Tap Kids was a Johnny's Entertainment unit considered a spin off of J.J. Express and often perform in tandem with or to introduce J.J. Express. It is uncertain at this point whether they are still considered a part of the bigger group, as they are always photographed separately and have stopped appearing in J.J. Express photoshoots. Their specialty is tap dancing, though the distinctive tapping sound is prerecorded.
