I just received an e-newsletter from Japan-guide announcing the following:
Important notice: On April 19, 2013, ATMs at 7-Eleven stores stopped accepting Mastercard, Maestro and Cirrus cards issued outside of Japan. Similarly, international ATMs across Japan, including postal ATMs, stopped accepting Maestro cards with EMV chips (but continue to accept Marstercard and Cirrus cards and Maestro cards without EMV chips).
This doesn't look good. Anyone has any experience already? It seems like the only option is to use cards without EMV chips at postal ATMs.... BUT don't most cards have EMV chips??
