The 2016 earthquake damaged Kumamoto Castle, leaving its stone walls crumbling. We meet the stonemasons carefully restoring each stone to its original place and discover what they do for lunch.

This episode features a collection of onigiri rice balls that fuel artisans across Japan. From a roof tile artisan who loves rice cooked in a clay pot to beat the summer heat, to gardeners managing the Japanese garden of a museum—what kind of onigiri keeps them going? We also visit workplaces of other masters of their craft, including ink makers and metalworkers, showcasing their unique and carefully made onigiri.
