The Tanaka Boys is a band in Kuu Kuu Harajuku.
HJ5 first met the Tanaka Boys at the Kawaiification Festival in The Kawaiifier. They were scheduled to take part in a "battle of the bands" competition, which ended up being nothing more than a glorified chess game. Like HJ5, the Tanaka Boys thought the entire idea was stupid.
The Tanaka Boys had a minor appearance in Delectabubbles where they were supposed to be participating in the Yum Yum Delectabubble Band Competition. They looked like they were trying to warn HJ5 about something, but the bubbles were soundproof, and Madame Shhh.
