【Major features】
Nagaya-mon Gate of the Ichiki Family: After the Battle of Sekigahara, Takaoka seems to have ruled by immigrating samurai from various parts of the Shimazu territory. In the Shimazu clan, it seems that the place where the samurai lived was called “Foot”. Takaoka foot, Mukasa foot, etc. still remain. The samurai gates at the foot of Takaoka Township are Nagaya-mon, Guanyin gate opening, and sliding door gate. Nagaya-mon has rooms on either side or one side of the gate. In Takaoka Town, this Ichiki Family Nagaya Gate is the only remaining gate, and it seems to have been designated as a tangible cultural property of the city. The date of construction is unknown, but it is believed to have been rebuilt after the Great Fire of 1858. The Ichiki family row house gate is an early form in which the height of the gate and row house ridges are different, and it seems to be valuable even today. The Ichiki family prospered as a martial arts family, with the 6th generation Zensuke becoming an instructor of the Shibukawa school of jujutsu in 1725, and the 12th generation Masanori becoming an instructor of the Shinkage school of swordsmanship between 1830 and 1844. Kamikuranaga’s Arithmetic Mound: It is located in the Kamikuranaga Autonomy Community Center and is called the “abacus mound.” 右側には,「明治廿四年二月十五日」（1891年）左には「豊後国竹田産 安藤新左衛門 代授 芳野久市」とあり. 孜々黽勉算學ノ蘊奥ヲ窮ム: It seems that he was able to reach the deepest part of mathematics because he studied diligently and diligently. Names include Soemon Hoshizaki, Ichinosuke Motozaki, Kinshiro Fukumitsu, Chojiro Ogakura, Manjiro Terasako, Kouemon Nagatomo, and Yonekichi Motozaki. This monument is believed to have been erected. Similarly, Shimokura Community Center also has a “Kagozuka”, and it seems that there were many people who studied mathematics in Musa at that time. Shimazu Tadakuni Birth Cedar: Musa Castle appears in historical materials during the period of the Northern and Southern Courts. The Shimazu clan entered the castle in the early 15th century. It seems that it was planted to commemorate the birth of Tadakuni, the ninth head of the Shimazu family, at Musa Castle. “Sangoku Meisho-zu Picture” (A document compiled by the Satsuma Domain in the late Edo period that describes the topography and famous places of the territory including parts of Satsuma Province, Osumi Province, and Hyuga Province. In particular, the history and buildings of shrines and temples First edition published in 1843, all 60 volumes), “This cedar has a circumference of over 3 feet (approximately 9 m), the distance between the two plants is approximately 1 m, and the roots and The trunk and branches are hugely lush, and they stand high, dozens of meters long (one length is about 3 m), and the branches and leaves cover only one step on the side…” is written. Apparently. The original cedar was destroyed in a fire in 1874, and it seems that what was planted around 1887 remains today. Soga Tomb: A five-part gravestone representing earth on the west side of Takaoka Elementary School, where Sukenari SOGA and Goro Tokimune of “Soga Monogatari” were held. It is not known when it was built, but the Soga Tomb in the prefecture says it was 1400 years old, so it seems that it was built when Takaoka was Ito territory. It is said that there used to be more than 60 Soga Memorial Graves in the prefecture, but now it seems that they remain in two cities and four towns. The Soga brothers killed Suketsune Kudo at the foot of Mt. Fuji for his father’s death, and he seems to be the ancestor of Mr. Ito Hyuga. The Ito clan was killed by the Soga brothers, but they are also related by blood, so it seems that the shrine was dedicated to appease the brother’s grudges. Takaoka Area Cultural Heritage (within the jurisdiction of the Takaoka Area Autonomous Region): The Takaoka area is a flatland-mountain castle located in Oyamada, Takaoka Town, Miyazaki City, Miyazaki Prefecture, which was part of Shimadzu-so in the medieval period. It is one of the three high castles of Hyuga, also known as Musa-in Takajo, and is designated as a national historic site. In the period of the Northern and Southern Courts, it seems that it was built as a territory under the direct control of Takauji Ashikaga, and Tadaaki Hatakeyama, a family member, served as Musa. Once dispatched to the castle, it becomes a base. Tadaaki, who went down to Hyuga, first took control of the Tsuchimochi and Kusakabe clans of Kunitomiso, and in 1338, he captured Sukehiro Ito and Moritada Nobe. In