Photochromism refers to the phenomenon in which a single chemical species reversibly forms two isomers of different colors under the action of light without changing the molecular weight. Also, two isomers are molecules with different properties. Succeeded in creating a hexatriene-based photochromic compound that undergoes a cyclization reaction with 100% stereoselectivity and a compound with a ring-closing quantum yield of almost 1. In addition, in the biradical-generating photochromic compound HABI, which suppresses dissipation, we created an ultra-fast photocoloring and decoloring reaction system. Utilizing two-dimensional microphase separation due to photoreaction of liquid crystal polymers with azobenzene side chains, we succeeded in optically controlling the morphology and orientation of thin films. We created a light-driven polymer motor that converts light energy directly into mechanical energy using an elastomer film containing azobenzene. In addition, we succeeded in controlling the planar asymmetry by photoisomerization reaction, and controlling the magnetism and superconducting properties of metal nanoparticles and thin films. We will discover new systems of photochromic single crystals and fibers capable of photoreversible shape control. We present the mechanism of reversible deformation of diarylethene single crystals by light, the estimation of generated stress, and the possibility of light-driven actuators. In addition, we succeeded in optical control of water repellency and hydrophilicity of the surface of diarylethene single crystal, and optical control of metal deposition selectivity on the thin film surface. Furthermore, as one of the ultimate performances, we have achieved control of photocoloring/photobleaching with single-wavelength light using multiphoton absorption.

On February 28, 2022, Mr. and Mrs. Suzuki, who are persimmon farmers living in Ishimaki, Toyohashi City, won the Minister of Agriculture, Forestry and Fisheries Award at the National Fruit Tree Technology and Management Contest. This competition honors advanced farmers who can serve as models for others in terms of fruit tree production technology and management. It seems that the couple, with their foresight, will provide support with a view to the future so that they can pass on the technology to the younger generation that will follow them.

【名前の由来】
It seems to have been named after the Goku-Wase variety of persimmon, which matures early.
【主な特徴】
According to NARO, "Soshu persimmon'' is an early maturing sweet persimmon grown by crossing "Izu persimmon'' with "109-27 persimmon'' ("Okitsu No. 2 persimmon'' × "Okitsu No. 17 fruit tree''). The fruit matures at about the same time as "Wase Nishimura persimmon", and has a good taste and a deep taste. The fruit shape is flat and easily disturbed, and the fruit weight is about 250 g. The flesh is slightly soft and dense, and has a good taste with a lot of juice. The sugar content is 14-15%. As a Wase variety, it has a good shelf life, and can last for about 12 days in the growing area (Akitsu Town, Higashi-Hiroshima City, Hiroshima Prefecture). There are almost no stale fruits, and some soiled fruits are produced, and it seems that most of them are caused by striations in the cultivation area. In addition, the vigor of the tree is moderate, and the tree shape is open. Male flowers do not grow. The flowering period of the female flowers is almost the same as that of 'Izu persimmon' and earlier than that of 'Fuyu persimmon'. Epiphysis of female flowers is common. Both parthenocarpy and seed formation ability are not high, and there seems to be a tendency for early fruit drop. New shoots tend to grow secondary in June, Colletotrichum acutatum, Gloeosporium sp. Increases in the rainy season. At first, black circular lesions appear, which gradually spread to dark brown, become elliptical depressions, and appear to have vertical cracks. In fruit, young fruits are black and round from around the rainy season. In the coloring stage, the disease becomes active again, and at first small black spots appear, and then it seems that the lesions become circular or oval and slightly depressed. It seems that mucilage (mass of spores) of salmon food tends to form on new shoots and lesions of fruits after rainfall, etc. Also, when the petiole is infected, the upper part is blackish brown. The plant overwinters in lesions, buds, fallen leaves, etc. on the old canopy.From around the end of April, spores are formed on these. The spores are rainwater. It scatters with droplets of, reaches soft shoots and young fruits, and seems to invade and develop from the epidermis. Spores are formed on newly formed lesions, and secondary infection occurs one after another. If the temperature is 20 to 27°C and the humidity is high, a large amount of spores are formed, and the disease repeatedly develops on shoots and fruits. In particular, when there is a lot of rainfall in May and June, there are many diseases on young branches and young fruits, and when there is a lot of rainfall in September and October, the damage to the fruits is severe. There is a difference in the onset of the disease depending on the cultivar. Fuyu persimmon and Hiratanenashi persimmon are weak, Saijo persimmon and Jiro persimmon(A type of astringent persimmon with a square shape and no seeds.  