Nomura Holdings Inc., Japan's biggest securities firm, said Wednesday a technical failure prevented individual customers from trading securities on its online trading system.
The system was fixed and back to normal as of 11:19 a.m., Nomura said on its Web site.
Individual customers couldn't log into their Internet accounts, preventing them from making online trades Wednesday morning, Nomura said in a statement filed to the Tokyo Stock Exchange. Customers were able to trade via phone, the company said.
Tokyo-based Nomura, which had 2.7 million online accounts as of January, said it's still investigating the cause of the failure. The securities firm's 330 automated teller machines were also unavailable during the system failure, according to the statement.
