There are so many cool things like this all over Japan, and only a very small percentage of them get completely run-over with international tourists. Even an hour or two outside of Tokyo, many not-so-hidden treasures like this can be found. And there aren't many tourists at these spots.

Take last year's "Lawson with a view of Mount Fuji" thing. The city had to to take all kinds of counter-measures to international tourists flocking there just to take a photo. Meanwhile, there are dozens more Lawsons in the area with epic views of Mount Fuji in the background, and not a tourist in sight.
