Super sento / onsen - Ryusenjinoyou. They just reopened a week ago after renovation, everything is brand new and shiny. The place is worth visiting, lots of interesting things: - a sauna where you can pour water yourself. You don't see that often. You pour into a trough, and the water flows through little pipes onto the stones and hisses. - a super cold bath after the sauna. It literally says 超冷水風呂 (super cold water bath). 8 degrees. But regular cold baths are also available. - all kinds of carbonated baths. Sparkling water everywhere, even in the lying-down baths. - a stone throne in the main rotenburo - they say the bath lighting is beautiful in the evening - amazing electric baths! Really high quality massage that goes deep inside. Rare for Kanto.
