"Noriko Sato soared through the middle of the action to seize the Snitch"
-- match report Japan v Nigeria, Daily Prophet, 10 June 2014 (Pm)
Japan won their matches against Poland (350-140) and Nigeria (270-100). During the semi-final match against Bulgaria, Sato rescued Bulgarian Beater Boris Vulchanov who had been knocked out by a Bludger. While helping him, she was unable to keep looking for the Snitch, so Seeker Viktor Krum also refrained from doing so, sportsmanship that was applauded by the crowd. In the end, Japan lost to Bulgaria by 610 points to 460 (Pm).
