Takei began playing badminton at age five at the Ome Junior club in Tokyo. As a fourth-grader, he won a national elementary school championship, leading to his selection for the U-13 National Development squad. He later attended Inawashiro Junior High School and the Futaba Mirai Gakuen High School.
Takei made his international debut in 2015 at the Singapore Youth International Series. He won his first junior international title in 2017 with a victory in the boys' singles at the U-15 Asian Junior Championships. That same year, he won a gold medal in boys' doubles at the Singapore Youth International with partner Shohei Noguchi. In 2018, he earned a silver medal in boys' singles at the Jakarta Open Junior International. The following year, he was part of the Japanese team that won a bronze medal in the mixed team event at the 2019 World Junior Championships in Kazan. His junior career also included numerous domestic titles, including victories at the All Japan Junior High School Championships, the National High School Championships (Inter-High), and the All Japan Junior Championships.
Career
After graduating from high school, Takei joined the NTT East Badminton Team on 1 April 2022. In 2023, he won his first senior international title at the Thailand International by defeating Heo Kwang-hee of South Korea in the final. Later that year, he finished runner-up at the Bahrain International, losing to compatriot Minoru Koga.
In 2024, Takei reached the final of the All Japan Championships, finishing as the runner-up to Yushi Tanaka. His run to the final included wins over Kenta Nishimoto and Riku Hatano, and he advanced from the semifinals after Koki Watanabe withdrew due to injury. Takei attributed his performance to six months of training under former national player Kento Momota.
In May 2026, Takei reached his first BWF World Tour final at the Super 100 Baoji China Masters, finishing runner-up to China's Sun Chao. In July, he advanced to his second World Tour final, and his first at the Super 300 level, at the Canada Open. En route, he defeated compatriot Minoru Koga in the second round and Olympic bronze medalist Lee Zii Jia in the semifinals, ultimately finishing as the runner-up after falling to Yudai Okimoto in an all-Japanese final.
