1. Gin Tama: 9.6

Gin Tama is a Japanese anime that aired on the TV Tokyo Corporation since April 4, 2006. Set in an alternate late Edo period, human beings are attacked by aliens called Amanto. Japanese samurais join the battle against the aliens, but when the Shogun realizes the power of aliens, he betrays the samurai and surrenders to the aliens. The Shogun writes an unequal contract with aliens allowing the aliens to enter the country and places a ban on carrying swords in public. The swords of samurai are taken away so they can no longer resist the aliens. After that the Shogunate becomes a puppet government. Against this backdrop, viewers follow Gintoki Sakata, who works as a freelancer alongside his friends Shinpachi Shimura and Kagura in order to pay the monthly rent.

The Gin Tama manga has sold 50 million units in Japan as of May 2016. Also, the animated adaptation of Gin Tama is the highest rated Japanese anime series on Douban Movie for its ironic yet moving plots. Its derivative mobile games have been released only in China due to their enormous popularity.
