Kansai's largest hot spring theme park "Solaniwa Onsen OSAKA BAY TOWER" A town from the Azuchi-Momoyama era has been transported back in time! Based on the concept, we fuse the Japanese style of the good old days with modern Japanese fashion. In a special space like never before, enjoy a special time by immersing yourself in the ancient times while wearing kimono-style in-house wear, including an open-air natural hot spring bath, footbath, bedrock bath, relaxation, Japanese cuisine, and a rooftop Japanese garden.
