UCC stands for Ueshima Coffee Company, a manufacturer of coffee and tea products in in Kobe, Hyōgo. The company started as a store under the name of "Ueshima Tadao Shoten" in 1933. It became limited partnership in 1940 and on 1951, became "Ueshima Coffee Co., Ltd.". The company introduced the world's first canned coffee, "UCC Coffee with Milk" on April 1969 starting the trend for Japanese canned coffee.
UCC Coffee became famous with Otaku ( anime fans) around the world after their canned coffee was featured in the 1997 feature film The End of Evangelion. As a tie-in with the makers of the film, UCC created six coffee can designs featuring the Evangelion characters holding the company's products. These cans subsequently became prized collector's items. UCC continued this partnership when, a decade later, a new set of four Evangelion films began their release with 2007's Evangelion: 1.0 You Are (Not) Alone. The cans were again featured in the film, and UCC again featured illustrations of the film's characters on a limited release of their cans. (Source: Wikipedia)
