The Yamato Transport Company, Ltd. (ヤマト運輸株式会社, Yamato Un'yu kabushiki gaisha, YTC) is one of Japan's largest door-to-door delivery service companies, with a market share of 41%, competing closely with Sagawa Express and Nippon Express. Their head office is in Ginza, Tokyo. The company's trademarked term for their express door-to-door delivery service, TA-Q-BIN (宅急便, takkyūbin) was used, with permission, in the original Japanese title of Kiki's Delivery Service (魔女の宅急便, Majo no Takkyūbin, lit. 'Witch's Express Home Delivery') (in which Yamato is a co-producer) instead of the generic term takuhaibin (宅配便). Takkyūbin is sometimes used in Japan as a generic term for all express home delivery services, but the company defends the trademark to avoid it becoming genericized.
