The Tokyo Stock Exchange has today launched the first in a series of improvements to its trading platform following two IT-related closures to the market in as many months. It has dropped Fujitsu, the developer of the crisis-hit system.

The exchange has replaced its trade-clearing system, dropping its traditional IT provider Fujitsu for Hitachi. It has boosted its processing capacity by 25% to five million orders, from the previous limit of four million.
