I want to study aboard to get jobs and get a certificate as well to try and be a Mangaka but trying to figure out options.

I have been studying Japanese since my later middle school years, through I haven't gotten serious at it until 9th grade. Right now I'm 21 years old and I live in Detroit where I don't have many options of getting a certificate Japanese. The community college I go to right now is too far to go there this winter and I'm really looking for options to get a certificate. Through I never took a JLPT test, I think of myself as N4-N3 level.

The reason why I stared is because through originally I thought it would be nice to be there as a tourist but as time went by I took a genuine interest in it's culture and it's nice people and land. It's look like a country that I'll like a lot to live in or at the very least live in for a years. Now I know that Japan also known for some parts not liking foreigners but I'm sure there'll be some people that help me.

Through I'm currently looking for other jobs in Japan besides Mangaka to help me, I'm thinking about studying abroad some time in the next year. Reason why is as I mention earlier there isn't many ways for me to get a certificate in Japanese and it would help me a lot getting to N1 level. As for being a Mangaka is I love the art style and the many ways to draw out scenes along with me liking Japanese culture. Not to mention a story just came onto my head since I was at middle school and I would love to tell it in manga style. Now I'm aware of the cruel hours and how hard it is to get in the industry so I'll probably start off as a webtoon artist but I would love to try to sell my manga work to a more major company if possible.

As for the question itself, I would like to ask what type of Japanese exchange schools to take into? I would like to get in one that last at least a year and somewhere in Fuukoka since I heard the people there is very friendly and cheap to live there. I also live with my mom right now so my options to go in a Japanese class to get a major in Japanese is rather limited so that's why I believe that going aboard would be my best option right now. Also I'm currently trying to get in Associates of Art as well so if there any way I can get that as I'm studying aboard in Japan that'll be great.
