Little was expected of Otsu when he made his debut in the Japanese single-seater series last year for Team Mugen, but that all changed when he won a race, earned Rookie of the Year honours and replaced Drago Corse-bound Nirei Fukuzumi at the title-winning Dandelion team for 2022.
Having been second-quickest in post-season testing at Suzuka last year, Otsu would go on to outpace his new teammate Tadasuke Makino in both pre-season tests, raising hopes that he could be something of a dark horse for title honours.
