The Executive Committee of ICMI has the great pleasure to announce its recent decision to accept Japan's bid to host The Ninth International Congress on Mathematical Education, ICME-9, in the year 2000. The Congress will take place in Chiba, near Tokyo. The Executive Committee is very happy that Japan has offered to undertake this important and demanding task and wishes to thank the Japanese Invitation Committee for ICME-9, and the involved organisations and individuals, for this initiative and for the impressive preparation of the bid. The Executive Committee is convinced that ICME-9 will be a great success both from a scientific, a social, and a cultural point of view. The Committee is looking forward to collaborating with our Japanese colleagues on this challenging task.
