Namioka Ekimae Onsen, near Namioka station, Aomori prefecture, draws iron-rich water from a spring at 41°C (pH 6.3). An indoor bath, an outdoor rotenburo and a sauna complete the bathhouse.
Insider tip — Namioka Ekimae Onsen sits just steps from Namioka Station, making it the natural first stop for travelers arriving by train along the Ou Main Line. The iron-rich water turns the bath a warm amber hue and imparts a light mineral tang. The station-front setting draws a lively mix of commuters, day-trippers, and curious visitors. A short walk leads to the historic castle ruins of Namioka, rewarding those who combine sightseeing with bathing.
