No japanese language skill

I wonder if anyone can help me, I'm curious to go to japan to work for about a short period of time to experience work there.
I have been to Japan a few times, so I'm really familiar with the culture and love it there but sadly my Japanese skills are lacking tremendously.

I have a degree and I have 3 years of digital marketing experience.

I wonder if this can help me at least land a teaching English role for like 2-3 months, not a long time.

Your first hurdle will be what type of visa you have to get?

Easiest wil be a work holiday visa but this only available for certain countries.

Working Visas (many types ) option will require a university degree, work experience etc. and a company that will hire you and sponsor your visa.

Simple explanation on visa types.

So are you from Native English speaking country with 12years English education ? If so then maybe, also company dont really want to to go all the hustle and bustle just to hire a short term employee.
