The Tokyo Stock Exchange suffered its biggest system glitch in six years Thursday, temporarily suspending trade of 241 stocks and other financial instruments for more than three hours.

The TSE detected errors and suspended operations of its arrowhead system before the day's opening at 9 a.m. Full trading started at the end of the normal lunch break at 12:30 p.m.

It was the bourse's first major system trouble since the fast data-processing arrowhead system created by Fujitsu Ltd. was introduced in January 2010.
