I see that you live in Canada. Luckily, Canada and Japan have a Working Holiday program.
Quote:
This program makes it possible for citizens of one country to enter the other primarily for a holiday over an extended period, and also to engage in employment as an incidental aspect of their trip in order to supplement their travel funds.

With this program, you don't need a special skill to get a working visa.
But I strongly recommend learning Japanese as much as you can before you go. You can only obtain this type of visa once, and it's only for 12 months so you don't want to waste your time not being able to communicate when you get there. Finding a job is hard even in your first language, imagine writing a resume, filling out applications and doing interviews in a foreign language. It won't be easy.
Find out everything about this program, read some stories of people who participated in it on the web and see if that's something you really want to do.
