Miyahama Onsen Benimansaku-no-yu

The closest onsen to Miyajima — gazing at Itsukushima across the Ono Strait

Benimansaku-no-yu is a day-bathing facility at Miyahama Onsen in Hatsukaichi, Hiroshima, billing itself “the closest onsen to Miyajima”. It sits on a rise on the shore opposite the island, so the rotenburo and the second-floor restaurant terrace look over the Ono Strait to the ridges of Itsukushima, and it is ten minutes by car from Miyajimaguchi — the perfect place to rest legs tired from the shrine and the island’s hills. The name comes from the benimansaku (Disanthus cercidifolius), a tree that turns crimson in autumn and is a Hiroshima natural monument; the Ono stand is rare nationwide. Renovated and reopened on 27 April 2026, the facility has gender-separated indoor baths (hot, tepid, jet), a seaward open-air rock bath and pot tubs, plus sauna and cold plunge. The water is Miyahama’s simple weakly radioactive cold mineral spring (radon, source about 26 °C), heated and soft. Weekday admission is ¥800 with soap, shampoo and dryers included; towels are sold or rented. The 2F restaurant Yuya Wataya is known for set meals of Seto Inland Sea produce — Hiroshima oysters, conger eel — and a popular carrot cake, and bath-plus-meal vouchers (from ¥1,150) are sold on Jalan. Closed the third Tuesday of each month, open 10:00–22:00. It is 22 minutes on foot or 5 by taxi from JR Onoura Station, with a bus stop at the door, though most visitors drive from Miyajimaguchi or central Hiroshima. Hiroshima has few hot springs, so if you want to add an onsen to a Miyajima trip, this is effectively the first choice.

Tips & cautions

- 10:00–22:00 (last entry 21:30); closed the third Tuesday each month (next day if a holiday). Check the official site’s closure notices for extra days.

- Weekend/holiday surcharge — weekdays are cheaper. Free member card saves ¥50.

- Towels not included — sold ¥150, rented ¥120.

- No large rest hall — eat at the 2F restaurant (11:00–21:00, last order 20:30).

- Tattoos: a super-sento-style facility with no confirmed policy — ask at the desk.

- Classic plan: leave Miyajima on a late ferry, bathe here, then on to Hiroshima. The Hiroden tram does not serve Onoura (JR only).

- With radon water, inhaling is key to the benefits — breathe slowly in the sauna and indoor bath.

- The open-air rock bath is occasionally out of service (pump faults) — see their Instagram notices.
