Licca-chan

Licca-chan (リカちゃん, Rika-chan), full name Licca Kayama (香山リカ, Kayama Rika), is a Japanese dress-up doll series introduced in Japan on July 4, 1967 by Takara created by former shōjo manga artist, Miyako Maki, who is also the wife of Leiji Matsumoto. Parodying the same popularity as the Barbie series in the United States, Takara had sold over 48 million Licca-chan dolls as of 2002, and over 53 million as of 2007.

A spin-off anime series titled Super Doll★Licca-chan (スーパードール★リカちゃん, Sūpā Dōru Rika-chan) aired on TV Tokyo in 1998 to 1999, and later across other Asian channels. Kodansha also serialized a manga based on the anime in its monthly manga magazine Nakayoshi. Though the intention of the series' production was to expand the regular dress-up doll series in a line of action figures, the new figures were only a mild success and did not remain in production for long.
