On the 20th, Mizuho Financial Group was unable to make transactions such as transfers at stores nationwide, causing the fifth system failure.
The issue is how to thoroughly prevent recurrence and restore trust due to a failure in the midst of a comprehensive system inspection.
Due to the system failure of Mizuho Bank this time, about 500 stores nationwide, including Mizuho Trust & Banking Group, were unable to make transactions such as transfers and deposits at the counter from the opening of business on the 20th to around noon.
Mizuho Bank was in the midst of conducting a comprehensive system inspection in response to four system failures that occurred in less than two weeks from February to March.
This time, unlike the part where the failure occurred so far, the device that connects the so-called main system and the terminal of the store failed, and the backup function did not work properly, so it took time to recover. ..
Mizuho Financial Group President Tatsufumi Sakai said at a press conference on the 20th, "I would like to take a stance of never causing a system failure. In the unlikely event that a failure occurs, we will create a system to minimize the impact on customers. I want to. "
However, since the detailed cause of this failure has not yet been identified, the issue is how to thoroughly prevent recurrence and restore trust.
