Aizu started playing football in his first year at Chitose Elementary School with Seijo Champ SC and after MIP FC, he joined Kashiwa Reysol's academy from the end of the fifth grade of elementary school until he graduated from high school. In May 2014, when he was a member of the Kashiwa U-18 team, he was registered in the first team as a second-class player. He was not promoted to the first team after graduating from high school and went to the University of Tsukuba, where he was a regular in his first year, and in his second year, due to team conditions, he switched from side-half to side-back.

He joined FC Gifu in 2019.
