 The word "takkyūbin" (宅急便, literally home-fast-mail) in the Japanese title is a trademark of Yamato Transport, though it is used today as a synonym for "takuhaibin" (宅配便, literally home-delivery-mail).The company not only approved the use of the trademark — though its permission was not required under Japanese trademark laws — but also enthusiastically sponsored the anime film version of the book, as the company uses a stylized depiction of a black cat carrying her kitten as its corporate logo.Non-Japanese versions of "Majo no Takkyūbin" were not published until 2003 when the book became available in English, Italian, Korean and Chinese.
