Trading on the Nagoya Stock Exchange was suspended Friday morning due to a system malfunction, prompting the Financial Services Agency to say it will order all six of the nation's stock exchanges to submit reports on their computer systems.

The order will cover the Tokyo Stock Exchange, the Osaka Securities Exchange, the Nagoya bourse, the Sapporo Securities Exchange and the Fukuoka Stock Exchange as well as the Jasdaq Securities Exchange, the nation's largest market for startup companies.

The decision follows two computer problems this week -- the Nagoya suspension came just days after a system glitch forced the TSE to suspend partial morning trading on Tuesday.
