After the scholar Ranzan ONO explained in 1808 that “potatoes are 馬鈴薯,” potatoes came to be called potatoes. He is from Kyoto in the large Scholar of herbalism in the late Edo period. Sugita Genpaku, Kimura Kenkado, Iinuma Yokusai, Tani Buncho, Sakurada Kinsai, Mizutani Toyobumi, Mitani Kouki, Kariya Ekisai, Yoshida Ritsusen, Yamamoto Moribii (the great-grandfather of Prime Minister Gonbei Yamamoto during the Taisho era). Nowadays, it is generally called potato, but it seems that the name “potato” is used in academic societies and government. “Potatoes” are derived from the fact that they resemble a bell attached to a horse’s neck.

Due to the invasion of Ukraine, there are voices from producers of “hand-stretched fine white noodles” in Minamishimabara City, Nagasaki Prefecture, who are concerned about the soaring price of wheat flour. It is imported from the United States, Canada, Australia, etc., but the market price of grains is skyrocketing due to supply instability, and producers and cities seem to be watching the world situation. It seems that all the parties concerned are tightening their minds to take measures such as increasing the ratio of direct sales, which makes it easy to pass on the price increase. According to Minamishimabara City, Nagasaki Prefecture is the second largest production area after Hyogo Prefecture, and seems to be the second largest producer in Japan. It seems that about 240 companies are currently producing in the city. According to the commercial wheat price revision guide for producers, in June 2021, “Bread flour / wheat flour whose protein contain is from 10% to 12% flour”, which is mainly used as a raw material for bread, is 110 yen per 25 kg, noodle. “All Purpose flour / soft wheat flour”, which is the raw material of the product, was 80 yen, but in December, “Bread flour / wheat flour whose protein contain is from 10% to 12% flour” was 315 yen, “medium”. “Power / weak wheat flour” jumped to 345 yen. Furthermore, on March 9, 2022, the Ministry of Agriculture, Forestry and Fisheries will raise the average price of the five major brands that sell imported wheat to flour milling companies in the first half of 2022 (April-September) by 17.3% from the previous quarter. Has announced. It seems that the main factor is that poor harvests in North America pushed up the international market. This is a significant increase following the 19% increase in the second half of FY2021. Nagasaki Prefecture is located in the westernmost part of the mainland, in the northwestern part of Kyushu. It has a prefecture area of 213 km east-west and 307 km north-south. A major topographical feature is that about 80% of the land consists of peninsulas and islands, and the land is rich in undulations, so it seems that the land is scarce. The average annual temperature in the northwestern part of the Shimabara Peninsula, which is the main production area of potatoes, is 15.7 degrees Celsius, and the annual rainfall is 2300 mm. It is an area with a long frost-free period from early April. In addition, many typhoons approach and land, which can cause enormous damage to agricultural products, and it is said that farming is carried out under severe land and weather conditions. In the prefecture, the spring potatoes, which are called “new potatoes” in the market and are shipped from April to June, seem to start harvesting starting from Fukue Island in the Goto Islands. It seems that it will move to the northwestern part of the Shimabara Peninsula and will reach the end in the Iimori district of Isahaya city on the opposite bank. I heard that all of them are cultivated in warm regions facing the sea. It is said that Nagasaki Prefecture’s potatoes entered Nagasaki Port from Java (now Indonesia) in 1598 by the Dutch. After that, I heard that it has been cultivated all over the country while being used as a famine crop during several famines. According to records since the beginning of the modern era, about 500 ha was cultivated at the end of the Meiji era, and it seems that the largest area was 2987 ha in 1945 and 8570 hectares in 1954 immediately after the end of the war. However, from the following year, it started to decrease, and it is said that it will be 4000 ha in 2013. Cultivation is divided into five cropping types, mainly