Below are links to sites I found helpful during the research for our trip. I didn’t use every single one of them, because there is just way too much information out there and we only had a week, but thought it might be useful to share them. And if I can save you some time on the research, so much the better!
Japan-Guide.com- the is one of the best resources for all things related to traveling in Japan. The website has a lot going on visually, but search through it and there is a lot of depth there.
