Are there really used panties in vending machines?
And if so, what do they cost?
No idea, I haven't seen any vending machines like that here.
Are you going to?
No, I'm underaged and I don't want to.
Is the crime rate any higher than America that you've observed?
You don't often hear about crimes here like you do in Utah. Once in a while you hear about some crazy Flash Mober who murdered a ton of people and hid their bodies, other than that, the crime rate seems to be really low. I don't have any statistics to back me up though.
Not that I've seen with the Japanese, though a lot of American military men have been getting into trouble lately in Okinawa. Statistically, Japan has a much lower crime rate than America.
Also, I too have been living in Japan for a while, and can answer questions if the OP wants me to.
Sure, I have a bunch of stuff to do so go right ahead.
