Tokiko Iwatani (岩谷時子, Iwatani Tokiko, March 28, 1916 – October 25, 2013) was a Japanese lyricist, poet, and translator.
Born Tokiko Iwatani (岩谷トキ子, Iwatani Tokiko) in Seoul, Korea, she moved with her family to Japan at the age of 5, where they settled in Nishinomiya, Hyogo Prefecture. After attending schools in her hometown she entered the English Literature Department of Kobe College, and graduated in 1939. She then joined the publishing department of the Takarazuka Revue, where she became acquainted with the future star Fubuki Koshiji. When Koshiji decided to leave the revue in 1951 to join Tōei and become an actress and singer, Iwatani also quit the company, and moved to Tokyo with Koshiji, whose manager she was for about 30 years, until Koshiji died in 1980.[1]
