■ Miura Farm, cultivating Senshu Yellow Onions, the ancestor of onions distributed in Japan
Senshu Yellow Onion is said to be the first yellow onion cultivated in Japan during the Meiji era, and the parent of many onions distributed in Japan. Therefore, it is recognized as a "Naniwa traditional vegetable," a unique variety cultivated in Osaka for over 100 years. Farmers cultivating Senshu Yellow Onions have decreased because it does not keep well, is susceptible to pests, and its irregular shape makes selection difficult, resulting in many non-standard products. Amidst this, Miura Farm, which has been cultivating Senshu Yellow Onions since 2016, is committed to protecting this valuable Senshu Yellow Onion and carries out all tasks from seeding, planting, harvesting, and selection by traditional manual methods.
