In the first episode, Yumi meets the women who are re-defining their roles in Japan's patriarchal society, and the men forced to re-orientate themselves in this new social order.
In episode two, Yumi dives into the country's extreme work culture, visiting obsessive farmers, overworked salarymen and the therapists trying to keep them sane.
Yumi visits hip hop dancing grannies and other members of the nation's sunset generation to find out how this fast-ageing country is coping with unprecedented demographic change.
In the final episode, Yumi hangs out with bartending Buddhist monks, psychedelic pop artists, and shunned biracial communities to explore a national identity in flux and to decipher what it means to be Japanese today.
