Keisei Tominaga (pronounced Kay-say Toe-may-nawga) emerged as one of the top scoring guards in the Big Ten Conference as a junior. The 6-foot-2 guard garnered honorable-mention All-Big Ten honors, as he averaged 13.1 points per game in 32 games, including 14 starts. He shot 50 percent from the field, including 40 percent from 3-point range, while hitting a team-high 66 3-pointers to rank eighth in the Big Ten in 3-pointers per game. He also led NU from the foul line, going 46-of-53 from the line, including his first 23 free throws of the year. Tominaga was one of six players in Division I to shoot 50 percent from the field, 40 percent from 3-point range and 85 percent from the line while averaging double figures in 2022-23.
He totaled a team-high 22 double-figure efforts, including 13 of 14 games after moving into the starting lineup on Jan. 18. In that span, he averaged 17.4 points per game on 53 percent shooting. He had eight of his team-high nine 20-point games in that span, including a career-high 30-point effort against Penn State on Feb. 5. Tominaga was at his best late in the season, as he helped NU to a 6-3 finish by averaging 20.3 ppg. Among Big Ten players, his average of 20.3 ppg from Feb. 1 to the end of the season trailed only National Player of the Year Zach Edey (Purdue) and first-team All-American Trayce Jackson-Davis (Indiana).
He closed the year with a 23-point effort against Minnesota in the Big Ten Tournament, hitting 8-of-14 shots from the field and going a perfect 5-of-5 from the line. Tominaga had eight 20-point games following his move into the starting lineup. His role continued to expand following the season-ending injuries to Emmanuel Bandoumel and Juwan Gary. The surge began on Jan. 25 when he had 22 points in a then-high 33 points in a loss to Northwestern. He erupted for a career-high 30 points against NCAA qualifier Penn State on Feb. 5, going 12-of-18 from the field, including five 3-pointers. That began a stretch of five straight 20-point efforts, the longest string by a Husker since former NBA performer Tyronn Lue in 1998. He followed up with 24 points at Michigan before keying a remarkable comeback in the win over Wisconsin on Feb. 11. In that game, he had 12 points in a 20-2 run that erased the Badgers’ 17-point lead. In all, he finished with 22 points, including five 3-pointers. He keyed NU’s win at Rutgers with 22 points, as Nebraska scored 82 points on the Big Ten’s top defense before closing the run with 20 points and a season-high four rebounds in NU’s overtime win over Maryland on Feb. 19. He also added 20 points on 7-of-11 shooting in NU’s loss to Michigan State on Feb. 27.
