Yudomari Onsen is a magical spot on Yakushima Island, offering a one-of-a-kind hot spring experience. Nestled along the island's southwestern coast, this onsen is right by the sea, with natural rock pools carved out of the volcanic landscape. The water here is naturally heated, reaching around 50 degrees Celsius, perfect for a warm, soothing soak.

One of the most unique features of Yudomari Onsen is its tidal pools. During high tide, the hot spring pools are submerged by the ocean, mixing the mineral-rich hot water with the cold sea. This creates a unique blend of temperatures, making each visit different. Timing is everything, and visiting during low tide ensures you can enjoy the full warmth of the hot spring.

The setting is breathtaking. As you relax in the pools, you’re surrounded by the rugged beauty of the volcanic rocks and the endless view of the ocean. The experience is even more magical at sunset, when the sky explodes in vibrant hues, making the moment unforgettable.

What other travelers are saying about Yudomari Onsen

Small, seaside onsen, only a few minutes away from Hirauchi Kaichu onsen. The 2 onsens couldn't be more different. Yudomari is open 24 hours and is not covered by the rising tide, although it is seaside. The onsen is segregated, the ladies side is the furtherest side from the entrance. It is covered and there are baskets to leave your clothes in. The onsen is in a plastic "tent" is is more protected from the weather. The water isn't super hot but is comfortable to sit in. There are toilets in the car park and the onsen is well sign posted from the main road. You can pay in cash or use a payment app to pay the entrance fee. This is a great place to bathe.

Nice little public Onsen by the sea. Men and women separated by a tarp, covered from the elements. Water wasn’t very hot. ¥300 donation. Toilets and a sink available by the carpark.

Love this place. My friend and I went everyday during our trip as it was close to our guesthouse. Not crowded but some locals come after work. It was perfect after a long day of hiking. Donations expected. Beware it got quite buggy after sunset.

The onsen is outside with a clear tarp structure to protect bathers from the elements and also from view. The water is a little bit warm but that means you can soak for a long time! Don’t go expecting to get a hot bath. I went when it was raining so it was a fun experience just listening to the rain on tarp and rocks outside, and there were not that many people. You can walk down the path past the onsen a little to find smaller pools in the rocks to bathe your feet. These are pretty algae covered though. I think the onsen would look better if it was cleaned more, and if the wood and tarpaulin were all more uniform. The structure looks a little haphazard. There’s also not good storage options for you belongings at the entrance to the bath. I also couldn’t find the place to put my donation! I looked all around the building for the money box and couldn’t find it. Last, I think some kind of window to be able to view the outside ocean would be nice. It seems like a shame to not be able to see the coast while you bathe when you’re so close.

Nice onsen to visit after a day of hiking and a very traditional experience as well. The road leading down is a bit rough, but it’s easy to find. As some have mentioned, there’s a divider for men/women sides of the pool, though the fence is quite low and only really blocks anything when sitting inside the pool. There are buckets at the side to rinse yourself using the onsen water before getting into the pool. The water temperature was warm but not hot, which was quite nice as it let us stay in it for a while without overheating.
