Mori Tetsuya, a third-generation fisher in Akkeshi town, northern Japan, supports his family with income from catching sea urchin and other marine products. In 2021, a red tide hit the town for the first time, killing 80% of the sea urchins in the area. Over 60 years, local fishers have established a unique farming method for these creatures. To protect them from the fast current and cold seawater, young urchins are released on the seabed by a specially trained diver in a suit weighing 60kg. Tetsuya is responsible for this dangerous mission. The program follows him for 2 months as he struggles in the face of the unprecedented damage.

Kids in Osaka Prefecture rarely call Tanahara Yasuko by her real name. Instead, they affectionately refer to her as simply, Auntie. For decades, this 82-year-old baseball coach has used tough love to get the best out of her young players both on and off the field. She's a local legend, and her 140-member team is a powerhouse in Japan's Little Leagues. Auntie is a moral compass for the children she mentors – especially those who must navigate sport and school while growing up in single-parent households.
