The oldest manga in japan

When I was an university student,  one chinese student studied abroad in my university. He like to read manga and watch anime. One day, he asked me why there are many anime and manga in Japan. And he also asked me which manga is the oldest manga.

 So, today I write about the oldest manga in Japan. In our opinion, Choujyu zinbutsu giga is the oldest manga in Japan. The manga was drawn about 800years ago. The character is rabbits, turtles , monkeys and etc. they were personified.

 If you go to Kyoto musium or koudaizi temple, you can see this choujyu  zinbutsu giga. this is one of the history of Japanese manga.
