The International Mathematical Union (IMU) was founded on September 20, 1920,
during the International Congress of Mathematicians (ICM) in Strasbourg.
The founding members were 11 countries:
Belgium, Czechoslovakia, France, Greece, Italy, Japan, Poland, Portugal, Serbia, United Kingdom, United States of America.

The present members of Group Ⅴ are:
Brazil, Canada, China, France, Germany, Israel, Italy, Japan, Russia, United Kingdom, United States of America.
The Committee of Mathematical Science of the Science Council of Japan (SCJ) has served as Japan's Committee for Mathematics of Adhering Organization until 2011.
In 2012, Japan's National Committee
for IMU took shape as a subcommittee of the Committee of Mathematical Science of
SCJ
as well as Japan's Committee for Mathematics of Adhering
Organization of the IMU.
