In Japan there are many  rules. For example when you get on the train. The train arrived a station then open the door. You should wait for passengers from getting off train then you can get on the train. You didn't eating,  make noisy, talk on your cell phone, of course put a cell phone into silent mode. Here's an interesting rule. When you take an escalator if you be in a hurry you should walk the left side on the escalator. If you didn't in a hurry you take the right side on that. But that rule is Tokyo rule, Osaka is opposite.

    I had been in The U.S. I take on the bus while I surprised, because A man was to singing very louder. But the other passengers didn't mind. Some passengers talked on there cell phone. it was very louder. the other passenger had a lot of things. there were cans, bottles in the cart. There were very dirty, and smell bad. I don't like The U.S transportation.
