I came here on a Wednesday afternoon. It's one of the best onsens in Nagoya. It's good for several reason: first, it's conveniently situated at Sanno Kintetsu station ( 近鉄山王駅), just a three-minute walk to take you there. You could enjoy 岩盤浴 (がんばんよく) on top of 温泉 (おんせん) plus you got gaming machines (e.g. slot machines), hair cutting, Thai massage, facial treatment, ... the list of additional services could go on and on and on. That said, if compared with Canal Resort, it would still lose. But I do think it had an edge over Nagashima Onsen ( 長島温泉) in that it was much more accessible. There should have been one caveat: remember to bring along everything you'd need, coz there was few, if at all, free stuffs here. You would have to buy towel from vending machine if you forgot to bring your own. You'd get free shampoo and body free for free, though.
