Seki was the fastest player ever to take a major title, taking four years and eight months from professional qualification. He took the record from Shibano Toramaru, who took five years and a month.

According to John Power, while analyzing a game of Seki’s a year <before his Tengen victory>, Cho Chikun commented that he was convinced he would soon win a title. Instead of just playing the move everyone would play, Seki looked “for something better and this is the difference between title-winners and ordinary players.”
