Kei Koizumi (小泉 慶, Koizumi Kei, born 19 April 1995) is a Japanese footballer who plays as a defensive midfielder or right back for J1 League club FC Tokyo.
[1] Koizumi started his career as a junior player with Yokohama F. Marinos, but the club did not promote him to their Under-18 team.
He subsequently became a regular in the school team that won the Prince Takamado Cup in 2013.
His ability to play in a number of positions across defence and midfield made him an attractive proposition and boss Masaaki Yanagishita was delighted to be able to prise him away from The Big Swan Stadium.
