The Ninja Medals (忍者メダルNinja Medaru) are the Symbols of the Ninja Guardians for each Tribe. When the main Ninja Medals are inserted into the Ninpou Cellular the main 5 Shinobiman can transform into their ranger forms. When Shinobi Black inserts his Five into his Katana Changer, he can transform into his Ranger form. The Ninja Medals are also used to control the Ninjuu Machines by having the Shinobimen insert their changer into a special slot inside the cockpit. In order for the Main five Shinobimen to transform into their Super Modes they need to insert the Sacred Ninja coins into the Ninpou Cellular and pronounce “Ninpou: Super Ninjuu Transformation (忍法：超ニンジュ変身Ninpō: Chō Ninju Henshin)”
