Gatō is a minor villain in Naruto who also acts as one of the two main antagonists in the Land of Waves Arc. He was a corrupt businessman and a drug dealer in the Land of Waves.
Finding the Gatō Company years ago, Gatō took control of the Land of Waves' shipping routes and created a monopoly by isolating the country from the outside world, making it impoverished and hunger-stricken. He also dealt with a resident named Kaiza with a public execution in order to demoralize the people so they would not stand up to him. However, with news of a bridge to the mainland being built, Gatō hired Zabuza Momochi to assassinate the bridge maker Tazuna and discourage the bridge's construction. But due to Team 7's intervention as Tazuna's bodyguards, and Zabuza's arrogance, Gatō decides to take matters into his own hands. Making his move once Zabuza's arms were broken during his rematch with Kakashi, Gatō arrives with his men to finish the job himself while also killing Zabuza so he would not have to pay him for his services. But Gatō's scheme backfired when Zabuza, near death, used the last of strength to brave through Gatō's men to kill him.
