Masaru was the perfect host. He picked us up from the JR station and dropped us off at the JR station at the end of our stay as well. (Note: we were a family of 7 people so it was no easy task). Also, he made us a fabulous dinner on the first night. It was super delicious and we all enjoyed ourselves immensely. I would definitely go there again!
Note: if you are traveling on a JR Rail Pass, his house is about 8 mins away which makes it super convenient!
