A red hat and red t-shirt. Characters on the back say he's an "Onion Master." Tsuyoshi Shimizu, the Onion Master, is 38 years old. His incredible Welsh onions— “sweeter, thicker, and softer than fruit” —have reached sugar levels of up to 22.5 degrees. As determined as Tsuyoshi Shimizu is to create his own ultimate Welsh onion, the declining number of farmers in Japan has not escaped his attention. He believes that the best way to solve this problem is to get more people aware of agriculture. Fortunately, Tsuyoshi Shimizu happened upon the chance to teach sixth graders of Terazu Elementary in Yamagata Prefecture’s Tendo City about agriculture. He suggested that they go beyond the simple farming curriculum in public education, which cannot foster true understanding or enjoyment of agriculture, and organize an extracurricular farming club, in which children would get the real farming experience. And so, in the spring of 2019, he served as the guide to 19 sixth-grade members of a Farming Club, bringing real farming experience to kids. Kids would undertake everything from the sprouting, planting, cultivation, harvest, and even sales of produce. Through this new undertaking, they gained independence and new outlooks on agriculture. See the efforts of a Welsh onion farmer looking to change all Japan’s agriculture, and what 19 hard-working sixth-graders manage to produce in this total coverage documentary.