It is known by other names in various places, such as Niigata's Hacchin, Yamagata's Shonai persimmon, Sado's Okesa persimmon, and Tanenashi.)are moderate, and Koshu Hyakume persimmon and Yotsumizo persimmon(Astringent persimmons grow wild from Shizuoka Prefecture to Kanagawa Prefecture. It is a special product of Nagaizumi Town, Sunto District, Shizuoka Prefecture.)are strong. In addition, it seems that it is likely to occur in poorly drained gardens and densely planted gardens with poor ventilation). Taishu persimmons are characterized by their crunchy texture and high sugar content, and are highly trusted and popular. This year, due to the bad weather in early spring, there was concern about the growth of the persimmons, but it seems that the persimmons have a beautiful color and luster. Persimmons are bright orange and Despite its bright orange color, this excellent produce, which is in season at this time of year, is green. Recently, more and more people know about It may have a ripe color that makes you hesitate for a moment. Until you try it once, you may not pick it up even if you see it. That's why I'm writing today to introduce the original goodness of Japanese agricultural products and skilled farmers so that people around the world who see my blog will know about it. On March 28, 2022, JA Toyohashi of Toyohashi City held the "Jumbo Eggplant Contest" for the first time to compete for the weight and thickness of eggplants by variety and department in order to boost the cultivation of special eggplants. In the weight category, 615 grams of eggplant, which is equivalent to the usual five eggplants cultivated by Mrs. Suzuki, has won the championship. Kansuke Hakuto Peach (Wase Peach, which was registered as a variety in 1981 because of the branch of Aichi Hakuto Peach. It is slightly larger than "Aichi Hakuto Peach", the skin is well colored, and the flesh is juicy and sweet. , And sold as "Kansuke peach") and other peach producing areas, the shipment of wase varieties has started in the northern part of Toyohashi city. It is blessed with good weather this season, but it rains moderately, and it seems that the fruits are big and sweet. On June 22, 2022, the current chairman of the JA Toyohashi Peach Subcommittee, who harvested "Misaka Hakuto Peach", said, "It's plump and big, and the sugar content is 12 to 13 degrees, which is sweet and delicious. Say he's talking proudly. Under the slogan of "making delicious peaches," the group members are actively exchanging information with each other through cultivation classes, etc., and are working to improve cultivation techniques. It is expected to ship about 5,000 cases (5 kg per case) this season, and is scheduled to be shipped to Aichi prefecture, mainly in Nagoya. In Toyohashi City, you can buy peaches that have just been shipped at the direct sales office "Fruit Shop Yume-Sai Hall" attached to JA Toyohashi's general collection and shipping area in Ishimakihon Town. It is very popular. It seems that the shipping time is until the beginning of August. Kansuke Yamamoto was born in August 1500 in Kamo Village, Mikawa (currently Kamo Town, Toyohashi City). At the age of 25, he climbed Mt. Koya in Kishu, incubated at Marishitendo, and then toured the countries. His journey covers a wide range of areas such as Shikoku, Sanyo, Sanin, Kyushu, Osaka, Kyoto, and Sakai. It is said that he became a vassal of Mouri and Amako at one time (the truth is unknown). The officer to Shingen of Kai's tiger is estimated to be around 1543. He became a samurai in command of a troop of foot soldiers with a tipend 100 presence and orderly 25 people due to the Suwa attack from 1542 to 1544, but after various achievements, he later became a samurai general (esp. During the Sengoku) with 500 presences. You have been promoted to period). A Sengoku warrior who survived until October 18, 1561. It originated in India today and is cultivated in China around the 5th and 6th centuries. It was introduced to Japan around the 8th century. It was introduced to Europe in the 13th century and in North America in the 16th century, and it seems that it was not as important as other vegetables. Is it from a beautiful outline? In the Edo period, the technology to make the first eggplant in a little bit started. It seems that the shogunate issued a ban because it was bought and sold at such a high price. When it was introduced to Japan, it was called Kunlun Purple Gourd (Indian Purple Gourd). Cultivation begins under the name “Rangoku Eggplant” in the Shosoin document of the Nara period. It seems that it has reached the present with a semi-forced pry that it is converted from good taste in summer to “make” and “live” and is auspicious. The harvest time and season are from July to October. The decisive difference from the eggplants on the market is the green stems and calyx. It is a place where there are few seeds, the flesh is tight, and it does not easily crumble. It seems that there are 180 varieties of eggplant in Japan, probably because it has been cultivated in Japan for a long time. By the