Onagawa town in northeast Japan was devastated by the 2011 tsunami. The town's only supermarket, which goes back 100 years, has now reopened after a 9-year closure. The relaunch was led by Sato Hiroki, the fifth-generation owner of the family-run store. As he tried to keep alive the wishes of his mother, older sister and grandparents, who died in the tsunami, he was also raising an adolescent nephew, his late sister's only son. The program follows the relationship of the uncle and nephew over the 9 years following the tsunami.
