ABSTRACT
Until 1972, all of the international congresses had been held in major cities of Europe, the United States, and Canada. In both the IUPS Assembly and its Executive Committee, discussion for several decades had frequently taken place of the need to reach out more effectively to psychologists in other parts of the world, but no major decision to hold the international congress elsewhere was made until the Moscow congress in 1966. Moving the 18th congress as far east as Moscow had been a bold but highly successful venture, and the 1966 Assembly unanimously accepted the offer of the Japanese delegation, led by Koji Sato, to hold the 20th congress in Tokyo.