in the autumn cropping from September to December and the spring cropping from March to June, which can secure the optimum temperature for growth, resulting in five cropping patterns, and the harvest is in November. It seems to be mid-June of the following year. Autumn cultivation is mainly cultivated on the Shimabara Peninsula, and the shipment volume is about 5,500 tons. Since it is cultivated in the open field, it is easily affected by the drought in autumn, and the yield is small due to the time of the typhoon, so the crop seems to be unstable. Autumn mulch cultivation seems to be cultivated in the warm areas of the Shimabara Peninsula, where the first frost is delayed. The shipment volume is about 4500 tons. Winter tunnel cultivation is mainly cultivated on Fukue Island, and the shipment volume is about 300 tons. Previously, it was actively planted on the Shimabara Peninsula, but it seems that it has shifted from tunnels to non-woven solid coating due to the inability to secure yields for the labor and cost. At the southern tip of the Shimabara Peninsula, which is the main cropping type of the prefecture and is a frost-free area, it seems that the harvest is from late April to mid-June when the rain falls. The shipment volume was about 37,000 tons in 2015. Since the yield is affected by frost damage, it seems that a non-woven solid coating is used as in winter crops in order to secure a stable and early shipment volume. Since it is cultivated twice a year in spring and autumn, unique varieties suitable for double-cropping in warm regions are cultivated. In 1971, the high-yielding and tasty “Dejima” was cultivated in both spring and autumn, and in 1978, the extremely high-yielding “Nishiyutaka（In 1970, at the Nagasaki Prefectural Agriculture and Forestry Center Aino Potato Center, artificial mating of “Dejima” as a mother and father “Chokei No. 65” was carried out (Saikai No.15). In 1978, it was registered as a variety as “Bareisho Norin No.23”. Suitable for warm southwestern regions, excellent in fertility. Expected to grow and harvest in spring and autumn（Since the crops were swollen and the yield was high, the cultivation increased rapidly especially in spring mulching since 1985.）The flesh is pale yellow and the flesh is moist. The leaf color’s dark green, which is slightly darker than “Dejima”. The leaflets are a little thick inside and reach a little sparse. 「Plasmodium resistance major gene: Epidemic resistance leading gene」Ralstonia solanacearum（bacterial disease of eggplant: To provide a bacterial wilt disease resistant inducer which contains a compound indicating resistant induction activity against a bacterial wilt disease as an effective component, and a bacterial wilt disease prevention method using the compound. -Patent Office）, Bacterial soft rot（soft rot pathogen: To provide a mass production method of seed potato seedlings, capable of preventing rot and soft rot of a rooting zone to increase probability of survival, and mass-producing at one time nondisease seed potato seedlings capable of increasing percentage of rootage when planting.

Somewhat weak resistance. However, the field resistance is quite strong. Since there’s little dehiscence of potatoes and little breakage of foliage due to the wind, it’s widely suitable for the second cropping area in western Japan.）” was cultivated, and it is said that it is now the main variety of round varieties. On the other hand, as soil diseases such as Spongospora subterranea and Pseudomonas solanacearum, and resistant varieties such as Globodera rostochiensis, “Aiyutaka（According to the Ministry of Agriculture, Forestry and Fisheries variety registration, this variety was bred by crossing “Dejima” with “Chokei No. 108”. The potato shape is oval, the skin color is white yellow, and the flesh color is pale yellow. Potato cyst nematode It is a variety suitable for cooking with resistance. The flora is slightly upright, the individual weight type and the number type are slightly individual weight type, the stem length is short, the thickness is medium, the stem color (primary color) is green, the number of branches is slightly small, and the leaf color is The density of green and leaflet is medium, the number of hair mushrooms on the leaves is small, the number of flowers