Itō Onsen

Itō Onsen Tōkaikan (weekend bathing)

A three-storey wooden former inn built in 1928 on the Matsukawa River, now run by Itō city as a cultural facility and a masterpiece of early-Shōwa architecture. The carved transoms, rooftop lookout and guest rooms where rival carpenters showed off are worth the ¥200 admission alone — but on Saturdays, Sundays and holidays, 11:00–19:00, you can also bathe in the tiled 'large' and 'small' bath halls (¥500 adults including admission; halls swap by gender). The water is Itō's simple spring. Note the baths are closed on weekdays. Seven minutes on foot from Itō Station; combine with the riverside promenade and the old spa quarter opposite — a treat for lovers of retro buildings.

Itō Onsen Wada Jurōjin-no-yu (Wada-yu Kaikan)

The oldest of Itō Onsen's 'Seven Lucky Gods' communal baths, a true locals' bathhouse. The spring is said to have been presented to the third shōgun Tokugawa Iemitsu in the Edo period, and today it runs as the ward-operated Wada-yu Kaikan. The layout is simple — a single indoor bath each for men and women — but the clear, simple-type spring flows in freely and the atmosphere is that of an old-fashioned neighbourhood bath full of regulars. Adults ¥400, children ¥200; open 14:00–22:00, closed Wednesdays (with extra days off in even months — check ahead). Soap and towels are sold, so bring your own. About 15 minutes on foot from JR Itō Station; pair it with the Tōkaikan building and Kinema-dōri street as one stop on the Seven Lucky Gods bath circuit. Parking for 11 cars.
