[Not Just Upwelling from the Ground] Okutsuso, Okutsu Onsen

Do you know what are hot springs upwelling from the ground?

These are premium hot springs where you can enjoy extremely fresh water, because sources of the spring are located directly at the bottom of tubs.

Okayama prefecture is famous for having such springs, so I stayed in a Ryokan “Okutsuso.”

However, the enchantment of the inn was not just the hot spring upwelling from the ground.

Famous Kagi Yu

It is said that a famous print maker, Shiko Munakata loved the place.

I went through the gorgeous entrance, which played important role in creating the atmosphere of the small spa city.

It is a characteristic structure, which you need to go down from the ground-floor entrance to get to bathrooms.

Kagi Yu

Here is the famous “Kagi Yu” where a local lord had occupied for a long time and prohibited common people from entering.

Look at inside the tub.

The water is extremely transparent and you can find rolling of the rocky bottom quite clearly.

From cracks of the rocks, the spring is actually upwelling.

Tachi Yu
This small tub named “Tachi Yu.”

The water is also upwelling from below but the tub is as deep as 50 inches.

These are available for men and women on a rotating basis.

The water temperature is moderate as 108 degrees.

The nature of the spring does not have notable characteristic but it has slight mineral odor.

Izumi No Yu

Here is a private tub named “Izumi No Yu.”

Although it is so small and located underground, you can see a lot of effort in the renovation especially around lightings so that it creates comfortable atmosphere.

Not Just Upwelling from the Ground

The most favorite bathroom is the private pool, Kawa No Yu” (River Spring in English) which is, surprisingly not a spring upwelling from the ground.

Kawa No Yu

The same water as “Kagi Yu” is piped and the surface of the water is located on the same level of windows.

I opened the windows; a freshening breeze from the river went through the bathroom…

Then I realized the importance of believing in my five senses, not excessively pursuing hot springs upwelling from the ground as a hot spring maniac.

After so long bath time, I finally had the dinner.



Masterpiece, abalones for a hot pot.

It was not just delicious, but also memorable dinner.


😆 Pros

Precisely because the nature of the water is not characteristic, the freshness is being strongly emphasized

This is also an extraordinary clear hot spring upwelling from the ground, but the water temperature is warm.

From cracks of the beautiful blue rocks, the water is upwelling with bubbles.
