[1] Makino started karting in 2004 at the Kansai Kartland circuit in Sakai and made his race debut the following year.

He would go on to dominate Super FJ and JAF F4 for the next two years, winning all but one race he competed in against the likes of Yūki Nemoto and Shunsuke Kohno.

He had a difficult start to the season, scoring only twice in the first half of the year before breaking his wrist and finger in an accident with Harrison Newey at the Norisring.

[2] He scored points regularly until he surprisingly won the feature race at the Monza in the second half of the season thanks to good strategy.

In the end of 2020, Makino suffered from meningitis and thus skipped the Super Formula finale, where he was replaced by Hiroki Otsu.

The next season he replaced Jenson Button as he competed with Team Kunimitsu alongside former GT500 title winner Naoki Yamamoto.

Makino continued racing with the team for the next couple of seasons, but had to skip one round due to illness in 2021 and was covered by Hideki Mutoh.
