Insider tip — Kasukabe Onsen Yuraku no Sato draws dark iron-rich water from the deep Kanto sedimentary basin beneath Kasukabe, a commuter city northeast of Tokyo famous as the setting of the Crayon Shin-chan anime. The rich mineral-black bath water is a striking contrast to the typical clear city sento, and regulars swear by its restorative qualities for tired office workers. Kasukabe's suburban location makes this an easy evening escape from downtown Tokyo. The dark waters are rich in humic acids alongside iron minerals, a feature of Kanto's ancient peat layers.
