I found this out there. It seems funny but it's actually almost bang on on one way to stay in Japan.

? sanity check - why move... http://www.crnjapan.com/prevention/en/p ... riage.html
? inform current employer of intentions
? get letter of recommendation from employer
? if not already finished, search for Japan job.
? pack up things that will go with you to Japan... sell the rest
? get home-country's driver license documents
? get letter from friend that introduced fiance to me
? get phone records showing international calls to fiance
? get passport sized photos of yourself (L4.5 cm x W3.5 cm)
? get bank statement for previous 3 months
? stay with my parents for a week or so -- cheap rent!
? Buy a one-way plane tickets to Japan for fiance and a round-trip for me (have it set for 3months...
? ship things you want to keep to Japan - use fiance's parents' place for temp storage
------
? Verify Sanity check - http://www.crnjapan.com/marriage/en/ & http://www.debito.org/handout.html
? Verify that potiential employer is still interested...
? Arrive in Japan under tourist visa. Fiance is native... so no problems for her. ** be honest with Immigration: tell them you're there to visit friends and to get married!
? stay with fiance

These are only steps for the one planning to marry I wonder if you have a list for someone who's not planning to do this - for example - with just work visa first.

I understand that you can easily get some steps from this guide, but was thinking that separate one would be better.

I will try and put one together. Cheers
