Full Description

Solaniwa Onsen OSAKA BAY TOWER is more than just a hot spring—it’s a cultural sanctuary. Inspired by the elegance of Japan’s Edo era, this onsen recreates a traditional ryokan village experience while offering modern amenities and comfort.

Begin your visit by changing into a comfortable yukata robe and stepping into the peaceful ambiance of the Tenku Garden—a vast rooftop oasis with waterfalls, footbaths, over 1,000 torii gates, and panoramic seasonal views. It’s a perfect space for strolling, taking photos, or meeting companions before or after your bath.

Inside the onsen area, enjoy the healing waters of “Bijin no Yu” (Beautiful Skin Hot Spring)—a mildly alkaline spring known for leaving skin soft and refreshed. Choose from nine different bath styles, including outdoor stone baths, a carbonated spa, and fragrant herbal baths.

Enhance your visit with a sauna session or body scrub, and unwind in the stylish rest areas or café lounges. With an atmosphere that blends tradition and tranquility, Solaniwa Onsen is perfect for a few hours of relaxation or a full-day retreat.