is rare, the flower color (primary color) is reddish purple, the flower color (secondary color) is white, and the distribution is even. The length of the branch is a little short, the depth of the potato set is a little shallow, the length of the potato is a little long, the flatness is weak, the shape is oval, the skin color is white-yellow, the rough skin is slippery, the eyes The depth is extremely shallow, the flesh color is pale yellow, the dormant period is a little short, the dying period is medium, the early hypertrophy is a little fast, the upper potatoes are quite heavy, the number of upper potatoes is medium, and the average weight of one upper potato is a little. Large, slightly sticky to medium flesh, medium resistance to Y mosaic disease, weak resistance to epidemic field, and putative genotype of potato cyst nematode resistance is H1. Compared to “Digima”, it has a shorter stem length, a reddish-purple flower color with white stripes, and a potato cyst nematode resistance putative genotype（Derived from the strain “CPC1673” cultivated in the highlands of South America, “Atlantic”, “Aiyutaka”, “Sayaka”, “Toya”, etc. have the “Rx”1 gene: Potatoes.） of H1, so it is compared with “Nishiyutaka”. Then, it is said that the distinction is recognized by the fact that the flower color is reddish purple and white stripes are included, the rough skin of the epidermis is slippery, and the putative genotype of potato cyst nematode resistance is H1.）” was cultivated in 2002 and “Sanjumaru（The origin of the variety name is that it has three excellent characteristics: “resistant to pests”, “high yield”, and “good appearance”. Announcement of variety registration application in August 2010.）” was cultivated in 2010. May queen is cultivated in spring crops and seems to ship about 8,000 tons from mid-May to June. The annual sales amount varies greatly depending on the year, and it seems that it is an item with large price fluctuations, but the handling volume has remained relatively stable at 40,000 to 50,000 tons in the past 10 years (as of 2015). Seems to be there. This is because more than 80% of the handling volume utilizes ALIC’s designated vegetable price stabilization business, so risk management when the market selling price falls functions and reproduction is secured. This seems to be because it greatly contributes to the maintenance of production area and quantity. The shipping period is from November to July, and the main shipping time is from May to June. It seems that the occupancy rate of Nagasaki potatoes in the Tokyo Metropolitan Central Wholesale Market in 2014 was 46% in May and 56% in June, and 72% in May and 82% in June in the Osaka Central Wholesale Market. “Shimabara Unzen Japan Agricultural Cooperatives”, The Shimabara Peninsula（138.3 km around the southeast of Nagasaki Prefecture and 459.36 km area occupies 11.2% of the whole prefecture. The Unzen Mountains at the center and a gentle hill area approximately 24 km east-west and 32 km north-south. Mt. Fugendake: 1,359 m, It consists of a plain extending along the coast, and the annual average temperature is mild at 16 ° C.Some areas are frost-free. It’s blessed with 2,000 mm of annual precipitation, 2,200 hours of sunshine per year, and weather conditions.）, which is in jurisdiction, is blessed with natural conditions such as soil and weather conditions. Shimabara City, Located at the eastern end of the Shimabara Peninsula in the southeast. It covers an area of 82.96 km2 and occupies about 18% of the Shimabara Peninsula. In the center is a sloping land that extends to the Ariake Sea on the east side centering on Mt. Mayu (elevation 818.7 m). There is a large-scale collapse trace in 1792 on the eastern slope, and many Nagareyama are distributed from the lower part of the collapse to the sea area around Kujuku island. Behind it is Unzenhugendake, which erupted in 1990 for the first time in 198 years. The lava dome was named “Heiseishinzan” in 1996. The number of farm households accounts for 24% of the prefecture as a whole, and the amount of agricultural output accounts for about 43%. Shimabara City is a representative agricultural area（Recent data）. It is a relatively warm area, and although there are paddy fields in the coastal area, upland fields occupy more