We visit an editor at a long-standing magazine publisher in Tokyo, Japan. Her job is to actually test out the recipes as explained by chefs before they are published. She follows recipes word for word to evaluate how they should be adjusted for the average reader at home. In a different segment, we meet the president of an established manufacturer of ramen noodles. His style of quality control is to visit the shops that use his noodles and taste what's going on.

A famous festival of snow sculptures is held annually in Hokkaido Prefecture, northern Japan. We visit the site of a giant snow sculpture being created and talk to the team's supervisor, Mr. Morioka. As he knows just how cold it can be to work outside in Hokkaido during winter, he has a pub owner cook warm lunch for his team.

We also visit a family-run Somen noodles plant. Winter is the best time to make Somen, so it's very cold inside the factory. But the family has a frugal lunch to warm their bodies up.
