So.. I notice when people say "please answer".. that nobody answers them

When it comes to getting a visa or job in Japan you can apply a simple test to it to see what your chances are.

Ask yourself if there are Japanese people who can do the job as well or better than you can.

If a Japanese company can employ a Japanese person to do the job - they will.

Foreigners are lots of hassle for Japanese companies (language and culture issues) so they wont employ you unless they have to.
