Anime is by far the most popular piece of Japanese popular culture to leave Japan and spread to other parts of the world. But as the vast majority of anime series are adaptations, that leads to the question: From what are these anime adapted?
Of course, most are originally manga series that become popular in serialized manga magazines—e.g. Naruto, Bleach, Dragon Ball, and Full Metal Alchemist. A much smaller number come from visual novel games—e.g. Fate/stay Night, Steins;Gate, and Clannad. But oft overlooked is the third place anime adaptations come from: light novels.
