No. Probably more expensive overall, and not worth the hassle.
However you should probably have some form of backup (credit card, other bank ATM card, prepaid VISA card, etc) rather than relying on ONE plastic card.
Note that at the 7-11 ATM you can only withdraw in units of 10,000yen, and there is a 210yen surcharge for MasterCard (that probably includes Cirrus+Maestro).
At the post office ATM, you can withdraw units of 1000yen, and there is no charge other than what your card issuer charges.