way, it is said that there are more than 1000 varieties in the world. In addition, all members of the JA Toyohashi Eggplant Subcommittee have been certified as “environmentally friendly farmer (as recognized by law)” by the prefecture, and are working hard to cultivate safe and secure eggplants. Procedures for farmers to use the Eco Agricultural Products Mark: As an eco-farmer, certified by the prefecture, Create an “eco-agricultural product mark use permission application” and submit it to the Agriculture and Forestry General Office. It seems that the application form is also available for printing from the website and for the Agriculture and Forestry General Office. Procedures for farmers' groups to use the Eco Agricultural Products Mark: As an eco-agricultural promotion group, it is certified by the prefecture. Next, prepare an “eco-agriculture promotion group certification application” and submit it to the Agriculture and Forestry General Office. It seems that the application form is also available for printing from the website and for the Agriculture and Forestry General Office. Procedures for distributors to use the Eco Agricultural Products Mark: Create an “Eco Agricultural Products Mark Use Permission Application” and submit it to the Prefectural Production and Distribution Division. The application form is printed from the homepage and is also available at the Prefectural Production and Distribution Division. Mark creation after receiving permission to use the eco-agricultural product mark: Farmers and eco-agricultural promotion organizations or distributors who have received permission to use the eco-agricultural product mark create their own marks. In order to maintain the uniformity of the mark design and color, the prefecture distributes the design sheet free of charge along with the license. Obligations of those who have been licensed to use the Eco Agricultural Products Mark: Those who have been licensed to use the Eco Agricultural Products Mark must: Creation and storage of related documents such as signboard installation in fields or sales facilities, production / shipment records, subdivision records, and mark management records. Toyohashi City is recruiting farmers to participate in the matching program from September to October 2022. It seems that the target audience is farmers in the Toyohashi area, JA, agriculture-related business companies, local support organizations, and others who are interested in new ways of agriculture and solutions to their own agricultural problems. In addition, it seems that it will recruit startups from all over the country to solve the problems faced by farmers in the city. Under the title of "Creating Future Agriculture", the city has started a demonstration development project "TOYOHASHI AGRI MEEETUP" through co-creation between startups, local farmers, and companies, aiming to create agricultural innovation. “Toyohashi City, Aichi Prefecture”, Born on August 1, 1906 as the 62nd city in Japan(Futagawa-juku Station (Toyohashi City, Aichi Prefecture)). Although it is a region, the east borders Shizuoka Prefecture with the Yumihari Mountains as the border. Facing the Pacific Ocean to the south and Mikawa Bay to the west, it is blessed with abundant nature and a warm climate. The center is dotted with facilities such as the city hall, yoshida(Fumonji Temple (Toyohashi City) (Toyohashi City, Aichi Prefecture): Yoshida Shichifukujin)castle, and art museum. It seems that the shopping district is developing around Toyohashi Station. A tram (city tram) runs from the station front to the eastern part of the city, and is popular as a means for citizens. In the eastern part, Imou Bog, known as small Oze in the Tokai region, is located in the eastern hills. In the south, the farmland cultivated during postwar days bears abundant vegetables and boasts the highest agricultural output (gross agricultural production) in Japan. The Omotehama coast, which faces the Pacific Ocean, is known as the spawning ground for loggerheads(Caretta caretta (Linnaeus, 1758): Widely distributed in the world ocean. The coastlines of Japan's Honshu, Shikoku, Kyushu, and Okinawa are attracting attention as the only spawning grounds in the North Pacific Ocean. The body color is brown on the back, pale yellow on the abdomen, and the head is large.). Mt. Ishimaki rises in the north, and many are hilly areas. A region where fruit trees such as jiro persimmon, which is famous for “Ishimaki”, strawberries, peaches, and grapes are cultivated. Beautiful flower irises(Acorus calamus var. angustatus: sweet flag)bloom in early summer at the northernmost tip. January 4: Toyohashi Flower Festival (Toyohashi City). Aichi Prefecture's cabbage production in 2016 was the second highest in Japan. Above all, the area from Toyohashi City to Atsumi Peninsula is positioned as a major production area. Efforts of Mr. Koshiro Sugiura, who was the head of the vegetable shipping union in Takashi Village, Atsumi District (currently Toyohashi City) in 1930. Thanks to his efforts, the excellent variety “Koshi Kanran(Cabbage)” was born. After that, it will gradually be cultivated in neighboring Okubo, Tahara Town and Akabane Town. It is said that this