[Asia Economy Reporter Hyunwoo Lee] The Tokyo Stock Exchange, which had come to a halt due to a system failure, resumed trading after one day. The Tokyo Exchange stated that the system failure that occurred on the 1st was identified as a hardware issue, and after replacing the faulty equipment, they confirmed that there were no problems with the trading system.

According to local Japanese media such as NHK, on the 2nd, the Tokyo Stock Exchange under the Japan Exchange Group (JPX) announced that trading of all stocks, which had been suspended all day the previous day, resumed normally from the opening time of 9 a.m. All listed stocks, approximately 3,700 in number, as well as exchange-traded funds (ETFs) and all other securities traded on the Tokyo Exchange, began normal trading. Various indices, including the Nikkei 225 average price, the representative index of the Japanese stock market, and the TOPIX index, which reflects the prices of all stocks in the Tokyo Stock Exchange First Section, are also being calculated normally.

The Tokyo Stock Exchange had suspended trading of all securities throughout the day on the 1st due to a failure in the system that delivers price and market information, and the backup system also failed to operate. As a result, the Sapporo, Nagoya, and Fukuoka Stock Exchanges, which use the same system, were also closed the previous day. This was the first time since November 2005 that all trading on the Tokyo Stock Exchange was halted due to a system failure, and the first time since the current computerized system was introduced in 1999 that trading was suspended for an entire day.

The exchange stated that the system failure was caused by a hardware malfunction, and after replacing the related equipment and confirming that there were no issues with the trading system, they decided to resume trading.
