Niji no Nana-chan means Nana-chan of the rainbow. She was made by Shiba in 1971 and is 26cm tall. She was supposed to be a rainbow fairy that prayed to god to be allowed to get close to humans, so she was transformed into a doll.

Her line included 7 wigs (Nana by the way means seven in japanese) most of which were fantasy coloured, which was rather original at the time.

There was also a tanned version made which is rare and expensive.

Family members included her mom and dad, as well as a friend named Mirei and a boyfriend, Kenji.
