Two women, aspiring documentary filmmakers, find themselves trapped in a monster-plagued Tokyo in 2003.

An eight-year-old boy is willing to do whatever it takes to end World War II so he can bring his father home. The story reveals the indescribable love a father has for his little boy and the love a son has for his father.

'Ikigai' follows Mayumi, a 9-year-old girl, as she tries to find balance in her Japanese identity and American nationality. Hanako, her mother who celebrates their culture through Nihon Buyo, sees Mayumi's new school as an opportunity to share their culture with the white students. When Mayumi is assigned a show-and-tell presentation, she takes it as a chance to prove to her classmates that she is not that different from them. But, that plan is soon ruined when Hanako unexpectedly shows up and teaches the class a Japanese dance, embarrassing and exposing Mayumi's cultural background. After coming home ashamed of her mother and Japanese identity, Mayumi receives guidance from her parents that motivates her to return to school and redo her show and tell in a way that would make her ancestors proud.
