[2] Miyake won the second race of the season at Okayama, and went on to finish as runner-up in the championship behind fellow Honda junior Ren Sato.

Miyake stepped up to the GT300 class of Super GT in 2020, driving for series newcomers Max Racing in their Lexus RC F GT3.

Miyake won his first Super GT race at Suzuka Circuit in August, and, alongside co-driver Yuui Tsutsumi, finished fifth in the GT300 drivers' championship.

Miyake's 2023 campaign began strongly with a podium at the opening round at Okayama, but his season ended early when his team, Max Racing, was forced to withdraw from Super GT and cease operations after their Toyota GR Supra GT was destroyed in a vehicle fire at the fourth round at Fuji.

In January 2024, Miyake was announced to be returning to Super Formula for the 2024 season, taking the place of Toyota-bound Nirei Fukuzumi at ThreeBond Racing.
