Travaling to japan - poor 19 yr old?

You need a four year degree to work in Japan.You need a round trip ticket to go there.You will be finger printed and have your photo taken when you arrive there.They will also ask why you are there and where will you be staying.You will be arrested and deported when they catch you "bumming around".Working for room and board won't be possible.Most Japanese don't speak English.And a white kid on a skate board will stick out like a sore thumb! Sorry,your idea can't work, period.You're only 19, you can save up your money and do it the right way. The police would arrest you if you try to sleep outside.And eating noodles only will make you sick.BTW,Japanese eat alot more than just sea food.
