You don't need to know Japanese in order to search for jobs here in Japan. Personally I would come here without a job and then look. You can usually find something better that way rather than committing yourself before you arrive.

Of course, the safest option is to have everything done and set for you before you arrive. But really, it's not that hard to do it yourself. Furthermore, you will find you'll get a better deal if you arrive then look.
