not included in the public admission ticket.

One spring area, different published details

Grand Hotel lists its spring at 22.1°C and pH 8.1; its water is heated, supplemented and filtered through a circulation system. Kanzaki cites an older analysis of Miyahama Onsen No. 2 well: 25.0°C at the source, with pH 7.9 at emergence and 8.1 in the laboratory. Benimansaku identifies a simple weakly radioactive cold spring but does not publish matching figures on its current facility page.

Getting there

All three are in the same small onsen district, near JR Onoura and the Ono Heart Bus stops. Kanzaki says its closest stops, Miyahama and Benimansaku no Yu, are about a two- to three-minute walk away. Benimansaku lists JR Onoura at roughly 2 km by road and a bus stop at the facility. Grand Hotel’s listed station shuttle is tied to overnight guest arrangements, so confirm directly before assuming a day-use ride is available.

From Miyajimaguchi, the district is roughly 5 km by road. If you are travelling by bus, use the current Hatsukaichi City timetable rather than planning around a remembered departure; buses do not run at city-tram frequency. For details on the individual facilities, see the Benimansaku guide, Grand Hotel day-use guide and Kanzaki guide.
