This guide is a collection of lists. We felt that this was the best way to display information about Japan.
The best place to dive in is the Pro-tips section.
This started as a very simple "guide" to Japan based on the experiences of @seanbonner and myself. We were always being asked various Japanese travel queries by friends. We wanted to make a simple "Hackers Guide To Japan."
Since this is such a HUGE topic - it became unwieldy.
However, in asking people for help, we noticed that everyone has a list.
So, the "Hackers guide to Japan" has turned into a collection of lists that are contributed by ourselves and our friends.
In some cases they are community generated and others they are aggressively proscriptive.
Obviously YMMV.
