Well, since we've been talking so much about the end of the world, I figured I'd talk about how our neighbors to the east have handled the Apocalypse in their respective media. Probably the best example of Japan's attempt to handle the end of the world is the series Ekkusu, which translates simply to X.
X is a manga and Anime series created by Clamp, a creative team made up of four japanese women (a rarity in the manga business). X is Clamp's attempt to push into apocalyptic fiction, something vastly different than their previous titles (they were previously known for creating shoujo manga, which literally translates to manga aimed at young girls). It combines elements from various end of the world scenarios, both secular and religious, with its own mythos.
