The Tokyo Stock Exchange (TSE) hereby announces that it has decided to launch "arrowhead", the new equity/CB trading system held to the world's highest standards of speed and reliability, on Monday, January 4, 2010 as initially planned. This is in line with the TSE's previous announcement that it will make the final decision of the system launch upon implimenting the final transition operation.

"arrowhead" is the next trading system developed by the TSE for the next generation cash market in order to meet the needs of investors such as high speed order placement and execution processing and to respond to reductions in sizes of orders and rapid increases in the number of transactions. The new system is used for auction trading of stocks and CBs, and supports the Tokyo Market as an exchange system of the highest global standard for low latency, high reliability, and scalability .
