I absolutely loved my stay here!! As a disclaimer, this was my third onsen and first ryokan I visited, and I typically prefer new, glass-heavy hotels to ensure cleanliness of the facilities. Although I was initially hesitant booking Mizunoto due to the old-appearing pictures on their website, I ended up completely loving my entire experience!! The double room in the main building I booked was much bigger than I was expecting (even had a small entry area with a mirror and closet), and things were very clean and well kept! They had many free amenities that were a welcome surprise, including a free shuttle to and from Kowakidani Station, in room snacks, dispenser for coffee/tea, and milk/popsicles/yakult after baths, and even late night ramen. Their hospitality was second to none, and I felt so welcomed by the staff. Both dinner and breakfast are included, with multiple times available. The standout though were their onsens— between the three private baths and the 3-4 baths on each side in each building (they switch men and women sides so you get to experience ~7 public baths in each building), I spent hours in the many different onsens and felt so relaxed! I also received an incredible massage. In addition, the hotel had a great location, only a five minute walk from the buses, which can easily take you down to Lake Aishi, Gora area, and Open Air Museum (the time tables and google were quite reliable). The only thing I would change is about my stay was to stay longer!!
