Questions about marriage in Japan and visa

Hello, I'm from Brazil and I have a long-distance relationship with a Japanese National girl. I know her for about 8 months. We set relationship about 3 months ago. We have met before and we want to marry and stay together. We have lots of photos together, chat history and call history from months ago until today.
I have been looking about the best option in our case, but we have some problems and I will list them:

- I'm 21 years old and she's 28 years old. So age gap of 7 years.
- Probably I can't get a 90 days tourist visa in Brazil but only 30 days tourist visa.

The options for me are:
- Tourist Visa 30 days>Marry in Japan>Apply for the Change of Resident Status to Spouse of Japanese National
- Tourist Visa 30 days>Marry in Japan>Go back to Brazil>Apply for Spouse Visa in Consulate
- If Tourista Visa is rejected* Go to another country to Marry>Apply for Spouse Visa in Consulate

*If you know others option, please let me know.


The questions are:
1) Can I change my resident status in Japan to spouse of japanese national if I entered Japan with 30 days tourist visa?

2) If I marry outside of Brazil and Japan, is it hard to get Spouse Visa in Consulate?

3) Even If I can enter Japan and apply for the change of resident status, will it be hard to prove we're real couple because of age gap or few meetings?

4) Given the option, what option will be easier and take less time?

Thank you so much.

I'll only comment on question 4. Maybe others more knowledgeable than I can help with the others. You will need to prove that you are actually married (documents, photos of the ceremony) AND living together after marriage. I doubt that you can do that within a 30 day tourist visit, so would at least need an extension. 3 months might be more realistic.

1) You can apply for Change of Status.
2) You can apply for Spouse Visa of Japanese National at embassy, as long as you are married legally, have all the relevant documents ready.
3) You'll need to show that your marriage is legal(marriage certificate), and you may need to provide prove/details of your relationship leading up to marriage, photos and emails/message histories.
4)COE-Visa or Change of Status, both have its own merit and demerit.
COE-Visa may take longer time, and with Change of Status you get to stay in Japan if your application is
accepted for process.

Note that either option you choose do not guarantee approval.

One way will be come to Japan on Temporary Visitor/Tourist visa, get married and apply for Change of Status. If accepted, your visa will be extended until your change of status application is decided.

If the immigration do not accept your Change of Status, they may ask you to apply for COE, which then you have to leave Japan before your visa is expired. Once COE is approved and sent to you, you can then apply for Spouse Visa at the embassy.

If your Change of Status is accepted but then not approved, you will need to leave Japan, and may have to wait 6 months before you apply again for Spouse Visa/Status.

I don�ft see any more problems here than a lot of other similar cases. Age gap is irrelevant, seven years is nothing. 40 year olds marry people in their 20s every day in Japan. Few meetings could raise an eyebrow or two but if you have pictures together, communication history, etc. and are legally married then this should be proof enough. I�fve known people to be approved after very few meetings, they only aspect of your relationship they are really looking to judge is whether or not it is legitimate.

Correct me if I'm wrong:
First of all I need to go to Japan or other country to marry her.
After that I can apply for change my status to spousal of japanese national. If they accept my application, my tourist visa is extended until they give me the answer. If they don't accept my application, they can ask me to apply for COE with my wife as sponsor. After this I go back to Brazil and have the COE approved and sent to me, I can apply for the Spouse Visa.
Is it correct?

One question:
If they accept my change of status application but don't approve it in the end, should I apply for COE to try to get the Spousal Visa in my country?
Should I wait 6 months to apply for the Spousal Visa in my country?

Yes, that's about it except

1. If they don't accept my application, they can ask me to apply for COE with my wife as sponsor.
Depending, the immigration have no obligation to suggest/ask you to how to
proceed. They just facilitate/check whatever application you submit. You need to request for it.

2. If they accept my change of status application but don't approve it in the end, should I apply for COE to try to get the Spousal Visa in my country? Should I wait 6 months to apply for the Spousal Visa in my country?
Maybe since it under the same thing. But don't trust me. Double check with the immigration.

Check with embassy and immigration to confirm everything, both you and your future wife.
Marriage procedure in Japan, required documentation for marriage, and subsequently your spouse visa/status application.

So if the deny in the end the change of status, can I still apply for COE while I'm in Japan? Or even outside of Japan with a proxy?

Is there a reason you're avoiding getting married in Brazil? You can get married in Japan of course, provided you have all the documents necessary (you'll want to check with your embassy on what you'll need), but you could also get married in Brazil. I'm confused why option #3 has you going to a different country to get married instead of just getting married in Brazil?

For your second question, I'm not sure, but it's possible you might be questioned on why you didn't get married in either of the countries you reside in. Of course, people go to destination weddings all the time, but they usually still file all the paperwork in the country/ies they reside in.

Also if they deny your change of status of residency, you'll need to leave Japan. Whether you can then apply for a COE (which you do from your HOME country through the Japanese embassy there, NOT Japan; no need for a proxy), you'll want to speak with immigration. It's possible that if they reject your change of status, you cannot apply for the COE either for at least 6 months. But you will want to get a direct answer from immigration for sure.

you can then apply for a COE (which you do from your HOME country through the Japanese embassy there, NOT Japan; no need for a proxy)

No, a CoE application is made with immigration in Japan, it's the visa application that is made at the embassy.
