【主な特徴】
The wars that unfolded in Europe, Asia, and the Pacific were initially dominated by Japan, Germany, and Italy, but the Allies, with their large economic and military power, gradually caught back. Italy and Germany surrendered in 1943, and American forces concentrated their attacks on Japan. In 1945, the Allied Forces demanded Japan’s unconditional surrender, but Japan refused and dropped atomic bombs on Hiroshima and Nagasaki in August of the same year. The Soviet Union also invaded Manchuria and Korea. After the war, he carried out meaningless occupation of the Northern Territories. After that, Japan decided to surrender with the Potsdam Declaration, and on August 15 of the same year, Emperor Showa announced the surrender to the people on a radio broadcast (Gyokuon Hoso; Hirohito Emperor surrender broadcast), and World War II ended with the victory of the Allied Forces. Declaration of Humanity（新年ニ當リ誓ヲ新ニシテ國運ヲ開カント欲ス國民ハ朕ト心ヲ一ニシテ此ノ大業ヲ成就センコトヲ庶幾フ）: A common name for Emperor Showa’s edict issued in the official gazette on January 1, 1946 in Japan under Allied occupation. As a defeated country, Japan was forced to withdraw its soldiers from the occupied territories and lose the colonies it had acquired since the Sino-Japanese War. In addition, Okinawa, the Ogasawara Islands, and the Amami Islands will be under the control of the United States, and the Northern Territories will be under the control of the Soviet Union. In Japan, homes and factories were destroyed by air raids, prices rose sharply, and many people became unemployed. ポツダム宣言《民主主義的傾向の復活強化》『日本外交年表並主要文書』.

He has built a unique style of painting, such as flowers, birds, and human figures, and has gained great popularity. After moving to Tokyo, he became a Western-style painter Seiki Kuroda. He later studied under Kokei Kobayashi, a Japanese-style painter born in Joetsu City. Although he was selected for several Teiten and Inten exhibitions, he left painting for a while and lived a life of eating at an old temple in Nara. After that, he spent nearly 60 years devoted to painting until his death.) introduces the world of his works. In mid-October 2022, we will celebrate his 120th birthday as a special exhibition. “Bando City”, Located in the southwestern part of Ibaraki prefecture. It was born on March 22, 2005 by the merger of Iwai city and Sahima town. It borders Noda City, Chiba Prefecture across the Tone River（This is the Tonegawa, also known as Bandotaro. The River Tone meanders [winds its way] through the plains of Kanto）. The center is a flat land called Sashima tableland, with rice fields and upland fields spreading out: Famous for its many flatland forests and the arrival of swan（Every year from late October to mid-March; Cygnus columbianus, Platalea leucorodia, Anas acuta）, rich nature is preserved-Sugao Swamp etc. Located on the border between Bando and Joso. A long and narrow swamp with a north-south width of about 5 km and an east-west width of about 200-500 m. Egawa River, Iinuma River, Higashinire River flow in. Water flows from the Hoshido lock to the Tonegawa River via Sugao Swamp. The sorimachi bank is called kaminuma and shimonuma in border, and walking load is maintained in kaminuma. Pacific climate with an average annual temperature of 15.3 degrees celsius: A relatively warm region with annual rainfall of 1,288 mm. Bando City has a mild climate throughout the year and flat terrain blessed with groundwater, making it suitable for growing vegetables. Lettuce and summer green onions are branded vegetables designated by Ibaraki Prefecture, and are highly popular due to the trust of consumers, boasting top-class production volume nationwide. In addition, Ibaraki Prefecture’s brand tea “Sashima green tea（In 1859, it was exported overseas for the first time, and it seems to have been counted as an important export item along with raw silk. Today, it is a famous tea with a rich aroma and richness that is known nationwide.）”, which is produced in the city, is said to produce a rich flavor, aroma, and richness when processed. Since ancient times, it has been transported to Edo using the water transportation of the Tone River and has been loved by many people. At the end of the Edo period, when the black ships arrived, Japan started to trade with other countries. There is something deeply thoughtful about the fragrant tea, which has a long history as “the first tea that crossed the sea in Japan.” A place related to hero Taira no Masakado who won the