In order for Yamanashi Prefecture to develop original varieties, in 1991, at the Yamanashi Prefectural Fruit Tree Experiment Station (Yamanashi City), “Soldam Plum” was crossed with “Black Butte Plum”, and the plums were selected and cultivated from the seedlings. Because it is harvested and shipped in the summer.

At the end of June 2022, JA Fruit Yamanashi union leader Nakazawa was appointed as the new president of JA Yamanashi Chuokai. The new chairman has expressed his intention to work on “1JA” that integrates eight JAs in Yamanashi prefecture into one. Agricultural production in the prefecture in 2021 was very strong, mainly for fruit, but there are concerns about soaring fuel and materials and securing fertilizer in the future. There are many big issues, so we will work together as one. According to the new chairman, there is no doubt that each agricultural cooperative is in a difficult situation to aim for the integration of eight JAs in the prefecture in order to strengthen the management base, and it is necessary to strengthen the agricultural cooperatives. It seems that the eight agricultural cooperatives will focus on considering how to operate from the same standpoint by grasping the business situation. A maximum temperature of 40 ° C was observed at 6 points for the first time in the history of observation. From the end of June 2022, the maximum temperature has continued to be close to 40 degrees Celsius, mainly in the Kanto Koshin region, and on Friday, July 1, there were many places where the heat level increased. Yesterday, the maximum temperature until 16:00 was 40.4 ℃ in Kiryu City, Gunma Prefecture, 40.3 ℃ in Isesaki City, Gunma Prefecture, 40.2 ℃ in Katsunuma, Koshu City, Yamanashi Prefecture, 40.1 ℃ in Hatoyama Town, Saitama Prefecture, Kumagaya City and Tajimi City, Gifu Prefecture. Observed 40.0 ℃. Kiryu City, Gunma Prefecture, Isesaki City, Gunma Prefecture, Katsunuma City, Koshu City, Yamanashi Prefecture, and Hatoyama Town, Saitama Prefecture were the hottest in July. In Japan, it will be extremely hot on May 30, 2022. In Koshu City, Yamanashi Prefecture, it seems that the maximum temperature of 34.1 ℃ was observed, which is approaching the hottest day. It seems that it was a summer day of 27.8 ℃ even in central Tokyo. Also, on June 10, the acceptance of tourists from overseas is scheduled to resume for the first time in two years from 2020. Under these circumstances, a forum was held at the end of May in Kofu City, Yamanashi Prefecture, where travel agencies from all over the country gathered. The forum was opened by an association of about 5,600 travel agencies nationwide, and seems to be the first to be held in Yamanashi. While about 900 of his tourists from all over the country participated, prefectures and municipalities introduced Yamanashi’s special products such as wine and cherries and VR that allows you to experience the virtual real world of climbing Mt. Fuji to attract tourists. It seems. Agriculture has multiple functions such as national land, environmental conservation, and living environment as well as food supply. Looking only at the food supply aspect, it is possible to improve productivity by using chemical fertilizers and chemically synthesized pesticides. However, if too much chemical fertilizers and pesticides are used for that purpose, soil and rivers may be polluted and the ecosystem balance may be disturbed. It is certain that it can go around and adversely affect human health. “Environmental conservation type agriculture” is a sustainable agriculture that takes advantage of the material circulation function of agriculture, paying attention to harmony with productivity, and reducing the environmental load by using chemical fertilizers and pesticides through soil preparation. The use of chemical fertilizers and pesticides can pollute the land and destroy the ecosystem. It is good to plant cover crops (green manure) during the period when the crops are not cultivated for sustainable agricultural production in harmony with the environment. “Conservation Oriented Agriculture” : Organic farming, natural farming, alternative farming, low-input sustainable farming, etc. are included, but from the strictest standpoint of pesticide-free and chemical-free fertilizer cultivation, the use of chemical materials is not permitted at all. , There is a range to the position of reduced chemical fertilizer. The national government enacted the Sustainable Agriculture Law in 1999 to provide support by lending agricultural improvement funds to certified farmers and providing special measures for taxation of agricultural machinery. In addition, the law states that “agricultural production method with high sustainability” is “a rational agricultural production method that is recognized as contributing to the maintenance and promotion of the productivity of agricultural land derived from the nature of soil and other favorable farming environments.” Defined, specifically, technology related to the application of organic materials such as compost that has a high soil improvement effect, technology related to the application of fertilizer that has a high effect of reducing the application of chemically synthesized fertilizers, control of weeds and pests, etc. Among the technologies related to this, the ones that are highly effective in reducing the use of chemically synthesized pesticides are listed. GAP is an acronym for Good Agricultural Practice, which is usually translated as Good Agricultural Practice or Agricultural Production Process Management. GAP is like ISO (International Standard) and means the norms of production process control and hygiene control such as whether pesticides are used correctly, safe fertilizers are used, and they are washed with clean water. In addition, an agricultural management entity recognized as having cleared these norms by examination by a third-party organization can obtain GAP certification. Since GAP is a norm for process control, it is expected to have the effect of preventing problems and facilitating the investigation of the cause, compared to conventional result control. The country of origin of peaches is China, and it is said that they were introduced to Persia on the Silk Road, to Greece and Rome around the 1st century, and to the Americas in the 17th century. Nectarines