Hikaru no Go was published serially in "Weekly Shonen Jump" for "NARUTO" and the same period. And the animated cartoon was produced as well as "NARUTO" by "Studio Pierrot". When the comic was serialized, "the game of Go" became a boom among children in Japan.
This movie is highly recommended for those who know the Go game, because it does play around with AI, making it do the most absurd moves possible, which still serves the main goal - speed.