than paddy fields. Around the Miebard upland field, radishes, carrots, Chinese cabbage, ginger, lettuce, watermelon and other open-field vegetable production areas are formed. Fruit vegetables such as tomato in the summer and house ginger are cultivated in institutional cultivation, and a typical complex management is carried out. Cross-item management stabilization measures target only at eligible and ambitious “principal farmers (certified farmers and village-based farming organizations that meet certain conditions)”, for the stabilization of their farm management, unlike conventional stabilization measures devised for individual commodities of all farmers. It is certified as an Eco farmer and is also working on the Nagasaki Prefecture version of GAP（Sustainable agricultural management for the future as well for environmental protection sustainable. We should ensure that natural resources are managed properly in order to make agricultural development-Ministry of Economy, Trade and Industry-Support was provided for initiatives to secure the trust of consumers and stimulate domestic markets by such means as improving the quality control of food products through the introduction of HACCP practices and adoption of ordinary hygiene control in the food industry, rigorous compliance, and voluntary labeling of places of origin of ingredients in accordance with guidelines.（ハサップ : Hazard analysis important control points）: Support will be provided to small and medium food manufacturers, etc., by organizing human resource development workshops and providing technical information in order to further promote the improvement of control of food manufacturing processes (through hazard analysis and critical control point (HAACP) procedures).）. For management, a field ledger is created and soil analysis is carried out for each stroke. We will work on soil improvement and fertilizer application design in light of past data, and strive to reduce fertilizer to the level of special cultivation. Conduct a planting survey in advance to ensure planned and stable shipments. The Seven Wonders of Shimabara（The exit and entrance, the name of the town is just the opposite.）are wonders taught in Shimabara (the entertainment area in Kyoto City). 島原のシマバライチゴ自生地 – 南千本木町 – 1960年3月22日 : The vine of this strawberry is thin and strong, and extends to a length of 5 m. Also, the thorns of the vine entangle with other things and climb up. It is so overgrown that you can’t even set foot in the colony. It blooms in autumn, and tufted, sour fruits ripen red in winter. “Minamishimabara City”, Blessed with a warm climate, moderate rainfall and sunshine hours, it is famous as an area where agricultural products can be easily cultivated. Located in the southeastern part of the Shimabara Peninsula, in the southern part of Nagasaki Prefecture. It borders Shimabara City in the north and Unzen City in the west. Facing the Amakusa area of Kumamoto prefecture across the Ariake Sea, I am deeply moved by the memories I visited once. It has a land containing fertile and abundant groundwater that extends south from the foot of Mt. Unzen, which exceeds 1,000 m. It also has a coastline that faces the Ariake Sea and Tachibana Bay, which are rich in seafood. Agriculture, forestry and fishing are carried out by the residents. Historically, there was a time when Christianity was introduced to this area in the 1560s and Christian culture prospered. The Edict expelling Jesuit missionaries was a prohibition document concerning the mission of Christianity and trade with Spain and Portugal issued by Hideyoshi TOYOTOMI in Chikuzen Hakozaki, in July 24, 1587 : There are many historical heritage sites in the city that show the light and shadow of Christianity in Japan. 