Number 100 (or #100) is usually given to the competitor the producers think has the best chance to achieve Kanzenseiha, yet #100 has never done it (Nagano Makoto was the closest, coming up 0.11s late in SASUKE 12).
In the 10th, 20th and 30th anniversary competitions, the number given was 1000, 2000 and 3000, respectively.
In SASUKE 18, due to Nagano Makoto's Kanzenseiha, all the competitor were treated as rookies, and a 1200m race was held with the winner getting to choose their number first, however Kato Masafumi chose #77, allowing Kume Ryouta to pick #100.
Number 100 has been worn 15 times by Nagano Makoto, 7 times by Yamada Katsumi, 4 times by Morimoto Yūsuke, 3 times by Akiyama Kazuhiko, twice by Urushihara Yuuji, and once by 5 others, Kawashima Hiroshi, Omori Akira, Kume Ayouta, and Matachi Ryo.
Number 100 has never achieved Kanzenseiha, failing the Final Stage 5 times, the Third Stage 8 times, the Second Stage 7 times, and the First Stage 15 times. Number 100 has been eliminated by time out 14 times, and by falling 21 times.
