(Corrects to foreign currency-denominated remittance in paragraphs 1, 4)
TOKYO, March 12 (Reuters) - The main banking arm of Mizuho Financial Group said on Friday a hardware glitch at its data centre had caused a delay in foreign currency-denominated remittance for corporate customers, in the fourth system breakdown it has suffered over the past two weeks.
“While we haven’t found a causal relationship among the four recent system failures, we are taking a series of events extremely seriously,” the bank’s Chief Executive Koji Fujiwara told a news conference.
“We will thoroughly look into the hardware and the system operations.”
The hardware problem occurred late on Thursday night and failed to switch to a back-up device, Fujiwara said, resulting in a four-to-five-hour delay in foreign currency-denominated remittance for about 300 corporate clients. The problem has been fixed, but the cause was yet to be identified, he said.
Mizuho Bank suffered a large-scale system breakdown on Feb. 28, affecting 4,318 automated teller machines (ATMs) out of 5,395 nationwide. The bank suffered two minor system glitches at ATMs on March 3 and 7.
Fujiwara has promised to take preventive measures.
