Career

Early career Chishiki was born in the Osaka Prefecture, in Japan. He won every race of the calendar except the final round, where he finished second. Chishiki later relocated to the Saitama Prefecture in order to make the jump to minibikes in 2022.

FIM MiniGP (2022–2024) Chishiki joined the newly established FIM MiniGP Japan in 2022. He clinched his maiden podium in his fourth race in the class, after finishing in second place at Motegi. After a consistent end of the season he was placed sixth overall in his rookie year. That same year he competed in the NSF100 HRC Trophy where he finished as runner-up.

In 2023, Chishiki entered his second MiniGP season. He scored a second place in the opening race at Okegawa, which would be his only podium in the whole season, and finished in fourth place overall. In 2024, Chishiki faced his third and final year in the MiniGP ladder. He started the season with five consecutive wins at Tsukuba and Okegawa, and went on to clinch the series title at the final round. This result meant he would get the chance to compete in the FIM MiniGP World Series at MotorLand Aragón—representing Japan alongside runner-up Waku Kunitate in the 160cc class. Chishiki finished third in the opening race, followed by a fifth place in Race 2 and an eighth place in the final race. He finished sixth in the championship standings.

All Japan Road Race Championship (2025–) J-GP3 (2025) Chishiki entered the 2025 All Japan Road Race Championship with the Tetsuta Nagashima-backed MotoUP Jr Team in the J-GP3 class—with Waku Kunitate as teammate. Aboard a Honda NSF250R, Chishiki had a strong debut season in the All Japan, scoring a seventh place in the opening round at Sugo. In the penultimate round at Okayama, he qualified in the front row after setting the third best lap time, and finished the race in fourth place after a last lap battle with Shizuka Okazaki and Kotaro Togashi. At the end of the season he was the highest placed Special Participation rider which earned him a direct spot in the 2026 Moto4 Asia Cup.

ST600 (2026) During the Autopolis round of the 2026 All Japan Road Race Championship, Chishiki made his ST600 debut with TN45 Mirai Racing, aboard a Honda CBR600RR, replacing the injured Tetsuya Fujita. He qualified ninth but crashed in the race when he was running in eighth place.

Moto4 Asia Cup (2026) On his debut weekend in the Moto4 Asia Cup at Buriram, Chishiki won both races by pulling away from the leading group halfway through the race.
