Takashi was a 24th century sumo wrestler.
Kathryn Janeway once watched Takashi compete during the 77th Emperor's Cup, where she recalled that Takashi forced his opponent, Kar-pek, out of the circle in less than three seconds. Chakotay and Tuvok disagreed, stating that Takashi had actually lost the match because his knee broke the sand. (VOY: "Latent Image")
