The need for teaching English in Japan is real! I ran around Tokyo for a month and didn't really run into anyone that would speak English. I went to just explore, live in some arcades in Akihabara, etc. so I wasn't too worried, it all worked out! But I pretty much had zero conversations.

If people can speak any English, they're super shy about it. Definitely a fascinating and unique corner of the globe, possibly my favorite.
