"Wear your shoes, those rocks are tough.
What a delightful onsen though. I found the temperature to be perfect, although there did seen to be a jet of extremely hot water coming out through the wall, so beware of hot spots.
The view was superb. The mosquitoes did arrive as the sun was setting though. I wish I had brought some mozzie coils.
Highly recommended."

"We weren't sure where we were heading, but once we found it, it was an unexpected delight. An onsen right on the beach! The temperature is perfect, but be careful near the west wall as some very hot water seeps through."
Doron Houminer
"Was sad. We had a hard time finding the onsen. Then we realized it was completely covered with stones and kelp, no way to enter. You can only feel the heat with your legs when you stand nearby"

The Aidomari Onsen Experience
However, the experience comes with its own set of challenges. The onsen can be difficult to find, often obscured by rocks and kelp, and some travelers have noted that very hot water seeps through the west wall, requiring caution. As the sun sets, mosquitoes can also become a nuisance, so bringing repellent is advised.
It's important to note that there are reports suggesting the onsen may no longer be accessible as of late 2025, having been disassembled and filled in. Always check for the most current local information before planning your visit to this potentially ephemeral natural wonder.
Navigating Rausu Beach
Visitors should be prepared for the possibility that the onsen itself might be covered by rocks and kelp, requiring a bit of searching to locate. This natural camouflage adds to the 'hidden gem' feel but can also lead to frustration if not anticipated.
While the beach setting offers stunning scenery, it's also a natural environment. Be aware of the changing conditions, especially as dusk approaches, when mosquitoes may become active.
