Yokohama Onsen Kogane Yu is located in the Totsuka ward of Yokohama, Kanagawa Prefecture. Its sodium-chloride thermal water reaches 41°C (106°F). An indoor bath, an outdoor rotenburo bath and a sauna are accessible here.
Insider tip — Yokohama's deep artesian wells tap ancient marine sediment layers to yield the celebrated kuro-yu — jet-black water high in sodium-chloride and humic compounds from fossilized sea life. Kogane Yu (Golden Bath) is a neighborhood sento faithful to this tradition. The Totsuka district has a quieter, residential Yokohama character far from the tourist bustle of Minato Mirai, making this a genuinely local bathing experience.
