The setting of this onsen couldn’t be more dramatic: it’s located in a rocky cleft in the seashore of the tiny island Shikine-jima, an island only a few hours’ ride of high-speed jet ferry Seven Islands from Tokyo. The hot spring pools are formed by the seaside rocks. It’s one of those onsen that only works when the tide is right. You can spend a few lovely hours here watching the Pacific rollers crashing on the rocks. And, there are two or three other excellent onsen on the island when you get tired of this one.
In a way of access to the Shikine-jima island, you can take a overnight ship from Tokyo. (Takeshiba Pier near JR Hamamatsu-cho Station) You might also choose the high-speed jet ferry during daytime to the island.
When you wake up in the next morning, the island is already up there. The ship arrives in the port of the Shikine Island at 8 am.
Please hurry up to the best island hot spring "Jinata Onsen" located at another end of the island with your bikes because it is so popular and you had better reach there first.
After going across this tiny island, you'll see the stunning shot up there at the entrance of the trail leading to Jinata Onsen.
You park your Brompton at the parking space and you need to walk down a steep staircase to the hot spring.
When you go over this cleft,
You look at the seashore, where brown hot water spings gushing up from the bottom of the sea and you can bath in the pools comfortably. The hot spring holds a lot of iron in solution. That's why the color is brown. The Jinata hot spring has a long history to cure illness of residents and visitors.
A plenty of earth origin natural hot spring flows into my original bath tub.
The view from the rock bath tub is like this. I enjoyed the bathing experience for an hour in Jinata.
Then, let's go to the next one on another beach.
In a rocky beach of Shikine Island, there is another special hot spring, Funaritto Oku-Oku Onsen, which only emerges during the timing of spring big tide for about an hour each time before being submerged into the sea again.
It means that there are only several chances per year to appear above the sea water. We fortunately met the timing!
You can enjoy bathing here with an excellent ocean view and fresh submarine hot spring bubbling up from the bottom of the seashore only if you are lucky.
After an amazing experience, we hurried to the lunch place.
Before leaving the island, we climbed to the top of the mountain!
