Is moving to Japan with a RNCP title enough ? (French diploma and also works in Europe)

I don't have any plan of moving to Japan right now, but I was wondering if in my case it would even be possible in the futur.

Like I said I have a "RNCP title" (bac+3) in France, wich is the equivalent of a three year post high school diploma, I guess ?

I know that having a bachelor’s degree is really important in Japan if you need a work visa, or at least 10 years of experience, and I technically have neither. That’s why I was wondering if anyone has succeeded in obtaining a work visa with that type of diploma.

Maybe someone that is French or/and with that type of diploma ?

Thanks for the help
