Japanese mathematician Yasumasa Kanada, who computed trillions of digits for pi, is an IT professor at the University of Tokyo.
Dr. Daisuke Takahashi and Yasumasa Kanada did their analysis of PIat the University of Tokyo, in 1997.Computer Centre, University of TokyoBunkyo-ku Yayoi 2-11-16Tokyo 113 Japanhttp://www.cecm.sfu.ca/~jborwein/Kanada_50b.htmlh
The most decimal places to which pi (p) has been calculated is 1073740000 by Yasumasa Kanada and Yoshiaki Tamura of The university of Tokyo, Japan on 19 Nov 1989 using a Hitac S-820/80E computer.
In recent history (the last decade) most of the records for the calculation of pi to high precision have been performed by Yasumasa Kanada working with his research team at the Information Technology Center of the University of Tokyo. The current record is 1.2411 trillion digits calculated in 2002.

In April 1999, Yasumasa Kanada and Daisuke Takahashi calculated pi to 68.7 billion places. In September 1999 they improved that to just over 206 billion.The current record (in May 2016) is 13.3 trillion.
Professor Yasumasa Kanada and a team of researchers set a new world record by calculating the value of pi to 1.24 trillion places, project team member Makoto Kudo said yesterday. The previous record, set by Kanada in 1999, was 206.158 billion places. This record (above) has been superceeded as algorithms and computational speeds continue to improve On August 17, 2009, Daisuke Takahashi announced that his team had calculated pi to 2.577 trillion places On December 31, 2009, Fabrice Bellard announce he had calculated pi to about 2.700 trillion places.
