Int. ATM Withdrawls w. Japanese Banks

I'm returning home to Australia but I need to be able access my Japanese savings account with either Mitsubishi-UFJ or Mitsui Sumitiomo Bank.
If I apply for an international ATM card with my Japanese bank, does anyone know how much each international withdrawl will cost?
Thanks so much!

First of all, you Japanese banks can give you the answer how much they charge for international withdrawals, this will be the major part of the international withdrawal costs. Second of all, you'll need to ask them if you can access your saving accounts from abroad; quite often you can only withdraw money from your chequeing account.
