Kei and Kotaro were just wonderful hosts. They made our stay very comfortable and pleasant. Even though they had a tough schedule with work, they arranged a welcome dinner, not to mention breakfast every morning. We made friends and since they are very interested in connecting with people from all over the world, we had a lot of stuff to talk and laugh about. The accomodation is perfectly fine for a couple and easily accessible on JR lines. I strongly recommend staying at KeroKero!
