Solaniwa Onsen

Solaniwa Onsen baths

The “Clear Skin Bath” is a natural hot spring whose slightly alkalized waters flow up from a source 1,000 meters below the earth.

Be it the open-air bath with its fresh water bursting forth from the subterranean source, or the garden-viewing bath that looks down on our massive garden, or the carbonated spring or special seasonal bath, we’ve got no end of baths—not to mention saunas and scrub-down areas—for you to choose from.

You can even reserve a private open-air bath for between two and six people to enjoy a more luxurious experience.

A place where you can wash away the day’s frustrations and face tomorrow afresh: that is the ideal behind Solaniwa Onsen baths!

Experience Japan’s Azuchi-Momoyama period!

With the theme of ""Going back in time to Azuchi-Momoyama period (1573 - 1603) !"", Solaniwa Onsen unifies ancient Japan and modern days. 
Solaniwa Onsen OSAKA BAY TOWER is unlike any other place where you can find baths filled with natural hot spring, footbath at an enormous rooftop garden, bedrock saunas, relaxation treatments, Japanese food and sweets etc. Wear Yukata, which  you can borrow for free and enjoy Solaniwa Onsen in the way that best suits you!

Combining beautician and healer, that is our promise.

Bedrock sauna warms  the body from the core with the far-infrared rays of a dry sauna, and brings upon you the effects of health, beauty, and healing by sweating out from your deepest core. Also, the relaxation salon at Solaniwa provides close to 30 services such as traditional Japanese body care, scrub-down, cupping and so mcuh more.