area has become a production area that supplies large consumption areas in the east and west. In 1966, winter cabbage became a designated production area of the country, and actively worked on improving cultivation techniques. In 1968, Toyogawa irrigation water was introduced, and the production volume increased dramatically. It grows well in warm and abundant sunshine, and is characterized by good taste and freshness. The cultivated area at that time was about 1100 ha in the fall and winter, and about 500 ha in the spring and summer. Expansion of scale and anniversary of cultivation progress, acreage is on the rise. It is roughly divided into four types according to the time of year, and the main products are winter (cold ball) and gold sour (spring type), which are shipped in the fall and winter. In winter, the leaves are flat with few wrinkles, and the leaves are hard and chewy. It is used for cooking because it does not easily crumble even when cooked. Gold sour (named in Toyohashi: spring) is often used for raw food such as julienne because the leaves are wrinkled and round in shape and the leaves are soft. In recent years, sorghum(green manure: High production is expected and germination is good. Moreover, the seed price is cheaper than Crotalaria(Juncea). It tends to be relatively easy to use because it is relatively responsive to the acidity of the soil.)has been used to improve drainage and fertility. It's said that there is a border in Toyohashi City, Aichi Prefecture, that divides the two different ways of cooking sukiyaki between the Kanto and Kansai regions. 国指定 : 重要文化財 - 東観音寺多宝塔(Myoshin-ji School of the Rinzai Sect-行基) - 小松原-1907年5月27, 豊橋ハリストス正教会 聖使徒福音記者マトフェイ聖堂 - 八町通-2008年6月9日, 豊橋公会堂 - 1998年9月2日, etc. A long time ago, Ushikawa people(Pleistocene)lived 50,000 to 80,000 years ago. May 1957 at the limestone quarry in Ushikawa town -Discovered some of the human humerus. It is considered to be the oldest fossil hominid found in Japan. In the 600s, the “穂” country changed to Mikawa. “Perilla”, It is an annual plant of Lamiaceae and resembles Green shiso; Japanese basil. Perfect for health, the Jomon people were processed into cookies. “Kuruma shrine tumulus(Ueta Town)” : Prefectural designation (registration) 1959, Kofun period : CAR shrine, A 42 m-long front-rear burial mound located on the river terrace along the left bank of the Umeda River in the southern part of the city. In September 1885, when the rear circle was flattened for the renovation of the main shrine, three copper bell apricot leaves, one glass magatama, 33 jasper tube balls, one iron sword, and one Sue pottery bottle were found. It is estimated that the main body of the mound where the relics were excavated is a horizontal hole type stone chamber, but the details are unknown because the main shrine is built on the flattened surface. Of the excavated items, two of the harness decorations, Suzu Kyouha, are complete products, one is crushed but the bell part remains, and all three are three bells with bells on the tip and both sides. It seems that you can see that it was an apricot leaf. This Suzu Kyouha is rarely excavated and is the only obvious example of an excavated tumulus in the prefecture. It is a relatively old harness and is chronologically edited from the latter half of the 5th century to the first half of the 6th century even in the latter part of the Kofun period. In addition, glass magatama is also rare and has a red color. Since these have been stored at the car shrine without being dissipated from the time they were excavated, they are designated collectively. The front part of the mound remains well, the front part is 14 m wide, 24 m long, 2.8 m high, and the diameter of the rear circle is 18 m. “Ueta Town” : Our association consists of a total of 28 members and 10 designated suppliers, centered on Higashi Mikawa, in the Toyohashi area (15 people), the Toyokawa area (1 person), the Atsumi area (9 people), and outside the area (3 people). In addition, all of us members who handle agricultural products in the production area will provide information on consumers' understanding of food and the safety and security of food. And we are making efforts to ensure a stable supply of fresh local vegetables and fruits that we love. Tower of Peac: In memory of the war dead and the victims of air raids who believed in the victory and prosperity of their homeland and dedicated their precious lives, praying for permanent peace in the world, and praying for peace so as not to repeat the tragedy of the war again, 1965 As a project to commemorate the 20th anniversary of the end of the war in September, the Toyohashi City Peace Tower Construction Support Group was organized and built with the cooperation of the general public. "Taishu persimmon'' was developed in 1977 at the Akitsu Branch of the Fruit Tree Experiment Station (grape and persimmon research base) (Higashi-Hiroshima City, Hiroshima Prefecture). It is said to be a sweet persimmon cultivar bred by crossing persimmons ("Okugosho persimmon" × "Hanagosho persimmon"). Since 1989, it has been registered under the systematic name of "Akitsu No. 10 persimmon'' and in 1994 as "Kaki Norin No. 7'' and has been