Horai Onsen is set in Tennoji, an Osaka district known for its temple and observation tower. Sodium-chloride thermal water flows at 41°C, feeding an indoor bath, an outdoor rotenburo, and a sauna.
Insider tip — Horai Onsen sits in Osaka's Tennoji district — home to Shitennoji Temple (593 AD, one of Japan's oldest Buddhist temples, founded by Prince Shotoku), the towering Abeno Harukas (300 m, Japan's tallest skyscraper), and the vibrant retro Shinsekai entertainment district with its iconic Tsutenkaku Tower. Tennoji has undergone massive regeneration while retaining its authentic Osaka shitamachi (old downtown) soul.
