享保元文諸国産物帳, Yoshimune ordered all governors to list up their products: crops, flora, fauna, mineral, and animal products. This project had been governed by Shohaku NIWA（1691-1756）who was a scholar of natural products, completed several years after 1735. He is a doctor born in Matsuzaka, Ise Province (now Matsusaka City, Mie Prefecture). He learned a study of medicinal herbs from Jakusui INOU (1655-1715) in Kyoto, and was later appointed as a drug-recipient of the Edo Shogunate. Along with Genjo NORO (1693-1761), Masakatsu UEMURA (1695-1777) and others, he was ordered to manage the Shimousa medicinal-herb garden and cultivate medicinal herbs while conducting drug research in various places. Takidai wild medicine garden in Shimousa (now Yakuendai, Funabashi City, Chiba Prefecture), which was managed by Shohaku, is the origin of the name of the place.

It seems that it is not suitable for food cooked by boiling because the amount of water is small and the spiciness tends to be strong, and the spiciness is decomposed by grate white radish.

【主な特徴】

Shohaku was employed as a shogunate doctor in 1722 with a thirty-man defend (approximately 43.5 bales: approximately 17.4 koku of rice). He was entrusted with the management of a 150,000 unit of land measurement (about 495867.769 m2) of a medicinal garden in Shimousa (Chiba). Also, in 1727, “Fukyurui-Hou” was published to explain treatment methods and medicines for the common people. It was edited by Shohaku and Ryoteki HAYASHI and was published by the Shogunate.). In the Shogunate, he disguised himself as an order from the shogun and requested each clan to investigate and write down all the flora and fauna in Japan. It seems that they gathered from various countries between 1735 and 1736. It seems that each domain took two to three years to respond to the request, asking for sketches and drawings to be attached to the collected product books. Completed in 1739. Unfortunately, the original of this product book seems to have been lost. It seems that there is no official record of the shogunate because the product book is not an official notice of the shogunate. There is no record of whether Yoshimune saw it or not. In mid-March 2022, JA Irumano (Kawagoe City), which operates in 13 cities and towns such as Kawagoe City, Tokorozawa City, and Iruma City in the southwestern part of Saitama Prefecture, is a processing facility specializing in Sayama tea, which is a specialty of Sayama City. The center is open. It seems that the work will be streamlined by integrating the two bases, which will lead to the expansion of production of Sayama green tea, whose production has been decreasing in recent years. Sayama green tea is one of the three major teas in Japan along with Uji tea and Shizuoka tea in Kyoto, but its popularity and production volume are different from those of both production areas. The person in charge at JA Irumano says, “I want to strengthen production and sales capabilities and create a system to support Sayama tea.” It seems that the Sayama Tea Center is a collection of two processing facilities, JA Irumano, located in Tokorozawa City and Sayama City, and has been set up in the area adjacent to the agricultural products direct sales office “Agureshu Genki Village” (Sayama City). In addition to the conventional tea processing equipment, a shower room has been newly established to ensure hygiene management, and equipment for burning tea leaves has also been introduced. It seems that 12 staff members are working. Until now, it had been processing and selling as JA Irumano and processing about 86 tons per year by consignment processing from tea producers, but it says that it can increase the production volume by operating the new facility. JA Irumano Agricultural Cooperative is located in the southwestern part of Saitama prefecture, in the metropolitan area 30 to 60 kilometers from the city center, and has a total land area of 69,843 hectares, which occupies about 18.5% of Saitama prefecture. It is an area. This area consists of 10 cities and 3 towns (Kawagoe City, Tokorozawa City, Iino City, Sayama City, Iruma City, Fujimi City, Sakado City, Tsurugashima City, Hidaka City, Fujimino City, Miyoshi Town, Moroyama Town, Ogose Town, Iruma District.) Consists of. The radish in the JA Irumano jurisdiction is produced to meet a wide range of uses, such as japanese white radish with leaves, root vegetables, and spicy radish. Mainly shipped from Kawagoe City, Tokorozawa City, Miyoshi Town, Iruma District, Sayama City, etc. The origin of radish is said to be from the Mediterranean coastal region to Central Asia. It seems that it was already cultivated in ancient Egypt more than 4000 years ago. It came to Japan from the southern part of China around the 8th century. It has been widely cultivated since the Edo period, and it seems that pickles and dried daikon radish were processed as preserved foods, and planting was encouraged as a measure against hunger and as a nutritional supplement. In addition, since it has been produced nationwide for a long time, there are many varieties unique to each region. For example, Nerima Daikon (Tokyo), Miura Daikon (Kanagawa Prefecture), Miyashige Daikon (Aichi Prefecture), Shogoin Daikon (Kyoto Prefecture), Moriguchi Daikon (Osaka Prefecture), Sakurajima Daikon (Kagoshima Prefecture), etc. The one named after has been cultivated. The characteristics of radish with strong pungent taste, which can be collectively referred to as pungent radish, are that the meat is hard and has little water, and it contains a lot of pungent ingredients of radish. It seems that there are even pale red and purple varieties. They have inherited the characteristics and unique characteristics of each region, such as those derived from old native radishes, those that have been handed down in detail by self-cultivation, and those that have been selected and bred from wild species. There seems to be something. Among them, a variety called mouse radish is well known because its appearance is bulging, it is a compact japanese white radish, and its roots are thin and long, so it resembles the tail of a mouse. Nowadays, it is said that Nezumi radish in Sakaki Town, Hanishina District was introduced as a medicinal herb from Nagasaki in the Edo period in Nagano prefecture. Is expressed. Similarly, in Omi Province (Shiga Prefecture), the daikon radish in the Okubo district of Ibuki Town, Sakata District, at the foot of Mt. It seems that it was. Also, because it is shallow in the soil, it is kicked and dug up, so it is also