A unified Korean hockey team lost a grudge match 4-1 to Japan for their third straight Olympics defeat in front of a partisan crowd that included the North Korean cheerleaders and a Kim Jong Un lookalike. The home fans chanted "We are one" even as the first joint Korean team faced another heavy defeat. At least they had a goal to cheer -- scored by Randi Griffin, one of three Americans in the squad with Korean parentage. Korea lost 8-0 to both Switzerland and Sweden and the Japan clash had extra spice for Koreans in the North and South who blame Japan for colonising the now-divided peninsula from 1910-1945. "I came to tonight's game because I wanted to support our team when they play against Japan," said Kim Yoon-hye, a 28-year-old teacher from Seoul. Park Geum-taek, 44, from Olympic host city Pyeongchang, added: "Given the history of our countries, I feel like we must win all sporting games against Japan."
