Mathematical Society of Japan
In 1877, the organization was established as the Tokyo Sugaku Kaisha. It was re-organized and re-established in its present form in 1946.
Today, the MSJ has more than 5,000 members. They have the opportunity to participate in programs at MSJ meetings which take place in spring and autumn each year. They also have the opportunity to announce their own research at these meetings.
In the context of its 50th anniversary celebrations, the Mathematical Society of Japan established the Takebe Prizes for the encouragement of those who show promise as mathematicians. The award is named after Edo period mathematician Takebe Katahiro (建部賢弘 1664-1739) who is also known as Takebe Kenkō.
