First off, I know you love your wife, but you should also think about what you want. If you really don't want to go to Japan, talk about it with her, instead of just submitting. Obviously if you wife is "sick" of your home country, she won't want to come back anytime soon. Think of all your friends and family, you will have to give up seeing them. Also, your job will obviously be gone. You obviously aren't one of the just-graduated kids who wants to move to Tokyo for [insert reason people like Japan], so I am sure you have already considered that.

Anyhow,your chances of getting anything outside of English teaching are slim to none with no Japanese ability. English Teaching is probably more bearable outside of the major schools like Nova, so you might want to give it another go, it is one of your only options.
