Owari Onsen Tōkai Center
A big bathhouse in Kanie, just west of Nagoya, open since the 1960s and known among Tōkai-region onsen fans as 'the real thing'. Two of its own springs, one cool and one hot, are blended to bathing temperature and run untouched — no dilution, no recirculation — into both indoor and outdoor baths. The showpiece is a garden-style indoor hall of a scale you would not expect, with pools of various sizes among rocks and greenery. The clear simple spring is soft and leaves you refreshed. Adults ¥700 on weekdays, ¥800 on weekends and holidays; open 13:00–23:00 (last entry 22:30), no closing day apart from occasional maintenance. Soap and shampoo provided; a tatami hall and restaurant on site. About 7 minutes by taxi from Kintetsu Kanie Station or 17 minutes on foot from JR Eiwa Station; 250 free parking spaces. A rare chance at free-flowing source water within 30 minutes of Nagoya Station.
