im with mitsui and its about the same price.
but iv found that if you have a friend or someone who wants something from japan worth a bit, ie wheels or something like that, i buy that here with your own yen and send it to them and then they deposit the correct amount of cash into your bank account in aust. this way you get a good rate and dont pay any bank fees for the transfer and even make a bit out of it for doing them a favour
