Atago Onsen is situated in Goshogawara, Aomori Prefecture. Its iron-rich water reaches 41°C; an indoor bath, rotenburo and sauna round out the facility.
Insider tip — Atago Onsen in the Goshogawara area channels an iron-rich thermal spring into a traditional sento setting popular with the surrounding agricultural community. The copper-tinted water speaks to high iron content that local bathers prize for easing joint stiffness and promoting deep relaxation. The facility is close to the famous Tachineputa festival grounds, making it an excellent pre- or post-festival retreat. A long soak here after a day of sightseeing along the Tsugaru Peninsula is genuinely restorative.
