The CI Techno Science subsidiary of the giant trading house C Itoh & Co is to develop financial dealing systems in conjunction with Sun Microsystems and outside software houses: its new Financial Engineering Systems division starts out with a staff of 10 people; CI Techno Science also sponsored a Sun Applications Fair in Tokyo on July 11 and 12, which involved a number of foreign companies already active in the Japanese market, such as Thorn EMI Software Sciences and Reuters Holdings Plc, and others such as Intersec Research Corp, which although active in marketing performance analysis systems to Japanese fund managers, has not yet introduced its InterAccount system onto the Japanese market.
