TOKYO – A computer system glitch caused ATM troubles at the Bank of Tokyo-Mitsubishi UFJ affecting transactions early Saturday.
The trouble began at around 1:17 a.m. Saturday rejecting online and ATM transactions, but the glitch has been fixed by around 9 a.m., the world's largest bank said in a statement.
It said that a hard-disk trouble of the company's host computer may have caused the problem, but the company is still investigating.
Kyodo News agency said that the trouble affected some 21,000 ATMs — 2,000 at bank branches and 19,000 installed at convenience stores — and the bank received about 3,600 reports in which users said they were unable to withdraw cash.
The bank debuted in January as the world's biggest bank by assets following the merger between Mitsubishi Tokyo Financial Group Inc. and UFJ Holdings Inc.
