Aoba Johsai's volleyball uniform

The boys' volleyball club's uniform consists of a white tracksuit with turquoise details. The members wear turquoise t-shirts and white shorts during practice matches, and often don a lime green sports bib on top. During official matches, all the players excluding the libero don a white jersey with turquoise details, and turquoise shorts with a white vertical stripe on the side. The libero has a contrasting jersey in turquoise with white details. If they have to play against a team with a similar looking uniform, they have an alternate outfit - a turquoise jersey with white details, and the libero, a white jersey with turquoise details.

Volleyball Club

The official banner for Aoba Johsai reads "Rule the court" (コートを制す).

The Boy's Volleyball Team is ranked in the top four of the prefecture. For years, it had always been in the finals of the Interhigh and Spring High, only losing to Shiratorizawa. Most of the players are powerful enough to become aces of the team. Most also went to Kitagawa Daiichi Junior High and were invited to Aoba Johsai to join the volleyball team.

Aoba Johsai's most notable players are Oikawa, Miyagi Prefecture's best all-around player, team captain, and setter, and Iwaizumi, the team's vice-captain and ace with his powerful spikes and serves, and also Kyōtani, a second-year that struggles to play along with his teammates but has powerful spikes.

It has been noted that the team's current strength is partly due to the star setter, Tōru Oikawa, who balances and brings out all of the players' abilities.
