Find Secluded Hot Springs in Japan | Hidden Onsen Map & Rankings
Secluded hot springs (hitou) are onsen tucked away deep in the mountains or in places that are hard to reach, where getting there is part of the reward. On this page you can explore these hidden onsen from across Japan using a map and a list.
From a ranking based on our original 'seclusion score' to regional entry points and frequently asked questions, everything you need to start exploring Japan's secluded hot springs is gathered on one page.
What are secluded hot springs?
A secluded hot spring (hitou) is an onsen that quietly springs up deep in the mountains, in a gorge, or somewhere with poor access. Unlike large, heavily developed onsen resorts, the journey to reach one and the untouched nature surrounding it become part of the experience — they are cherished as onsen where the visit itself holds value.
There is no strict definition, but the term usually refers to lone mountain inns, open-air baths at the end of a hiking trail or a rough forest road, and small lodges that keep serving free-flowing natural spring water. Quietness, water quality, and scenery all combine to create each spring's unique sense of seclusion.
Japan has a long culture of secluded hot springs, protected over the centuries through their ties to healing baths and religious faith. This page introduces such hot springs from across the country alongside our original 'seclusion score' and makes them easy to explore from a map and a list.

Frequently asked questions
What is a secluded hot spring?
A secluded hot spring (hitou) is an onsen that quietly springs up deep in the mountains, in a gorge, or in a place with poor access. Unlike large, developed onsen resorts, the appeal lies in the journey to reach it and the untouched nature around it — it is cherished as a hot spring where the visit itself holds value.
What is the seclusion score?
The seclusion score is our original measure of how secluded a hot spring feels. We rate three axes — access (difficulty to reach), scenery/atmosphere, and onsen value — each from 1 to 5, and express the average as an overall seclusion score ranging from 1 ('Standard') to 5 ('Extremely Secluded').
Are there secluded hot springs that are easy for beginners?
Yes. We recommend starting with spots rated 1 to 2, where you can drive on paved roads right up to the facility. Once you get used to it, you can gradually take on more serious secluded hot springs rated 3 and above that involve mountain roads or some walking.
What is the difference between noyu and secluded hot springs?
Noyu are hot springs that spring up naturally in the wild with no changing rooms or built baths, making them an especially wild type of secluded hot spring. Secluded hot springs also include lone inns and day-use facilities. If you want to search for noyu only, please also use our noyu map page.