eight Edo-period provinces of Kanto (Sagami, Musashi, Awa, Kazusa, Shimousa, Hitachi, Kouzuke and Shimotsuke) in the Heian Period. Called Bando’s Fengyunji, a wish to create an independent country beyond the power of the imperial court: Although branded as a rebel, he broke up with the aristocratic society here: A heart that I admire, trying to build an utopia for living with the people: It is alive in the places that Masakado loved. Iwai’s cantonment, home of the government, Kokuo Shrine built by the third daughter（如蔵尼）to mourn the soul, Enmeiin（神田山如意輪寺延命院-宗介, 来世法師; 真言宗智山派; 篠越山延命院観音寺, 本尊-延命地蔵菩薩）with a body mound, etc. The city is dotted with legends and historic sites. “Masakado Festival” held every November: A magnificent and gorgeous period picture scroll that seems to go back a thousand years is unfolded. “Masakado Half Marathon Tournament” to be held on the day: Many citizen runners participate and compete for good legs on the course related to Masakado. Forefront base for Go-Hojo Family’s expansion into North Kanto: Restoration while utilizing the remains of Sakasai Castle. It is popular as a historical park. Prefectural designated cultural property : 逆井城跡, 昭和60年3月25日指定, 逆井. The castle that remains today is a remains that made full use of the castle construction technique of the end of the Warring States period. He pursued prosperity with Nobunaga’s Azuchi Castle and Go-Hojo Family. In 1590, the castle was abandoned due to Hideyoshi’s conquest of Odawara. And now, more than 400 years later, the moat and earthworks as they were at that time are utilized. Former Iwai City is located in the southwestern part of Ibaraki Prefecture, roughly in the center of the Kanto Plain. It is located within 50 km from Tokyo, and is adjacent to Chiba Prefecture across the Tone River to the south. The topography is generally flat, and most of the geological features seem to consist of pleistocene fields and forests called the Sashima Hills. In addition, paddy fields open up in the alluvial lowlands of large and small rivers. The temperature is relatively warm with an annual average of 13.9°C, and the annual precipitation is around 1,200 mm. Based on these natural conditions, it seems that in the olden days, agricultural management centered on rice, barley, leaf tobacco, tea, and konjac was flourishing. In 1958, the Mefuki big Bridge opened over the Tone River, making transportation to Tokyo more convenient. Established as a main item of Today, Bando City plays an important role as a supply base for fresh vegetables to the Tokyo metropolitan area and local cities. In addition, lettuce, the main item introduced this time, is cultivated mainly in the western region of Ibaraki Prefecture, and it seems that it is cultivated twice a year: spring lettuce (March to May) and autumn lettuce (October to December). Many vegetable farmers mainly employ family labor, and their main crops are two crops of lettuce (spring and autumn) and green onions (summer). As an open-field leaf vegetable production area, it adopts an intensive farming system, and there are many specialized farmers even with a relatively small area of cultivated land (thick layer less than 1 ha). JA Iwai City does not have a section for each vegetable item, and it seems that producers who ship fruits and vegetables to JA are members of the Iwai Agricultural Cooperative Horticulture Section. Since 1998, Ho-Lettuce, which is a general system unified brand in the prefecture, seems to have used a special fertilizer with 50% organic fertilizer. Also, in order to produce quality products, it seems that production focused on soil preparation, such as adding compost, cultivating green manure crops (sorghum), and applying appropriate fertilizers based on soil diagnosis. In addition, in order to avoid continuous cropping failure, a crop rotation system such as lettuce (Asteraceae) sorghum (Asteraceae) long onion (Liliaceae) cabbage and Chinese cabbage (Brassicaceae) seems to be established. Furthermore, for traceability and environmental conservation agriculture, pest control using “hormone”, recording of “fruits and vegetables cultivation management ledger (fertilization / pest control diary)”, shipment of lettuce with no staple cardboard, discharge during lettuce packaging It seems that film scraps are being collected free of charge. One of the characteristics of the shipping system is the completion of the pre-cooling center in 1988, which established a unified sales system (lot