The Tokyo Stock Exchange said Tuesday it has canceled the planned listing of Nomura Research Institute Ltd. due to the deteriorated international investment climate following last week's terrorist attacks in the United States.

NRI, the economic research arm of Nomura Securities Co., was slated to be listed on the TSE's first section on Oct. 2. The cancellation follows NRI's decision not to make an initial public offering as active purchases, particularly by U.S. institutional investors, cannot be expected in light of unfavorable international financial market conditions.

NRI said it intends to apply for listing again when the market regains stability.
