is a Japanese professional footballer who plays as a left back for club Machida Zelvia.[3]
Hayashi was born in Ureshino, Saga and started playing football in the third grade of elementary school. He studied at Saga Prefectural Konan Junior High School and later Saga Prefectural Sagakita High School.[4]
Hayashi started his youth football career with Sagan Tosu U-15s and quickly made his way up to the U-18s, being named as a substitute for them in 2016 at just 15.[5] He made his debut for the U-18s in 2017 and became a regular starter in the 2018 season, captaining Sagan Tosu U-18s and helping them finish top of Prince Takamado JFA U-18 Prince League Kyushu and reach the quarter-finals of the Japan Club Youth Cup.[6]
In February 2019, Meiji University announced that Hayashi would be joining their team.[7] He became a registered member of the team in 2021.[8] He made his debut for Meiji University in April 2021, coming off the bench to replace Ren Kato in a 2–1 JUFA Kanto League 1 match against the University of Tsukuba.[9] He made 15 appearances in his first season, scoring two goals.[10] In his final year, Hayashi was named captain and helped Meiji University win the league, despite fracturing his metatarsal midway through the season.[11] [12]
Hayashi was offered a professional contract with Yokohama FC after playing a training game against them for Meiji University – a match he was not originally scheduled to take part in but played due to a clash with exams.[13] It was officially announced in July 2022.[14] He made his debut for the club in March 2023 in a 3–1 league defeat to Kashima Antlers.[15] He also scored his first professional goal in his debut season, scoring in a 1–1 league draw with Sanfrecce Hiroshima.[16] He made 32 appearances and scored two goals across all competitions in his debut season, but was unable to prevent Yokohama FC from being relegated to the J2 League.
In January 2024, it was announced that Hayashi would be transferring to newly promoted J1 League club Machida Zelvia ahead of the 2024 season.[17]
