Career

Canada began in April 1969 to study physics at the Tohoku University, where he received his bachelor's degree in March 1973. He then went to the University of Tokyo where he received his master's degree in March 1975 and received his PhD in March 1978. He then worked as a research assistant at the Institute of Plasma Physics of Nagoya University. There he held from July 1981 to March 1984 as an assistant professorship. In May 1981, he also received another on Mainframe Center of the University of Tokyo. From June 1984 to August 1985 he guest -actuated a research stay at the University of Cambridge. From October 1987 to March 1988, he taught mathematics at the University of Osaka. From April 1989 to March 1990 he was a visiting researcher at the Nuclear Fusion Institute, University of Hiroshima. From April 1990 to March 1992 he was again assistant professor at the Institute of Plasma Physics and taught the way to September 1992 at the University of Tokyo. In July 1993 he went to the Women's University, Nara, where he taught computer science to March 1994. He then returned to Tokyo, where he was in April 1997 Associate Professor at the mainframe center. In April 1999, received at the Information Technology Center a chair for supercomputing.

Until December 6, 2002, he calculated on a supercomputer (Hitachi SR8000/MPP ) in more than 600 compute hours Pi to about 1.24 trillion decimal places. So he held until 2009 held the record for the decimal place of Pi.
