Positive: My husband and I booked two nights at Sanyo-so for our honeymoon. The staff was so hospitable and welcoming. The room that was stayed in was comfortable and clean and the private onsen was perfect! The meals that we had were delicious and the presentation was lovely. There are gardens onsite and it was very peaceful and enjoyable after a few busy days in Tokyo. It was a wonderful and the highlight of our trip to Japan.
Negative: Can’t think of anything we didn’t like.
Summary: Highlight of our trip to Japan!
