It took Akira Haraguchi 16 hours to recite π to 100,000 digits from memory earlier this month. This would supercede fellow Japanese Hiroyuki Goto’s official Guinness Book of Record of 42,195 digits set in 1995. Mr. Haraguchi is not a novice at this. His current feat also bypasses his own personal record of 83,431 set also in 1995, but his previous event was never entered in the Guinness Book.
What I am aiming at is not just memorizing figures, I am thrilled by seeking a story in pi. - Akira Haraguchi
During the 16 hours, all of Mr. Haraguchi’s activities, including his bathroom breaks, were videotaped for evidence for verification to the Guinness Book of Records.
