Re entry permit

A little bit I think, I am half Asian (not Japanese) so occasionally get asked if I am half Japanese or some people just assume I am half Japanese.
People who have mixed friends I guess will think I am half.

if I improve my Japanese I guess more people will think Im half

 

With about 3 years of residence under your belt maybe you can go to the blow job shops w/o any hassle.

 

blow job shops? Is that what I think it is?

 

I was told anyone in the UK can stay for 3 months or 90days with out a visa is that true?

 

If you think it's exactly what it sounds like, then yes.

Largely true yes, so come visit Japan if you have the money.
It is best to have a return or onward flight out of Japan within the 90day period.

Also criminal records are frowned against - hopefully you don't have one.
I can't remember but on the landing card I think they ask (dont quote me) if you have had any convictions before

"With about 3 years of residence under your belt maybe you can go to the blow job shops w/o any hassle."

Wahoo! Result!

 

If you have any type of conviction, just lie and say no. They will not check unless you're applying for a residence visa. For a 90-day, just go. Unless you were in a famous case (like Russell Brand or Brittany Spears) you're fine.
