Japanese actor, dancer and singer. He is best known for his role as Shusuke Fuji in The Prince of Tennis musical series, Tenimyu, and the live film adaptation. Aiba was a former member of the disbanded three-men streetdancing group called Brights. The other two members included Atsushi Koga and Takuya, who would also happened to later play Akutagawa Jirou in Tenimyu with Aiba. The group had to break up because Aiba had to join Avex (his previous agency) after he won in the Junon Boy contest. There were originally 4 people in the group, but one dropped out, so that left Aiba, Takuya, and Atsushi, in Brights. At that time, Aiba was still an amateur at dancing and he's stated in past blog entries that he owes a lot to Takuya, who was already an experienced dancer by then, for teaching him various things.

He is now member of "top coat" agency.