1637: Shimabara-Amakusa ikki (Shimabara War): The Shimabara War broke out, lasting two years from 1637 to 1638. In such a situation, the occurrence of Shimabara / Amakusa uprisings led the bakufu to the complete prohibition of Christianity and the complete national isolation that allowed only bakufu-controlled trade. “Hara Castle Ruins” is “Hidden Christian-related heritage of Nagasaki and Amakusa Region” : Registered for UNESCO World Cultural Heritage on June 30, 2018. The shimabara peninsula area has been certified as the first in Japan by the global geopark networks, which is said to be the geological version of the world heritage（Unzen Volcanic Area Geopark: In 2009, with Itoigawa in Niigata and Mt. Toyakousu（Lake toya Mt.usu）in Hokkaido）. An area where you can feel the heartbeat of the earth and the history of the earth. “City designated cultural property”, Uchiishibashi group（Kitaarima Town）: It was built from the late Edo period to the early Showa period. About 10 arch bridges made of natural stones and cut stones are left in the Arima River system in Kitaarima Town. The construction of the arch bridge requires a high level of technology because the strength of the stones is maintained by the weight of the stones. Natural stones are used for most of the stone bridges such as wall stones. At first glance, it looks like a rough structure, but in reality, it requires more skill to combine stones that are not standard products. I hear that the biggest advantage is that it is relatively easy to procure materials. Since the bridge is also a part of the living road, it requires quick repair. It can be said that the skillful skills of the masons closely supported people’s lives. The scenery where the stone bridge is in harmony with the river and fields is also beautiful. We will support the cultivation of ‘Bananas’, which are expected to be new high-profit and high-value-added crops. Liability Company（LLC.）, which develops business by utilizing subsidiary aid. We received 100 seedlings from company limited, an agricultural corporation that grows bananas in Kagoshima and Saga. ‘Freeze-thaw awakening method’ : By freezing and thawing growing cells for half a year and applying special treatment, resistance to cold and diseases becomes stronger. The Banana applied this time is pesticide-free and does not use pesticides or cleaning agents, so the skin is thin and the whole skin can be eaten. The sugar content is 25 degrees, which is much higher than the general 15 degrees, and is characterized by its rich sweetness and mellow aroma. About 150 trees can be harvested from one tree, and mature bananas are scheduled to be harvested around the summer of 2021. When it was transmitted, it was around last fall and before my favorite winter. ‘Arima Christian Heritage Museum’ -南有馬町 – The background behind the 250 years of Christianity’s hiding : The process leading to the suppression of Christianity, 1637 : Shimabara-Amakusa riot (Shimabara War) situation is displayed in an easy-to-understand manner. Hei, Minamiarima Town: Seibo Park is an art park that exhibited works in the birthplace of Seibo Kitamura（Graduated from the sculpture department of Tokyo Fine Arts School (currently Tokyo University of the Arts) in 1912. His career In 1908, “Indignation” was selected for the first time at the 2nd Art Exhibition (Bun Exhibition) of the Ministry of Education. He has been exhibiting every year since then, and the 10th “Evening Bell” will be the chief of choice. In 1919 he became a judge for the Japan Fine Arts Exhibition and formed the Hibarasha in the same year. He was a professor at Tokyo Beauty School from 1921 to 1944, and became a member of the Imperial Academy of Fine Arts in 1924 and a member of the Japan Art Academy in 1947. He specializes in heroic human figures, and before the war he worked on equestrian statues of military personnel and statues of great men. After the war, he became a central member of the Japan Fine Arts Exhibition sculpture department, focusing on peace and freedom. In 1951, he was requested by Nagasaki Prefecture to build an atomic bomb monument at the hypocenter of the atomic bombing, and in 1955 he completed the “Nagasaki Peace Memorial Statue”.）, a sculptor who was born in Minamiarima Town, Minamishimabara City and is famous for the creator of the Nagasaki Peace Memorial Statue. In the wooden memorial hall where the garden and the birthplace were restored, about 60 works such as “Peace Statue”, sculptors, books and paintings are exhibited, and you can see the condensed essence of Seibo art. It seems. Also, from the park with a good view overlooking Amakusa Nada, you can see the nationally designated historic site “Hara Castle Ruins” known for the Shimabara Rebellion. “Unzen City”, It is located in the south, northwestern part of the Shimabara