Sales manager position in Japan

Hello, I have 3 years of experience as an international sales manager, selling hardware (server from Dell and HPE), 27 years old, know 2 languages (do not know Japanese yet).

I do not have a uni degree, instead I have a 3 year blue collar ish degree in digital Information processing (which, as far as I know, does not do much).

Want to move in with my wife, with her on a dependant visa.

I digged around, and I am kind of eligible for an international services visa, but I am not 100% sure, maybe anyone took similar path or in the same boat?

Got any advice?
