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.
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.
An outdoor traditional onsen by the sea which is separated for men/women by a small wooden fence. The pools are quite small and we went near sunset and the men's side was quite busy but the women's side was empty.
The pool on the men's side could fit maybe 8-10 people at a stretch but it is definitely a traditional Japanese experience! Everyone was very helpful to guide me on what to do and would recommend going around sunset if you can for some lovely views.
A 200 yen per person donation can be left near the entrance and there are toilets and changing rooms before you enter the onsen itself.
It is a bit intimidating if it's busy but well worth it for the experience I thought!
