Miyazawa Koichi (played by Yakusho Koji) is the fourth-generation president of "Kokoshiya", a century-old manufacturer of tabi (split-toe socks worn with wooden clogs) in Gyoda City, Saitama Prefecture. He works diligently every day, but because tabi are fine handmade products, he has to worry about cash flow. At this time, through communication with the head of the bank, Miyazawa began to consider expanding into new areas. Because if he does not start a new business, let alone expand the company's scale, even the survival of the company will face difficulties. The new project he is preparing to start is to use the tabi manufacturing technology to develop a new type of running shoes with a "barefoot feeling". However, for a small local company with only two dozen employees, this is undoubtedly a difficult road. The development of new products lacks funds, talents and R&D capabilities, and will face competition from world-famous sports brands. Although Miyazawa has experienced setbacks, he has overcome difficulties one by one with the help of his family, employees, customers, bank heads and friends. So, can the development of running shoes succeed? What will be the future of "Kokoshiya"?
