Licca-Chan (spelt Rika-Chan リカちゃん) is the Japanese equivalent to Barbie.
Kids often start with Popo-chan – a more toddler like doll.
Then, as they get older they’ll often be given a Licca-chan doll.
Chan is a honorific used at the end of a name to show affection or familiarity, especially for girls.
First released in 1967, Licca-chan is a classic and nostaglic doll for women in Japan.
In 2001, to conincide with the royal baby (Princess Aiko) in the Imperial family, they released a pregnant Licca-chan.
You could send away the postcard to receive the baby doll.