are a family of peaches, but unlike peaches, the skin has no hair and the whole is shiny, so they are also called oil peaches and hikari peaches. In Japan, according to Kojiki and Nihon Shoki, native species already existed in the Yayoi period, and it seems that they were eaten in the Heian period, but in the Meiji period, they were watertight eastward from China. Peach (Tianjin and Shanghai) was imported, and the mutation gave birth to a white peach species peculiar to Japan. “Summer Butte Plum” is a plum variety grown by crossing “Soldam Plum” with “Black Butte Plum” and “Summer Angel Plum” by crossing “Soldam Plum” with “Kelsey Plum”. Both varieties mature in late July, are large balls, have a high sugar content and have a good taste. Again, this is a plum that was bred by mating Soldam Plum and Black Butte Plum at the Yamanashi Fruit Tree Experiment Station in 1991. The variety was registered in 2005. Currently, it is considered to be an original variety of Yamanashi prefecture, and the production rate in Yamanashi prefecture is the highest, and it seems that it accounts for more than 90% of the total production rate. The size is as large as about 170 g because it was developed with the aim of creating a plum with a large ball and good taste. The pericarp is lilac and the flesh is pale yellow. The juice is abundant and juicy, and the flesh is chewy. The taste is very sweet and has a moderate acidity. Yamanashi Prefecture has the largest cultivation area and yield of “Japanese plums” in Japan. Yamanashi Prefecture has a long history of plum cultivation, and it is fresh in our memory that records of cultivation in the Ochiai district of the present Southern Alps city have been recorded since the Edo period. Colored red when the sun hits. The flesh is pale yellow and the flesh is dense. It is loved as a variety with low acidity and strong sweetness. “Kurokawa Gold Mine” is located in Enzan-kamihagihara, Koshu City, Yamanashi Prefecture, and prospered during the Mr. Takeda era. It reached its peak in the middle of the 16th century and was called Kurokawa Senken, but it declined in the 1570s and became an abandoned mountain.There is a mountain called Mt. Tosaka（Altitude: 2,115 m）in the mountainous area east of Yamanashi Prefecture, which is the headwaters of the Tama River. Sleeping in the forest of Kurokawa Valley on the east side is the ruins of the gold mine of “Kurokawa Senken”, which is said to have supported the military funds of Mr. Takeda Sengoku / Muromachi. It is a deep mountain that is rarely visited now. The scale of the mining town is 600 m above and below the valley of Kurokawa, and the maximum width is 300 m. The excavation area was only one-third of that of this vast archaeological site, but tunnels, ore crushing workshops, gold melting workshops, managers’ residences and tombs, etc. were confirmed, and the mining town’s efficiency was improved. It seems that the structure has been clarified. Various relics reminiscent of life at that time-earthenware, ceramics, copper coins, kisel, kanzashi, swords, scissors, flint, fishing hooks, go stones, gunballs, powder mills, tea mills, stone Buddha pedestals, and five-wheeled towers have been excavated. Estimating the age of the mining town from earthenware, it surely appeared in the first half of the 16th century and disappeared in the middle of the 17th century. The heyday is the era of Harunobu Takeda (Shingen) , as the legend says. However, it is speculated that it was not directly managed. In recent years, the excavation of archaeological sites and joint research on history using ancient documents have become active, and it is said that this cooperation was particularly successful in the survey of Kurokawa gold mine. The results of the excavation at the site of the ruins seem to be in good agreement with the rise and fall of this mining town, which was estimated by connecting fragmentary ancient documents. Such a poor tool stand shows that special mining tools were not yet developed at that time, and gold mining and refining were started by trial and error. Fortunately, the ore in this mine contained pure gold grains in the quartz veins, which enabled the refining of gold by such a primitive method. The fact that the final gold melting work was done in small groups also means that the Kanayama people (the miner who collected gold at the gold mine in the Takeda territory during the Warring States period. He was active as an engineer unit by leading the Kanehori people. There were quite a few gold mines in Kurokawa gold mine, Yunooku gold mine, and Tambayama gold mine. Kurokawa Kanayama people have 12 surnames of Tanabe, Nakamura, Furuya, Yoda, Kazama, Hosaka, Hoshina, Ohno, Ikeda, Ashizawa, Tagusagawa, and Fukasawa.）In addition to that, it seems that it shows a medieval aspect different from the specialized mine management in the early modern period. The mine, which declined rapidly at the end of the 16th century and left by the influential Kanayama people, no longer produced gold in the Edo period, and the remaining gold digger made a living by undertaking civil engineering work. However, the technology developed here was applied to mines around the world and contributed to transforming Japan in the 17th century into one of the world’s leading producers of gold and silver. The SADO gold mine magistrate in the early Edo period was occupied by successive Koshu natives, and the success of Shigeemon Nagata from Kurokawa in the irrigation work is said to have applied the technology born at this mine to paddy field development. The Jomon pottery at the Tonobayashi site was excavated in Enzan, Koshu City, Yamanashi Prefecture. It is located on the edge of the plateau on the south side of the right bank of the Monju River in the northeastern part of the former Enzan city. The Shigerohara and Kitahara ruins are known in the vicinity. Designated as a cultural property in 1988. Mid-Jomon period, height 72 cm, caliber 56 cm. A beautiful and well-proportioned pattern. The rim of the mouth has a series of arcs, and the striations running vertically on the body and the curves that draw a large arc are extremely deep. In the past, it seems that it has been exhibited overseas in Italy, France, the United States, Malaysia, etc. It was discovered in 1962, buried in an inverted position.
