What this is
Club Inner Spa is a small mixed bathing community in Japan.
We are not a public tour, and not open to everyone.
This is a carefully curated space built on trust, respect, and quiet connection.
If you are simply looking for sightseeing or entertainment,
this may not be the right place.
What you can experience
We visit traditional mixed onsen (hot springs), often in natural outdoor settings.
It is not about activities or attractions.
It is about sharing a calm and respectful atmosphere in the water.
- Quiet time in nature
- Small group interaction
- A different kind of connection, beyond words
Important notes
This is very important.
- This is not a sexual service or activity
- We do not accept disruptive or disrespectful behavior
- Respect for women’s comfort and safety is our highest priority
If you cannot fully understand or respect this,
please do not apply.
Who it’s for
- Women and couples are most welcome
- Solo male participants are accepted only in limited cases
We carefully consider each request to maintain the atmosphere of the group.
Some of our members are comfortable speaking English,
so you will not be alone in communication.
How it works
- We usually meet on-site (Gunma area and nearby regions)
- Most visits are day trips
- Group size is small (around 3–6 people)
We usually spend around 1–2 hours together in one onsen,
depending on the conditions and the atmosphere of the day.
Details will be shared after initial contact.
Fee
- Experience fee: ¥10000
- Please cover your own transportation, onsen fees, meals, something to drink, etc.
This fee is mainly for carefully selecting the most suitable onsen for you,
based on your preferences, experience level, weather, and expected crowd conditions.
This experience is not a guided tour, but a shared and natural way of spending time together.
We usually meet directly at the location, and do not arrange trips from Tokyo.
Pickup from Jomo-Kogen Station may be possible (+¥2000).
Contact
If you feel aligned with this space,

Please tell us a bit about yourself and what brings you here,
and let us know your travel plan (dates, area, etc.) if possible.
