If I apply to a language program in Tokyo, would they possibly be able to help me find job other than teaching English?

I currently only speak English, and I currently hold only a high school diploma. I visited Tokyo a while back, and I really liked it there. I’m not really the type that’s heavily into Japanese culture, and/or anime, but I just genuinely enjoyed being there. Since I’ve left, I always think about it often. I’ve been really contemplating moving abroad there if possible. I’ve found it kind of difficult teaching the language to myself, and thought that maybe studying abroad there would help me get my foot through the door. I’ve also contemplated taking a program online for a bit, but I don’t think that they’d be able to help me find a job there.