Peninsula. Tachibana Bay（Tachibana-wan Bay was originally called Chijiwa-nada Open Sea or Chijiwa Bay, but in 1919 when TACHIBANA’s statue was constructed in Chijiwa Town (present Chijiwa Town, Unzen City, Nagasaki Prefecture), the persons concerned submitted a petition to change the denomination of Chijiwa-nada Open Sea to Tachibana Bay.） faces the west bank and the Ariake Sea faces the east bank. The total area is 214.31 km2, which occupies 5.2% of the whole prefecture. Some are designated as Unzenamakusa National Park, the first national park in Japan. The climate is blessed with warm and rainy conditions, making it one of the prefecture’s leading tourist destinations. Seven towns were merged in 2005. Kojirokoji (Unzen City, Nagasaki Prefecture): Important Preservation District for Groups of Historic Buildings. Tachibana-wan Bay was originally called Chijiwa-nada Open Sea or Chijiwa-wan Bay, but in 1919 when TACHIBANA’s statue（Mr. Shuta Tachibana（陸軍歩兵中佐:正六位-勲四等-功四級）: He was a lieutenant colonel and worked as an educator for Emperor Taisho.）was constructed in Chijiwa Town (present Chijiwa Town, Unzen City, Nagasaki Prefecture), the persons concerned submitted a petition to change the denomination of Chijiwa-nada Open Sea to Tachibana Bay. Similar Ushioni festivals or cow god festivals are also held in the following places: Minamitakaki County, Nagasaki Prefecture (present-day Unzen City); Uwajima City, Ehime Prefecture; and Ichiki-cho, Hioki County, Kagoshima Prefecture (present-day Ichiki-kushikino City); under the name of ‘Toshimon,’ ‘Ushonin,’ and ‘Tsukuimon’ respectively. Finally, I think the excellent varieties such as “Wase Haraguchi（early ripening: In 1969, nagasaki prefecture Nishisonogi District Saikai Town: Current Saikai City（Even today, they sometimes set shorobune afloat on rivers or on the sea in Shimabara City, Saikai City, Matsuura City, and Goto City.）” : In the Miyagawa early mandarin orange field of Mr. Seiji Haraguchi in the mountains, only one tree that bears extremely sweet fruits was found.）and Sasebo Wenzhou（長崎県佐世保市の「尾崎次夫」氏の圃場に於いて,「宮川早生」の15年生樹から, 枝変わりを確認し, 1975年（昭和50年）に発見された。1993年（平成5年）には, 長崎県果樹試験場において, 茎頂接ぎ木による, Virus‐free: Once infected, plants cannot be excluded from immunity and cannot escape the virus for the rest of their lives; ウィルスの無毒化を行い, 1998年（平成10年）には, 長崎県内のミカン産地へ苗木分譲が盛んになった。11月下旬から, 12月上旬に収穫期が見込まれ,「宮川早生」よりも10日程遅い,（早生）, 中生種として名高い。） are wonderful. Very early harvesting:「岩崎早生」,1968年（昭和43年）, 長崎県西彼杵郡西海町中浦南郷(現: 西海市)の「岩崎伝一」氏が, 圃場で「興津早生」の枝変わりとして発見 ; This is a bud mutation of Okitsu-wase found by Denichi IWASAKI of Saikai Town, Nishisonogi District, (today’s Saikai City,) Nagasaki Prefecture in 1968. The history of Nagasaki mandarin is that in 1780 (Tenmei era), Omura feudal lord, Sumiyasu OMURA-Ko, Satsuma feudal lord “Nagashima mandarin” (Izumi District (former: Higashimachi) Nagashima-cho Wenshu mandarin), Ikiriki, Sonogi District. It is said that it started to be cultivated by Mr. Yuemon Tanaka, Mr. Rinemon Tanaka, Mr. Tsuguemon Nakamichi and others in the village (currently Tarami Town, Sonogi District).（Citrus Unshiu has heard that the seeds brought back from China by the envoy to Tang China began to bear fruit and were found in Kagoshima.）The saplings were shipped nationwide when the high-quality “Satsuma mandarin” was cultivated from the Ikiriki region. This is called “Ikiriki Citrus unshu”. In 1876, mandarin oranges were sold by hand in the castle town. In addition, from around 1887, the production area of mandarin oranges was expanded in Ikiriki Village, and even today, the area is the main production area in Nagasaki Prefecture. From 1961, “Act on Special Measures for Promotion of Fruit Tree Agriculture (Government Ordinance No. 145)”, the Nagasaki Prefecture Citrus Promotion Plan was formulated, and the citrus cultivation area is rapidly increased throughout the prefecture. Demand for fruit trees in Japan is generally declining and stagnant, and there is a growing tendency for small quantities to be sold as other items and for good quality. Many fruits, including mandarin oranges, are in overproduction. There are increasing demands from other countries to expand imports of fruits and fruit products. In order to achieve sound development, it is necessary to deal with the overproduction trend of fruits. Induce production that responds to trends. Fostering independent fruit tree farmers who can be the core players in the production area. And it is necessary to further strengthen the constitution of fruit tree agriculture. The system for promoting fruit tree agriculture was strengthened（Partial amendment of Law No. 15, July 1, 1985）. To the prefectural governor, the then Vice-Minister of Agriculture, Forestry and Fisheries（角道謙一氏, After retiring, he will assume the post of chairman of the Norinchukin Bank.）