If you want to apply for a family visa, first of all, it depends on what kind of visa your boyfriend got when studying in Japan, and the validity period is several years. The visa for studying abroad is usually signed once every two years and will be renewed when it expires. There is also the need to notarize the marriage certificate after the application, so that it can be used when submitting materials in the future. Also, your husband should provide financial proof that he has the ability to support you. This seems to be how much money he wants in his Japanese passbook. When these three conditions are met, success is possible.

About "living at home", it is the so-called accompanying reading. The first time I went to Japan, I went with my husband and got this visa, which is valid for two years. But one year after I arrived in Japan, I took the entrance exam. After I entered the school, I changed my visa to "study abroad". From the day I changed my visa, I had a two-year study visa.

"Family stagnation" can only work, and you need to go to the local "Immigration Bureau" in your Japanese area to apply for a "work permit", which is a work permit. So you can work. As for your "not manual labor", it's a bit difficult. Do you think the cashier in the supermarket is manual labor? Well, I have friends who are doing this job, and they are also very tired. Another prerequisite for a job is that you have to pass the Japanese exam. Only if there is no problem in communication. Besides, seeing that you are a master, it would be a pity if you went to Japan to work with me. I suggest you study for a doctor or something. In this way, you can also work while studying and find a job after graduation. If you want to go to school, you need to notarize the domestic academic degree certificate, which will be used when you enter school.
