Hikaru no Go is a manga series, a coming of age story based on the board game Go written by Yumi Hotta and illustrated by Takeshi Obata with an anime adaptation. The production of the series' Go games was supervised by Go professional Yukari Umezawa (5-dan). The manga is largely responsible for popularizing Go amongst the youth of Japan since its debut, and in other areas such as China, South Korea, and Taiwan. More recently it has gained much popularity in the United States. The title is sometimes abbreviated as 'HnG'.
