There is a column of application reasons in the application form, and the scope is not large. You can fill in the couple's "Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan". It's also like not having to submit an application. I did it for my husband last year, but I didn't submit the reason. Only "Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan. /kloc-after 0/month, you will be eligible to move in after passing the examination.

You just need to prepare some necessary materials. For example, you have a work visa, employment certificate, tax payment certificate, marriage certificate and so on. If you apply for a study visa, you should find a physical guarantor, because students have no income after all. If you have a scholarship, a scholarship certificate and an identity guarantor, you'd better find a university professor. If you are a university professor, you only need a job certificate. Otherwise the materials will be very troublesome.

I wish you an early reunion.