expansion) and pre-cooled shipment (added value), and also collected cargo in order to realize early transmission of information (securing sales destinations). It seems that the time was set to 2:00 pm. The standard was simplified in 1995, and it seems that the standard that was divided into 12 classes until then was changed to 8 classes. Lettuce has a short harvesting period of 3 to 5 days and tends to be shipped intensively. I heard that the fruits and vegetables brought to the JA pre-cooling center are sorted by grade onto pallets, cooled to 5°C in a vacuum cooling system for about 30 minutes, and then shipped to markets in major cities on the same day. There are two types of lettuce production at JA: normal product (wrap regular), commercial lettuce by producer registration system (grouping), and high quality lettuce. Lettuce for commercial use is shipped in corrugated cardboard boxes for processing operations, and sales of naked lettuce (unwrapped) began in 1989. Since 2000, some of the lettuce has been connected to returnable containers. In addition, the price is set according to the season (spring and autumn), and the daily shipment volume is allocated to the producers every week. Commercial lettuce seems to be mainly used by large-scale lettuce farmers because it does not require the time and cost of wrap packaging and the price is fixed. High-quality lettuce production began in 1995 and was sold under the brand of ‘Meijin Lettuce’. Is produced by producers who have undergone a certain training course with the goal of reducing chemical fertilizers and pesticides cultivation, and uses organic fertilizers (80% organic fertilizer content) and soil preparation materials independently developed based on cultivation standards. It seems that the use of pesticides was kept to a minimum. In addition, they did not conduct quality inspections at the time of shipment, and if there were complaints from actual users, they would be expelled from the group. Celery is a relatively new vegetable that became popular in Japan around the 1955s. It seems to be cultivated in greenhouses in Shizuoka Prefecture in cold areas and from winter to spring. Celery cultivation began more than 50 years ago in the Nagasu district, a rural area facing the Tone River, in the former Iwai City, where the majority of producers adopt the management system of green onions and lettuce. It seems that the reason for this was that producers in the same area went to study under the late Mr. Jintaro Ito（Edogawa Ward, Tokyo: He started growing celery on his own in 1958, and 64 years ago, he passed away on July 6th, 2009.）, who was a pioneer of celery cultivation and was called the “god of celery.” After learning how to grow celery from a senior farmer who is said to be the most delicious in Japan, the “students of God” returned to their hometowns, and after that they formed a group called “Zensinkai” to work hard. Cultivation is greenhouse forcing and semi-forcing cultivation. Seeds are sown in July, and after 2 to 3 months of raising seedlings, harvesting begins in January of the following year. Celery needs a lot of fertilizer even among vegetables, but its roots have a weak ability to absorb nutrients, and it is also vulnerable to dryness. Apparently not. Once or twice during the seedling raising period, the seedlings are gradually replanted into large seedling pots, grown into large seedlings, and then planted in the field. The celery of Iwai Euro-American Vegetable Zensinkai is an intermediate variety (the most commonly distributed variety with light green stems, characterized by a refreshing aroma) “Cornell 619” and a green variety (with green stems). Cultivar with a strong aroma) ‘Summit’. All the producers are eco-farmers certified, and it seems that they are trying to do farming that does not burden the environment. They are particularly particular about the preparation of the soil, and have been actively applying compost made from cow manure and fallen leaves to create the optimal soil for their growth for over 30 years. Before planting every year, the members themselves conduct a soil diagnosis at the Bando Regional Agricultural Improvement and Extension Center, and based on the diagnosis results, all members discuss the results and determine the amount of fertilizer to be applied, mainly organic fertilizer, according to the condition of the soil. Regarding pest control, the use of pesticides is kept to a minimum, and in the summer when celery is