Yunohama Open-Air Bath
Time Out says
Located on Niijima, part of the Izu island chain, this open-air bath is themed on the ruins of ancient Rome – for some inexplicable reason. Enjoy mixed bathing in six different hot springs, open around the clock and boasting grand views of the starry sky at night. Best of all, the facility is completely free for all comers.
|Transport:||2 hours and 20 minutes by ferry from Takeshiba Port Teminal. 5-minute walk from Niijima Port|
