ふるさと体験ビレッジふるさとの湯
Miyakejima used to have many onsen, but after two eruptions they all disappeared, and this is the one new one that recently reopened. 500 yen, standard shower with standing showers. Two baths — a large warm outdoor one, feels like 36-37, closed in winter, and an indoor one at 40, a bit smaller. Water is brownish-clear, no smell. Overall pleasant. Outside the ocean view is only visible if you stand up, and there's nowhere to really sit. From inside the ocean is visible through the glass. Of all the onsen on the island, I recommend this one, because it's the only one.
