What should i know about Japan before i go on a business trip there? -

i am going on a business trip to Tokyo Japan. What cutsoms and lifestyles should i know about first? and also, what is there to do there?

They have bad people there. that can snatch away cars and purses and stuff like that. I would be careful. When I went there. A japan man snatched away my wallet which had my money in it. luckily not my credit card. but be careful!