. In 1597（Tensho 7）, Nagasaki was the first onion to land in Japan by a Portuguese ship. The production of early-maturing onions is thriving, and it has a good reputation for its freshness and good taste. I hear that potato was introduced from Jakarta to nagasaki by a Dutch ship in 1598. It boasts the second largest production volume after Hokkaido, and Minamishimabara City is one of the leading production areas in the prefecture. Cultivation started in earnest in the Meiji era, and now it is cultivated based on two crops, spring and autumn, taking advantage of the warm climate. Asparagus officinalis was introduced to Nagasaki as ornamental from the Netherlands during the Edo period. There are spring and summer seasons, and spring asparagus grows slowly over time, so it has a strong sweetness and is rich in minerals and especially vitamin C. Summer asparagus has a beautiful light green color because it grows at a stretch due to the blessings of the daytime sun, and it is soft to the vicinity of the root. I hear that the bright red tomatoes were introduced to Nagasaki from the Netherlands at the end of the 17th century.
It seems that the arrival to Japan began around 1600 AD when a Dutchman who had Jakarta as a base for oriental trade loaded potatoes on a ship and brought them to Nagasaki, and was called “Jagataraimo”. After the introduction of Nagasaki, many famines occurred from the 17th century to the 19th century. Seems to have been tried. Nagasaki Prefecture has the second largest production of potatoes after Hokkaido. However, during the Edo period after the introduction of potatoes, there were not many records of cultivation in Nagasaki prefecture, and it is believed that they were cultivated only slightly. Cultivation began in earnest after the Meiji government, and statistics seem to remain from 1883. Since it was intended for foreign residents in the early Meiji era, it seems that it was limited to cultivation in Nagasaki city. In the middle of the Meiji era, exports began to be carried out mainly in Southeast Asia, so it seems that the production area was formed around the Nishisonogi Peninsula around Nagasaki Port.
Tuff loam suitable for the climate is indispensable for making potatoes on the Shimabara Peninsula. In fact, the volcanic ash that had accumulated due to eruptive activity in various parts of the Shimabara Peninsula from 1.5 million years ago changed into soil over time, and it seems that it came to be called because the iron content of the component was red and rusty. Since it was originally volcanic ash, it contains an appropriate amount of minerals such as Fe and K, and it seems that it has been carefully used as a soil suitable for the growth of potatoes. Exports of Nagasaki potatoes to Hong Kong and the Philippines began in the Taisho era, and it seems that full-scale cultivation has begun on the Shimabara Peninsula to cover the amount.
At the end of January 2022, even though potatoes were suffering from corona, the unit price per kilogram remained at a high level because Hokkaido, the largest production area in Japan, was poorly harvested due to bad weather. Shipments from Nagasaki Prefecture are the third largest in Japan after Hokkaido and Kagoshima Prefecture, and more than 70% of them are from the Shimabara Peninsula. In 2019, Nagasaki Prefecture produced 79,200 tons, of which Unzen City produced the largest amount, 37,100 tons. The unit price of potatoes handled by JA Shimabara Unzen is 106 yen in 2019, and it seems that the prices in 2020 and 2021 are more than double that. However, due to the light rain since mid-August in 2021, the shipment volume in December is less than half of the usual year, and I hope that it will recover quickly in the middle of March of the following year.
