In terms of popularity the character has been compared to Walt Disney's Mickey Mouse,[10][11][12] and the character is considered to be an iconic figure in Japan.[13] The character has received criticism in Chinese media outlets where they considered Doraemon to be a politically subversive character and that it was a tool of Japan's “cultural invasion".[14][15] In his book Japan Pop: Inside the World of Japanese Popular Culture, author Timothy J. Craig wrote that the character of Doraemon "Though Doraemon is himself a high-tech product, he possesses an endearing personality that captivates young audiences. He is both a full member of Nobita's family and an intimate friend to Nobita and his companions. Portrayed in this way, Doraemon represents the optimistic view of the relationship between technology and humanity."[16]
