Solaniwa Onsen is one of the largest hot spring facilities in the Kansai region, located inside Osaka Bay Tower. You can enjoy natural hot springs in an extraordinary space that makes you feel like you've traveled back in time to the Azuchi-Momoyama period.

The "beautiful skin hot spring" that springs from 1,000 meters underground can be enjoyed in a variety of baths, including an open-air bath with a direct flow of hot spring water, a garden bath with a view of the vast Japanese garden, and a carbonated spring. There are also plenty of rock baths and relaxation facilities.

In the rooftop Japanese garden, which is about 3,300 square meters, you can stroll around in a yukata or soak your feet in a foot bath. It is a theme park with photo spots, festivals, and gourmet food, so you can enjoy not only the hot springs but also various other ways to enjoy it.
