An Yong Hak is one of roughly 300,000 ethnic Koreans living in Japan. He attended a pro-Pyongyang school in Japan and played 40 times in midfield for North Korea, facing Cristiano Ronaldo, Kaka and Yaya Toure at the 2010 World Cup. An says attendance at Korean schools in Japan is falling and North Korea’s squad is likely to contain only one Japanese-born player.
