I am researching a rather mysterious case related to the IAM WMC memory competition in 2019. There is a Japanese contestant named Tsujikubo Koza, born in 2006, who is said to have achieved a very high score of 6621 in the 30-Minute Binary event, surpassing the world record at that time.
However, when I searched on the official IAM website, as well as recaps and related news articles, I could not find any name or data about this contestant. Furthermore, I suspect that the screenshot of the IAM profile with contestant ID 10623 (allegedly belonging to Tsujikubo Koza) may have been forged or photốthopped.
The contestant’s side claims that they requested IAM to delete their data under GDPR regulations for personal safety reasons, and that this request was made after 2024. Is this possible? And if so, then the information about this score and achievement must have existed and been known by the community from 2019 until before the deletion — that is, for about 4 to 5 years. So why is there no one or no source mentioning this achievement during that period?
I would like to ask if anyone in the community knows more about this case, or has official information from IAM, or has heard any related news? Thank you all very much!
Yup, fake. None of those stats (name, ID number, binary record…) exists in the IAM page. I don’t know why that person posted that on YouTube, but it’s forged.
This girl is a YouTuber who claims to be Japanese, but she and her family recently moved to Vietnam to live and study. She frequently goes on YouTube to boast about absurd personal achievements, such as being able to memorize 40 random digits in 0.2 seconds - yes, you read that right, 0.2 seconds. Memorizing 20 random world events + year within just one second. Remembering 1.5 million digits of pi. Having read and memorized hundreds of books and academic materials from various countries. Winning first prize at WMC 2019… The profile photo and the link to her YouTube channel mentioned above are just some of the things she posted as “evidence” for her claims.
The name (in a darker font) appears less blurry than the rest of the text, so the image may have been edited.
An archived version of that competition page from September 27, 2019 has the same list of competitors as the current version, so it doesn’t look like anyone was deleted from the list since then. There are two competitors from Japan listed, but the names are different and their scores for 30-Minute Binary were 2142 and 1770. The best score for that event was 5070.
