Shockingly many children in Japan come from homes that are below the relative poverty threshold as Japan has one of the highest rates of child poverty in the developed world. According to the Ministry of Health, Labor and Welfare, one out of six children lives in poverty. Reflecting this reality some citizens are taking action; one successful solution are 'kids' diners' or cafeterias for the underprivileged. Typically at these 'diners' volunteer staff cook donated foods. Hot meals are provided free or very cheap to children from homes unable to provide healthy meals. Volunteering at these local 'diners' is an example of a fast-growing activism. The film depicts modern Japan seen through the eyes of children whose lives revolve around 'The Kids' Diner.' The film explores themes of community solidarity as no one can live alone.
