You will not be able to use the Tokyo Mitsubish UFJ Bank ATMs will from July 5 (17:00) to July 7 (7:00). This applies across the board. You will not even be able to use the ATMs at convenience stores to get money from Tokyo Mitsubish UFJ Bank accounts. The reason given is the complication of integrating Tokyo Mitsubish Bank and UFJ banking systems. So, if you have an account there and need money for the weekend, then do it fast!
