The Tachibana Institute is a robotics lab under the direction of Dr. Tachibana in Getter Robo Daikessen !. It served as a business partner to the Saotome Institute, sharing technology such as the Getter Machines.
The Tachibana Institute's main directive is the production of robots for the greater good. While initially built to avoid battle, attacks from various sources forced the Institute to restyle their creations. Entering a partnership with the Saotome Institute and their resources in combat, the Tachibana Institute developed robots for battle including the Getter Robo Go.
