He holds the current unofficial world record (100,000 digits) in 16 hours, starting at 9 a.m (16:28 GMT) on October 3, 2006 and having recited up to 83,431 digits by nightfall, stopping with digit number 100,000 at 1:28 a.m. on October 4, 2006. The event was filmed in a public hall in Kisarazu, east of Tokyo, where he had five-minute breaks every two hours to eat onigiri to keep up his energy levels. Even his trips to the toilet were filmed to prove that the exercise was legitimate. Haraguchi's previous world record (83,431), was performed from July 1, 2005 to July 2, 2005. On Pi Day, 2015, he claimed to be able to recite 111,701 digits.

Haraguchi uses a system he developed, which assigns kana symbols to numbers, allowing for the memorization of Pi as a collection of stories. The same system was developed by C.S. Lewis to assign letters from the alphabet to numbers, and creating stories to memorize numbers. This system preceded the system above which Haraguchi developed.
