Find Real Onsen Quality. Gensen Kakenagashi

The town of Ito boasts the 4th largest volume of its natural Onsen water in the country.
Our fresh & pristine Onsen water provided directly from our own sources is continuously overflowing from bathtubs for 24h/365days. 

What's Gensen Kakenagashi?

It literally means "Natural hot spring water from the original source continuously overflowing".

Our onsen temperature is controlled by mixing two natural spring sources in different temperature.
Absolutely no water is pumped from a tap into the tab.

Overflown spring water goes straight into the drain 24/7.

You won't be disapointed with smell like a swimming pool because not circulated, non-filtered 100% pure onsen water needs NO sterilization process by chroline.

It is told that less than 5% of thousands of onsens in Japan are 100% pure Gensen Kakenagashi.

It's just 90 min. away from Tokyo and your JR pass covers all the way. 
Our super friendly staff will welcome you!
