In October 2019, JA Suigo Tsukuba’s hydroponics mitsuba producers confirmed the prefectural GAP (gap, agricultural production process control), which was institutionalized to use prefectural ingredients for the 2020 Tokyo Olympics and Paralympics. On the 16th, we received the confirmation certificate. It was the 12th case in the prefecture and the second case in the same JA after the GAP Promotion Group of the Kasumigaura Branch of the Lotus Root Section of Lotus Root Producers. The Ibaraki Prefecture version of GAP was issued by the JA Suigo Tsukuba Facility Horticulture Hydroponic Mitsuba Committee. All three representatives of the three corporations that make up the organization visited the Prefectural Tsuchiura Joint Government Office in Manabe, Tsuchiura City, and received a certificate from the then director of the Southern Prefectural Agriculture and Forestry Office. Members of the same group have been cultivating hydroponic mitsuba for about 40 years in Imaizumi, Tsuchiura City. Currently, it produces 400 tons of mitsuba per year on an area of about 2 hectares, or about 400,000 cases, and ships it nationwide under the brand name of “Amanogawa cow parsley.” We are proud of our ability to produce high-quality, consistent agricultural products through hydroponics, where seeds are germinated, grown, sorted, packed, and shipped.
Japanese honeywort is native to Southeast Asia and the temperate zone of North America, and in the Japanese archipelago, it grows naturally in Okinawa from the southern Kuril Islands. I have also heard that it grows naturally in China, Korea and Taiwan. The record of cultivation in Japan dates back to the Edo period. Beginning with , the five grains, mountain vegetables, three grasses and four trees, the sowing period, cultivation methods, etc.)” describes cultivation methods and simple ways to eat. Full-scale cultivation began in the Kyoho era (1716-1735) in what is now Mizumoto-cho, Katsushika Ward, Tokyo. The mitsuba cultivation that started in Shimo-Chiba town became the origin of ito mitsuba (blue mitsuba), and later the production areas moved to Chiba, Kanagawa, and Saitama prefectures, and it seems that it spread to Kansai after 1897. Hydroponic cultivation, which is a cultivation method that uses a solution of fertilizer dissolved in water (a culture solution) to grow crops in a large-scale greenhouse, without using soil, was established in Hamamatsu City, Shizuoka Prefecture in the mid-1965s. It seems that what was done was the first step.
Eating habits are supported by many people, such as the life of food and the people who make the ingredients and dishes. The “Nogyo Zensho” was published by Ekiken Kaibara and his older brother, and although he got a lot of his knowledge from Ming’s Agricultural Administration Zensho, it seems to have been written to suit Japanese circumstances. Plants are illustrated, and almost all the plants that were cultivated at that time, such as five grains, greens, and sweet trees, are covered. However, since he traveled around western Japan, including the Chikuzen domain, and wrote based on that, the proper growing season seems to be suitable for western Japan. In addition, as a part of agricultural policy, the foresight that concretely discusses the idea of national interest, such as encouraging farmers to cultivate medicinal seeds, is also highly evaluated. It has been evaluated as the most systematic book on agriculture, and its impact on Japanese agriculture is immeasurable.