published. In the following year, 1995, it was registered as 'Taishu' based on the seed and seedling law from the former name registration variety. It is a sweet persimmon with very large fruits that can be expected to be harvested around the same time as the Wase Matsumoto Fuyu persimmon. Those with "stripes" tend to have a higher sugar content. Also, according to NARO, it is expected to spread widely in sweet persimmon production areas. It can be cultivated west of Chiba Prefecture on the Pacific Ocean side, and west of Niigata Prefecture on the Sea of ​​Japan side, but it seems that it may remain astringent in cold highlands where the temperature does not rise sufficiently in summer. There were 349 producers in the JA Toyohashi Persimmon Group in 2020, of which 348 farmers were producing Jiro persimmons. In addition, Nishimura persimmons, Soshu persimmons, Aishuho persimmons, Fuyu persimmons, and Yoho persimmons(Application number (Application date) Publication date Registration number (Date of Registration) Duration of Breeder's Rights, 3819 (31 March 1990), 1 January 1900, 2888 (November 19, 1991), 18 years
(Expiration date: November 20, 2009) Crossing combination old strain name Fuyu persimmon × Jiro persimmon, crossing year: 1967 Kaki Akitsu No. 6. It is a completely sweet persimmon, and requires high temperatures in summer and autumn to naturally remove astringency. Agriculture and forestry certified variety (former name registered variety), registration number: Kaki Norin No. 4. Moderate vigor, many female flowers, and low early and late fruit drop, resulting in high productivity. Appearance is good because there is little contamination. When the seeds are formed, a minute crack occurs at the apex of the fruit, and it seems that it tends to turn black from there. Due to the high parthenocarpy, seedless cultivation seems to be desirable to prevent blackening of the fruit apex. The sugar content of the fruit is about 16-17%, and the flesh is a little hard, but when it is fully ripe, the juice will increase and the taste will improve.)are also produced, but 198 ha (88%) of the total production area of ​​226 ha is Jiro persimmon farms. It seems that Toyohashi's Jiro persimmon is still the main product of persimmon farmers. The Jiro persimmon brand of Toyohashi was created as a result of the pioneering persimmon farmer's long-term promotion in the Kanto market and the accumulation of tasting events at the sales floor. Farmers in Toyohashi, such as those who were engaged in sericulture, seem to have changed to persimmon farmers in the 1955s when the economy deteriorated. Originally, Wase Jiro persimmon, which can be harvested from mid-October, spread around Toyohashi as a branch change (breed improvement) variety of normal Jiro persimmon that can be harvested around November in Mori Town, Shuchi District, Shizuoka Prefecture. I hear. At that time, persimmons from Gifu prefecture were shipped to the Nagoya market in Aichi prefecture, and persimmons from Nara and Wakayama prefectures were shipped to the Kansai market. Therefore, Toyohashi persimmon farmers aimed at the Kanto market, and farmers in Toyohashi City, Toyokawa City, and Shinshiro City jointly formed the Higashi Mikawa Fruit Tree Association, and jointly built fruit and vegetable farms in Toyohashi City and Shinshiro City to ship. In this way, it seems that even before the Higashi Mikawa Fruit Farm was established, individual farmers spared no effort in shipping persimmons from Toyohashi Station by JR Freight. Jiro persimmon seems to be the reason why the market trusted it because there were few fruits in the Kanto market. Furthermore, after the establishment of the Higashi Mikawa Fruit Tree Association, it seems that Toyohashi's Jiro persimmon has become a brand because it succeeded in arranging a certain amount as a production area. However, it has become difficult for the Higashi Mikawa Fruit Tree Association to operate with only farmers, and it seems that 17 years ago, the fruit and vegetable farm in Shinshiro City was transferred to JA Aichi Higashi, and the fruit and vegetable farm in Toyohashi City to JA Toyohashi. Good persimmons contain more ascorbic acid than citrus fruits. This C6H8O6 (discovered in 1753 by James Lind (1716-1794), a British naval doctor, as a preventive factor for scurvy) and tannin excrete alcohol in the blood, and the diuretic action of abundant potassium helps to sober up. It is expected to have a great effect on hangovers because it promotes. In addition, sibol, a type of tannin contained in persimmons, has the effect of strengthening blood vessels and lowering blood pressure. I forgot to mention that Jiro persimmon cultivation has a long history. It borders on Shizuoka Prefecture to the east. It is located in the southern part of Yana District, and the name of the village comes from Mt. Ishimaki, which has an altitude of 358 m. The summit of Mt. Ishimaki is made up of huge limestone rocks, and the Ishinomakiyama limestone plant community around the summit is designated as a national natural monument. It looks like one side. As a mountain that can be easily climbed, it is popular among people of all ages, so it is worth paying attention to.
