...and are you going to take that monkey of yours with you?
-just kidding.
I'm neither from australia not from japan, but I can tell you that you won't work in japan without speaking japanese. You'll have a tough time. I went to osaka a while ago and even having studied japanese for two years it was really hard to communicate. You leave the airport and the english language disappears alongside with our alphabet.
The people are loveley <nd they really make an effort to help but 90% will not speak or understand english, -even students and high school kids.

thought you might want to consider that.
