Sira,
I knew what you meant, but just wanted to make sure, as there is a definition for "guarantor" when it comes to spouse visa application. Sorry for seeming to be picky.
To the original poster,
It's fine to ask here on this forum for experiences, but for certain official procedures it might be better to turn to the right authorities :) But the following is what I know.
If you are getting married IN Japan and want to proceed to apply for Spouse visa, you won't have anything to do with Certificate of Eligibility. CoE is something you apply for when you apply for a visa status from outside Japan.
You come into Japan on a Temporary Visitor status (for US citizens, just the passport), then you get married (based on Japanese law).
For the marriage process itself, please refer to:
http://tokyo.usembassy.gov/e/acs/tacs-7114.htmlThen based on that marriage you file an Applicationn for Change of Status of Residence. Once you've turned in all papers needed and get your passport stamped with "application accepted" (I forgot the exact wording, sorry), you can stay in Japan.
This is the procedure of this application for change - please have your wife-to-be read through this. It also provides a link to the list of
supporting documents that she and you need to provide as well:
http://www.moj.go.jp/ONLINE/IMMIGRATION/16-2.htmlI cannot find the "exact equivalent" in English, but this gives the outline (not enough details about the documents needed, though):
http://www.immi-moj.go.jp/english/tetuduki/kanri/shyorui/02.htmlSince you're just getting divorced then getting re-married, note that there *might* be more questions posed about the authenticity of the marriage by Immigration - if you apply from outside Japan, they do seem to ask for photos together, background of how you met, etc., and you *might* get requests like those though you apply from within Japan.
