We visit a prison in Shiga Prefecture, western Japan, where about 500 inmates engage in prison work programs every day. We take a look at the bento lunches of the correction officers who keep watch over the inmates 24-7. In another story, we cover a man who works for a company that manufacturers emergency rations. To know more about his trade, he eats only emergency rations for lunch every day, and the insight he's gained from that lunch style has turned him into a trusted voice in the industry.

We visit the canteen of a taxi company in Tokyo to meet Hiroko Kawano. She's 77 years old but younger than ever, continuing her 34-year stint as the chef there. She acts as a mother figure for the taxi drivers, praying for their safety and cooking meals for 50 people. We then visit Niigata Prefecture, the largest producer of knitwear in Japan. Take a peek into the secret techniques behind the clothing made here, and relish the tasty lunches that people bring to the factory.
