Mistakes expats make in Japan

I came to japan to marry my gf and live here.  when I left Belgium, my city hall insisted to sign a paper that I leave my address and move to a foreign country.  Everything went well, until I wanted to get my papers to get married, it was not possible to get them, cause my address had to be in Belgium, not here.  So I contacted my city hall, to put my name again in Belgium, but they said the only possibility was to go back to Belgium, just to sign the paper. 

So a hint for everyone.  If you apply for visa by marriage.  wait for removing your address and contact the embassy.

I didn't make any big mistakes, but I regret not having learned the language more than I have. It really is a problem sometimes, but I get by with basics. I worked in language schools and relied on speaking English mainly. I just wished I had learned the Japanese language more. But I have to admit I am not very good at learning Japanese.

my biggest mistake was believing the french educated boss i had about the visa,and also trusting a bunch of businessmen,however my neighbours were brill and the friends i made
there,s a bit of wannabe america in japan too ,that a lot of countries have these days
on the whole though i,d go back in a second i miss the place so much,as my brother said the bad ones are the ones that learned from europe etc
