On Your Way to Zao — Take a Moment to Unwind

ause for a while in the quiet highlands of Zao.

Nestled at 1,000 meters above sea level, Kogenyu is a small onsen and recovery spot where you can rest, warm up, and reset—naturally.

Whether you’re heading to the mountains, coming back from a hike, or simply exploring the area, it’s the perfect place to slow down and breathe in the fresh mountain air.

🌿 A Simple Way to Unwind

Kogenyu isn’t about doing anything special.

Start with a sauna to gently warm your body,
then soak in the onsen and step outside into the fresh air.

Just that is enough
to leave both your body and mind feeling lighter.

Surrounded by the nature of Zao,
take your time and unwind at your own pace.

A Stop Along the Way

Kogenyu doesn’t have to be the main reason for your trip.

Zao is known for its mountains, skiing, and trekking.
And along the way, there’s a place where you can pause.

After a day outdoors, or in between stops,
a short visit here can be just enough to warm up, unwind, and reset.

Nothing more—
and that’s what makes it feel just right.