not planted, the greenhouse is closed and solar heat soil disinfection is carried out to suppress the occurrence of soil pests and weeds. Ho-Lettuce was born in 1994 as a unified brand of JA Group Ibaraki. It seems that the producer’s desire to “make lettuce that consumers will fall in love with” is included. In addition to using JA’s original 70% organic fertilizer Ho-Koi Lettuce Premium, we pursue lettuce production with an emphasis on soil preparation, such as compost application, green manure plowing, and fertilization design based on soil diagnosis. In addition, JA Iwai produces Ho-lettuce twice a year, in spring (shipping period: February to May) and autumn (shipping period: October to December). Spring lettuce is cultivated inside plastic tunnels to protect it from the cold, and in order to grow crisp lettuce, the hem of the plastic tunnel is opened and closed every morning and evening to keep the daytime temperature below 20°C. In addition, since 2003, the JA has made it obligatory for producers in the horticulture committee to record the cultivation history of all agricultural products shipped. Producers record the implementation status of fertilization and pest control along with a GAP (Good Agricultural Practice: agricultural production process control) checklist. It seems that they are striving to ensure the safety and security of consumers’ food by preparing a system that can respond immediately to requests from business partners for disclosure of cultivation history. Lettuce loses its freshness easily, and in order to deliver it to consumers as it is in the production area, it is essential to make efforts at the production site and in the distribution process. JA Iwai established a vegetable pre-cooling center in 2020 to deliver fresh lettuce to consumers while maintaining high freshness. I have heard again that the fields are harvested the day before shipment. When removing the outer leaves, the producer leaves 2 to 3 more leaves than the shipping standard in order to maintain freshness. The lettuce brought in by the producer to the vegetable pre-cooling center is inspected, then sorted into pallets according to class, cooled rapidly to 5°C in a vacuum chiller, and then shipped to the market on the same day. More than 20,000 cases are shipped each day during the peak shipping season from March to April, and the staff at the pre-cooling center work quickly to ensure freshness.

Ibaraki Prefecture boasts the second largest lettuce production volume in Japan. Bando City, where JA Iwai is located, is characterized by flat land and a mild climate with an annual average temperature of 14°C. The same JA seems to have started growing lettuce in 1966. It goes without saying that they have carved history with their predecessors and greatly contributed to our food and health. Also, taking advantage of the location within 50 km from the Tokyo metropolitan area, the highly fresh lettuce is a barometer.
Ibaraki Prefecture boasts the second largest production volume of lettuce in Japan. JA Group Ibaraki’s “Love Lettuce” brand has been loved by everyone for 28 years. The four JAs in the prefecture (JA Iwai, JA Kita Tsukuba, JA Ibaraki Mutsumi, JA Joso Hikari) lettuce is at its peak in spring and autumn.
The former Iwai district is located in the southwestern part of Ibaraki prefecture. Bando City is known as a large producer of lettuce and green onions. It is under the jurisdiction of JA Iwai, and the large fields spread out on the plains as far as the eye can see, soothing the mind. In the Bando area, lettuce seems to be harvested twice, in spring and autumn. It is close to Tokyo and Kanagawa, Japan’s largest consumption areas, and it takes about an hour and a half by truck from the JA’s vegetable pre-cooling center to the logistics base in Tokyo, making it a model for urban suburban agriculture.
In the same JA jurisdiction, daily efforts are recognized, and production areas that have passed strict standards such as quality and safety are designated as “Ibaraki Prefecture Fruits and Vegetables Brand Producing Areas”. In the production process, we use a special fertilizer rich in organic matter, and we are particular about creating healthy soil and carefully selecting and pursuing high quality. Furthermore, since cultivation is thoroughly managed and recorded, you can eat with confidence. Chilling to around 5°C immediately after harvesting and shipping while maintaining freshness seems to be one of their commitments.
