TEFL – Suitable way to learn Japanese for skilled work later?

Hi all. I have studied Japanese for a while and was studying towards N3, but realise that my speech particularly was dragging, as there are very few people to language share with in my home country (UK, not london).

I would like to experience living in Japan, however I am an EV Battery Engineer with experience. I've spoken to recruiters and there are jobs, but require N2, which is like to reach in the country with practise and genuine grasp of speaking/listening.

I'm thinking as a bridge, maybe TEFL? But of course it's not a career for me, but could give me good progress in learning the language and then seek another job after maybe a year.

Seeking advice, this could be a bad idea as I might work too much and not have to learn, or maybe people would just suggest the teaching environment is very unpleasant. I have no idea at this stage, just spitballing solutions.

TLDR – Would like to spend time working in Japan, jobs require fluency in my field, would like to become fluent by exposure in Japan via TEFL – Bad idea?
