Hikaru no Go was published serially in Weekly Shonen Jump at the same period as Naruto. The anime adaptation, as well as Naruto's, were both produced 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.
