Relax in a free-flowing source-water cold plunge bath in a space filled with Taisho romantic charm

Tokyo Ota City

A popular sento in the Kamata area, featuring a beautiful retro-modern interior inspired by Taisho romantic style. In the tasteful bath area modeled after Dogo Onsen, all tubs use natural hot spring water. The sauna is a compact but properly hot dry sauna, and the cold plunge bath afterward is a luxurious natural mineral spring with free-flowing source water. The soft water flowing from a lion’s mouth creates a soothing experience that makes you want to stay in the bath forever.
