The Hercules Factory is the training academy for Justice Chojin.
It is first shown at the beginning of the second series although many justice chojin from the first ostensibly trained there. It is reopened when the first series' heroes are defeated by the members of d.M.p to train a force of young and vital justice chojin in their place. The training is gruelling, and to graduate each fighter must win a match against a member of the older generation of justice chojin.
