Jump to:


Kiyoko Takagi was born in Niihama, Ehime Prefecture, Japan, on 15 March 1908. She lost her mother when she was 5 years old. At the age of 11, she moved to Kitakyushu City, where her relatives lived. In 1922, after she graduated from school, she joined the Kokura station of the Japanese National Railways as a telephone operator, and she worked for the
Japanese National Railways until 1964.

In 1941, when she was 33, her husband, an army captain, died in a fierce battle on the Malay Peninsula. She then raised her three sons as a single mother, with
some help; including leaving the three children with her relatives for several years. Upon retiring from the National Railways, she spent her time teaching flower arrangement – something she started doing in her 30s. She supported a company (where her second son served as chairman) that specialized in water supply products and water filters.

Kiyoko Takagi passed away in Kitakyushu City, Fukuoka Prefecture, Japan, on 7 August 2019, at the age of 111.
