Hello! My name's Gabriel I'm 18 and I want to live in Japan (for 1-3 years). I wan't to study japonese and Manga Art or Designe in order to improve my comunication skills and to take on my artist carrer. I've been living in Portugal for the past 14 years, so I do own the Portuguese citizenship as well as the brazilian citizenship. My sister is married to a japonese descendent and they've been living in Japan for the past 13 years, I want to know how can I get a work visa or so that allows me to work at a full time job (to earn some money) and to study japonese and Manga Art/ Designe or another way for me to live there with my sister and work and live legally in japan.
Thank you for your attention.
To get a Japanese visa to WORK, first, you will need to finish university and have a degree. That is required in order to apply for the visa, if you don't have a degree, there's a very low chance.
Once you have a degree, you need to find a company who would like to hire you. There are many companies, you need to search, send your resume and such.
It is quite difficult, but not impossible, to find a company who would hire you without interviewing in person. The best is if you could live in Japan for a while with a student visa, and while here, you search for a job.
You can work part-time during your college years in Portugal, save up some money and pay for a year of Japanese course in Tokyo or Osaka. This way you can get a student visa for a while, and find a job while being here.
Once you find a job, the company will sponsor your work visa. With the student visa, you can get a permit at the city hall and work part-time for the company before the work visa is ready. Also, make sure to say to the immigration when you arrive in Japan, that you would like to work part-time. They can make your permit immediately upon arriving in the country as well.
I hope this information helps! Focus and follow your dreams, you can do it!
