Mikan no taikyoku

Ten years before the outbreak of the Second World War in Asia, a Japanese Go master and his Chinese rival meet in China to play a game of Go (loosely described as an Asian version of chess). It soon becomes evident that the Chinese master's son is the most talented player that the Japanese master has ever encountered, and he convinces the boy's father to let him bring the child back to Japan to train him as a professional Go player...
