A review of the Aenokaze Onsen Ryokan Hotel in Wakura Onsen Japan. Aenokaze is the sister hotel to Kagaya a famous ryokan which is one of the top Japanese onsen ryokan, receiving the "best of" award throughout the past 30 years. And if you look on tripadvisor ratings, Aenokaze is actually rated above Kagaya -- because it has almost the same service, you can use the same onsen, at about half the price!
