Fujitsu head cut salary by 50% for failure on Tokyo Exchange

In early December 2020, it became known about the reduction in the salary of FujitsuTakahito Tokita President by 50% for a period of four months. This decision was made after a large-scale failure occurred on October 1, 2020 in the computer system of the Tokyo Stock Exchange, which uses the company's equipment. More details here.

The dismissal of Koichiro Miyahara after the largest IT failure in the history of the exchange

At the end of November 2020, it became known that the president of the Tokyo Exchange (TSE) Koichiro Miyahara is resigning. By his decision, Miyahara intends to demonstrate responsibility for the technical failure, which provoked the shutdown of trading on the exchange for the whole day on October 1, 2020. More details here.

Shutdown due to IT hardware failure in use since 1999

In early October 2020, the Tokyo Stock Exchange experienced the most serious malfunction in its history. On Thursday, October 1, trading was discontinued all day due to a malfunction of a computer system developed by the exchange in collaboration with Fujitsu. Although no final explanation has yet been provided, it is assumed that the termination of the system was not associated with a hacker attack.

The exchange reported that the failure was due to problems in the Arrowhead system, and asked Fujitsu to investigate the equipment involved. But at a hastily organized press conference to explain the events of the day, officials of the Tokyo Stock Exchange said that it was not equipment suppliers, but the operators themselves who were to blame for the problem. The Exchange is not considering damages from Fujitsu.

Tokyo Exchange completely shut down due to a failure of IT equipment used since 1999

All responsibility lies with us, "said Koichiro Miyahara, CEO of the exchange. - Fujitsu is just a supplier of equipment.

Fujitsu spokesman Takeo Tanaka said the company is ready to work with the exchange to prevent further problems.

We apologize for any inconvenience caused to interested parties due to the failure of our equipment, "he said.

The Arrowhead system, used since 1999, withstood a powerful earthquake and tsunami that hit northeast Japan on March 11, 2011. In buildings in Tokyo, a strong shaking was felt, but trading on the exchange was not interrupted. However, a computer failure in 2012 stopped trading in securities, and due to a systemic error in the same year, derivatives trading stopped for almost an hour. In 2015, Fujitsu and the Tokyo Exchange began updating computer systems to ensure reliable uninterrupted operation of the exchange, which seriously affects global markets. Among the changes implemented then was a new modular approach that allows you to disable faulty servers and redirect their tasks without losing data.^[1]
