There are lots of advice about this already on the forum, but I'll just summarise what I know.

It doesn't really matter what A Levels you take. You need a degree to work in Japan. It's unlikely you'll get a job that isn't teaching English, as there are already a competent Japanese people willing to take on the other roles.

However, it's been mentioned recently they possibly would take people such as foreign nurses because Japan has an aging population, should they speak Japanese fluently.
