The Tokyo Metropolitan Police Department Commissioner oversees Inspector Koichi Zenigata and wields significant authority within the police force. Following a high-speed highway pursuit involving Lupin III and Suzuki's men that caused substantial property damage and public disruption, the Commissioner suspended Zenigata from duty. He confiscated Zenigata's badge, handcuffs, and service weapon, citing the operational chaos as damaging to the department's reputation. Later, during the climax at Suzuki's corporate building after Lupin III exposed Michael Suzuki's illegal genetic experimentation and cloning, the Commissioner personally led a team of officers to arrest Suzuki. His arrival and action, coordinated with Zenigata and Lupin, resulted in Suzuki's apprehension while allowing Lupin to escape.
