Wow, those credentials are amazing. Like MMM said, if you have a master's degree you can get a job. I'm surprised you aren't working at a think tank or something with your abilities, it's really remarkable.

Japanese don't expect foreigners to speak their language like a native speaker, and it sounds like you're already easily fluent enough for most positions, so I think if you want to go, by all means give it a shot. Good luck!
