If you read Japanese, this website would be very fun to read.

It's about questions from non-Japanese people. Some of the questions are really funny, and the answers are great.
The questions for example are:
- why do they say "sumimasen" instead of saying "thank you?"
- What is Otaku?
- The country has a lot of money, but why do individuals not have so much?
- The conversation between high school girls does not sounds like Japanese. Do Japanese people really understand it?
- Why do the Japanese ghosts have no legs?
- Are there any Samurai in Japan?
- How can I be a ninja?
Have fun :D
