Kitagata Onsen Shiki no Sato (Shichisai no Yu), in Takeo, Saga Prefecture, offers sodium-chloride thermal water at 41°C, with an indoor bath, an open-air outdoor bath (rotenburo) and a sauna.
Insider tip — Shichisai no Yu at Kitagata sits near Takeo City, Saga, where the Takeo Onsen hot spring district has been drawing bathers for over 1,300 years — a longevity confirmed by historical records that include visits from Toyotomi Hideyoshi during his Korean campaign preparations in 1592. The magnificent 1915 Takeo Onsen Gate, a vermilion Chinese-palace-style gate designed by architect Tatsuno Kingo who also created Tokyo Station, stands as the most photographed symbol of this historic Saga spa town.
