Nakamura is the custodian of Seaford High School as seen in Fat Chance. He saved Milton from falling off a ledge and Milton sees him as his guardian angel. He used to be a sumo-wrestling champion and even has a victory dance called The Nakamura Stomp. He retired from sumo-wrestling when a rookie named Yamazaki beat him in a sumo match, but with the help of Milton and the Wasabi Warriors he was able to get back into sumo-wrestling, go to Japan and retire from his custodian job. It is also mentioned he went to a game show called Are You Willing to Lose Your Life Savings and lost all of his life savings because of that, even worsening his failed sumo career. His name was inspired by 'The Nakamura store' from 'Hannah Montana', a previous show Jason Earles worked on.