called “Kekkara-daikon”. I’ve heard that it doesn’t produce pungency except in this area of calcareous soil. Looking back to the Edo period of the Tokugawa Shogunate, there is no example of writing “karami-daikon” in Chinese characters, and it seems that you do not come across “karamidaikon” as a general term. It seems that each of them has “Karami Daikon”, “Musashi Daikon”, “Naratsumi Daikon”, etc. as one of the many radish varieties in the area. Looking at the inside of the jurisdiction, the western part is a mountainous hilly area connected to the Chichibu Mountains, from which the Oppe River, Korai River, and Iruma River flow eastward and join the Arakawa River, and the eastern part is a deposited fertile paddy field. From the central part to the southern part, it seems that it is a field area on the Iruma Diluvial Upland in the Kaji / Sayama Hills. In addition, it has abundant nature such as many archaeological sites, historic sites, castle townscapes and Oku Musashi Nature Park, and is an active material for people in the metropolitan area as well as in Saitama prefecture. About 24 years ago, around 1998, Mizuna greens were rarely cultivated in the Kanto region, and it seems that Kyoto Mizuna from Kyoto was sold as a high-class food in small quantities at fruit and vegetable departments such as department stores and mass retailers. Within the JA jurisdiction, thinking that his Mizuna greens from Saitama Prefecture could be stably supplied in 2001, it seems that the producer of 3houses planted the Mizuna greens subcommittee of the JA Irumano Kazumoto Co-Sales Liaison Council. Originally, bok choy was cultivated in the facility, but stable harvest can be expected by shortening the growing period by planting from seedlings and increasing the turnover rate of the field, and there is demand and the price is stable even in winter. Also, I heard that the cultivation was started from the point that it is not cultivated much in other production areas. When asked about the sales at that time, it was not well known in the Kanto region and there was an image that it was a high-class ingredient of Kyo Mizuna Greens, so it was rarely handled at general mass retailers, but it is not found in other crops. With its taste and crispy texture, it seems to have attracted attention because it is a new vegetable with a wide range of uses. After that, it seems that the way of eating has gradually become known by repeating sales promotion activities. Furthermore, as it was featured in TV commercials in partnership with a major food manufacturer, the popularity of mizuna greens increased at a stretch in the Kanto region, and it seems that the cultivated area and the number of producers increased as demand increased. It seems that the number of producers of the Mizuna greens subcommittee in the jurisdiction was 47 houses in 2015, and the cultivation area was 42 hectares. It is mainly cultivated in facilities using the greenhouse, and since it is cultivated in the open field from spring to autumn, it seems that it is supplying it on the anniversary. It seems that planting is done and the open field is cultivated by direct sowing. I also heard that they are cultivated 4 to 5 times a year, and the open fields are cultivated 3 to 4 times a year. We grasp the cropping situation and collect data, and utilize it for advantageous sales. In addition, since the cultivation management was different for each producer and the quality was also different, the subcommittee created a cultivation standard table from 2015 and summarized the processes from sowing to cultivation management, harvesting to shipping. It seems that they are trying to improve production technology and quality by sharing this with the members of the club. In addition, it seems that efforts are being made to eliminate variations among producers in shipped products by holding shipping product confirmation meetings. It seems that Taro, which has been handed down from ancient times in Japan, was originally cultivated in Iruma-gun, which is under the jurisdiction of JA. In the 1965s, JA worked on the spread of Taro in earnest, with the current main varieties “Dodare Taro” and “Hasuba Taro (a variety exclusively for Taro, with a slightly sweet taste and good taste). It seems that grandchildren grow better than potatoes and mainly eat grandchildren. By the way, the name lotus leaf is derived from the fact that the leaves do not hang down and become horizontal like lotus leaves.) ” It begins with the introduction of. In the 1975s, when the Iruma burdock, which is the main crop in the jurisdiction, suffered a continuous cropping disorder, it seems that it was widely cultivated in the jurisdiction by promoting the cultivation of the current mainstay spinach and Taro as its crop rotation crop. In the Sayama area, which is the main production area, it seems that the introduction of watering equipment has been promoted in 70% of the fields in the area from the beginning of the introduction of Taro in order to make it a strong production area against drought. It seems that the characteristic of cultivation in the jurisdiction is that high-quality compost is continuously put into the fertile land of Musashino, and green manure is cultivated and plowed after the Taro planting is completed. This is a soil preparation suitable for Taro cultivation by soil management, such as aggregate structure (excellent in ventilation, water flow, water retention, and good rooting) and good fertilization due to slow-acting nitrogen derived from compost. Seems to be doing. In 2013, the number of producers in the jurisdiction was about 435, and the cultivation area was about 167 hectares. The main cultivation areas are Tokorozawa City, Sayama City, Kawagoe City, etc. The shipping time is from October to March, and it seems that stable supply is provided by storage and shipping even after the severe winter season. In addition, regarding fruit selection and selection, under the strict inspection system by the subcommittee and JA, in order to differentiate from other production areas, each Taro is hand-made by humans, 6 grades in size of grandchildren, 2 in shape. We perform fine-tuned selection of grades and children’s potatoes in 2 grades and 10 grades in total. It seems that it is possible to propose products according to the application. In addition, the fruit sorting plant started operation in October 2020, which has led to a reduction in the working hours of producers, and I have heard from my acquaintances who are engaged that the relief is spreading.
