Shin Sedai (新世代) literally New Generation or Shin Sei (新星) literally New Star, are a group of young, largely unknown competitors who have emerged as some of the strongest and most successful athletes in the Shin-SASUKE era up until the present. The Shin Sedai are mostly made up of SASUKE Trial Qualifers, many of whom train non-stop for SASUKE on homemade replicas of the obstacles. Like the SASUKE All-Stars, most of the members are made up of ordinary people instead of professional athletes. While there are only two official members by TBS, several other people have been grouped under this name by the announcers. Recently, TBS have hyped up the Shin Sedai and SASUKE All-Stars as two rivaling groups of competitors.


While many of the members are still in high school and college, others have been trying to compete since 2003 and SASUKE 11 with the Monkey Bars event. Many of the older members, including the leader Urushihara Yuuji, failed many times over the span of several years before finally getting to compete at SASUKE. Nagasaki Shunsuke first competed in SASUKE 14 and the first people to be considered as a Shin Sedai in SASUKE 17.


The Shin Sedai emerged into the spotlight in SASUKE 22. While many of the members had competed before this tournament, this was the tournament where the Shin Sedai proved they could not only clear the First Stage but also make deep into the course and carry the show. At the same time, all of the All-Stars (for the second time in history, and the second time in four tournaments) failed the First Stage. This opened the door for some new people to excel. Before this, the All-Stars had dominated and one of the six members made it the furthest out of the 100 in 14 out of the first 21 tournaments.

The two new stars to perform well were Kanno Hitoshi and Urushihara Yuuji both competing for their second time. Kanno and Urushihara matched and went past Takeda Toshihiro's and Nagano Makoto's runs from SASUKE 21. Kanno, made it past the Shin-Cliffhanger which only Takeda and Nagano had beaten the tournament before and even went farther than Takeda before getting disqualified on the Spider Flip. Urushihara went even further. He beat the Gliding Ring which Nagano failed in SASUKE 21 and was the first one to clear the Shin-SASUKE Third Stage after Nagano's kanzenseiha in SASUKE 17. There, he came inches from the goal.

Over the next two tournaments, the group consistently did well with several of them clearing each tournament. Urushihara, who had made it to the Final Stage in SASUKE 22, made it back for a second time in SASUKE 24. This time, he cleared the Final Stage with 3.57 seconds left, becoming the third person to achieve kanzenseiha. He was officially named the leader of the Shin Sedai. After that, he went on to clear the Final Stage in SASUKE 27, with 6.71 seconds left, becoming the only SASUKE competitor to achieve kanzenseiha twice.
