Career Early career

Sakaguchi began his senior competition career in 2015, competing for Sutekina Racing Team in the final four rounds of the F4 Japanese Championship. Through eight races that season, he registered a podium at Motegi and finished outside of the points just once, taking 10th in the championship. The following season, he graduated to the Japanese F3 Championship, taking part thanks to the Honda Formula Dream Project. Sakaguchi continued competing in F4 during 2016, tallying his first win in the series at Motegi en route to a second-place point finish. In his maiden F3 season, Sakaguchi would finish 9th in points.

Sakaguchi returned to F3 in 2017 with Honda support, finishing an improved 6th in points, netting his first podium in the series at the penultimate race at Sugo. In 2018, Sakaguchi joined Toda Racing and built upon his previous results, finishing fourth in points off the back of five podium finishes in 17 races. Following the 2018 season, Sakaguchi was released from his junior driver role at Honda.

Sakaguchi raced in F3 2019 season tallying three podiums in five races driving for TOM'S. Following the Japanese F3 split at the end of 2019, Sakaguchi competed in both of the resulting series during 2020. In the Super Formula Lights series, Sakaguchi ran the full season with B-Max Racing. Despite finishing just one race outside of the podium positions, he would finish second in the standings, nearly 40 points behind Ritomo Miyata. In the K2 Planet-promoted Formula Regional Japanese Championship, however, Sakaguchi won all eleven races that he competed in, taking the championship by just over 50 points despite missing the triple-header at Sugo.

Super Formula Sakaguchi would have been his debut in the Super Formula Championship with Team Mugen, filling in for Nirei Fukuzumi, who was competing in the F2 Championship that weekend. However, the race was canceled due to inclement weather. Later, in 2020, he filled in for Kondo Racing's Kenta Yamashita during the Super Formula Championship round at Okayama. However, Sakaguchi once again was unable to make it to the grid, crashing on the warm-up lap and failing to officially register his Super Formula debut. In his rookie season, Sakaguchi claimed two podium finishes en route to a seventh-place points finish, taking second at the rain-shortened round at Autopolis and the second event at Motegi. Sakaguchi endured a quiet 2023 season in Super Formula, finishing a season-high fifth at Motegi.

Super GT GT300 2019 marked Sakaguchi's first experience with sports car racing, as he joined K-Tunes Racing for the 2019 Super GT Series season, competing alongside veteran Morio Nitta in the GT300 class. The drive came about thanks to Sakaguchi's uncle, Ryōhei Sakaguchi a racing driver who was competing in the series and had connections with the K-Tunes team. For 2021, visa issues for Frenchman Sacha Fenestraz enabled Sakaguchi to add a part-time campaign in the GT500 class of the Super GT series. He would pair with Ryo Hirakawa for the first five rounds of the season, taking pole at the opening round alongside two podium finishes.

Ahead of 2022, Sakaguchi moved to the GT500 class full-time, pairing with Yuji Kunimoto in the #19 TGR Team WedsSport Bandoh entry. Despite Sakaguchi himself claiming three individual poles and the entry scoring four total, the team would only finish 11th in the championship, finishing no higher than fifth in any given race. At the conclusion of the season, sports car racing publication Sportscar365 named Sakaguchi as an honorable mention for their GT500 Driver of the Year. Sakaguchi would return to the team in 2023, paired once again with Kunimoto. The duo would claim the first GT500-class victory for Bandoh since 2016 in a red-flag shortened event at Suzuka, concluding the season 12th in the overall championship.
