How hard would it be for me to find a job/get a work visa for me in Japan as a Spanish Second Language Teacher?

Hi. I am finishing my academic studies here in Argentina (Spanish Language and Literature teacher). I've worked as an English Second Language teacher in my home country and as a plain Spanish teacher.

I've always wanted to work as a Spanish Second Language teacher abroad, but I never knew in which country I would do that. For a few years now, Japan has grown on me.

I already speak the language to a JLPT N5 level. I intend to keep studying.

Would I be able to work in japan as an English teacher or a Spanish teacher in some university or language institute? I don't mind the wages too much, I just want to settle somewhere peaceful.

Thanks to anyone reading : )
