Running in an intercollegiate meet, the 21-year-old Kiryu took .02 seconds off the Japanese national record set by Koji Ito in 1998.
Kiryu was a member of Japan's silver medal-winning men's 4x100 relay team at the 2016 Rio Olympics.
In 2013, Kiryu ran 10.01 seconds at the Oda Memorial meet in Hiroshima, but the IAAF later rejected the time as an official record due to the use of unapproved wind-speed measurement equipment on the track.
