The eldest daughter of the Kohashis, Tsuneko was 11 years old when her father Takezo (Nishijima Hidetoshi) died of tuberculosis. Taking her father’s teachings about the importance of ordinary life to heart, she became ‘Toto One-chan’, a paternal figure to her mother Kimiko (Kimura Tae) and two younger sisters Mariko (Sagara Itsuki) and Yoshiko (Sugisaki Hana). She struggles to sustain the family as the head of the household. Right after the war, she launches a lifestyle magazine created for the sake of females together with Mariko and Yoshiko in a devastated Tokyo. It is called ‘Your Life’ and was full of practical articles for readers. With the help of the genius editor Hanayama Isaji (Karasawa Toshiaki), the magazine grew to become essential to females living in the period of high economic growth.