the following year, Kaneshige Kimotsuki, who was based in Gassan Hiwa Castle (Mimata-in Takajo), who was the most powerful, was subjugated and subjugated Hyuga. Hatakeyama entered Gassan Hiwa Castle and became Hyuga protection in 1345. In 1357, when they attacked Shibushi Castle, they were not only defeated by Ujihisa Shimazu (1328-1387: first head of the Oshu family, sixth head of the Shimazu family), but also the Southern Court. It is said that Takemitsu Kikuchi, who welcomed Imperial Prince Kanenaga, the son of Emperor Godaigo, attacked Musa Castle in November 1358, and Tadaaki Hatakeyama escaped from Hyuga to Bungo. Unknown), it prospered in the early modern period as a samurai settlement at the foot of the Satsuma domain, and it seems that various historical and natural cultural heritages were created in the rich nature. Takaoka is one of the outer castles founded by Yoshihiro Shimazu on his way back from the Battle of Sekigahara in 1600. Since then, a samurai community has formed at the foot of Amaga Castle. On the other hand, Musa is the area where the government office of Musa-in Temple is located and has become a base of politics and economy in the vicinity. embroiled in war. During the Edo period, it prospered as one of the outer castles of the Satsuma clan, and even now it seems that the remnants of a samurai residence remain. In Sakigawa, a checking station was set up as a key point on the highway of the Satsuma clan, and many cultural heritages such as the ruins of the checkpoint and the residence of the Futami family, who served as a staple of the checkpoint, remain. Wamyo Ruijusho-It is said that there was Emperor Jimmu’s imperial palace, and there are many folklore about the Emperor. There was a shrine called “Emperor Jimmu Shrine（The predecessor of MIYAZAKI Jingu Shrine）” for a long time-Imagine the origin of Miyazaki Prefecture. “Hyuga country” of the ancient Ritsuryo nation: It is believed to have been established between 684（Emperor Tenmu, Hakuho Earthquake: Estimated to be a huge earthquake along the Nankai Trough）and 696（Empress Jito）AD. Satsuma became independent from Hyuga in 702-Taiho Code, envoy to Tang. Furthermore, on April 3, 713, Osumi was separated. A country area close to the current MIYAZAKI area has been confirmed: Except for a part of the south. “Jinno-shotoki” – History book by Sir Chikafusa Kitabatake “Miyazaki Prefecture”, Located in the southeastern part of Kyushu, in a mountainous prefecture where mountains occupy about 75% of the prefecture’s land. The eastern edge faces Hyuga-Nada (Pacific Ocean) with a total length of 400 km. With an area of 70.2 km east-west, 160 km north-south, and a total area of 7,734.18 km2, it is the 13th largest in Japan except Hokkaido. The landform consists of mountains including Volcanic areas, and low flat plains and Basin that include foothills, plateaus, terraces, and lowlands. The distribution covers all areas except the plains in the eastern part of the central part of the prefecture. It is lined with mountains such as Mt. Sobo (1756 m), Mt. Kunimi (1739 m), and Mt. Ichifusa (1721 m)（With Oita and Kumamoto as the border）. The Wanitsuka Mountains are located in the southern part of the prefecture, and the Kirishima volcanic group centered on Mt. Kirishima (1700 m) is located on the border of Kagoshima Prefecture. In the northern and southern coasts of the prefecture, the mountain bodies are submerged in the sea, forming a rias-style submergent coastline. The hills and plateaus surround the Miyazaki Plain and the Kirishima volcanic group to the east of the Kyushu Mountains. Distributed in basin groups such as Kakuto, Kobayashi, and Miyakonojo. It is rocky or gravel, and the upper part is covered with white sand around the volcanic area. Rivers and rainfall erosion are significant, and terraces and dissected valleys have developed, presenting complex topographical conditions. In addition to the basin river valley, lowlands are found near coastal estuaries and in river basins in the plains, forming alluvial lowlands. I hear that straight dune coasts are distributed along the plain coast. The coastline is bordered by Mimitsu, with many bends in the north and straight sandy beaches in the south. It is blessed with an excellent natural environment such as lush mountains and a beautiful coastline, and the area of the natural park is 91,919 hectares, which occupies about 12 % of the prefecture’s land（Designated as a 105-hectare marine park area）. Forests are 5,873 km, 75.9 %, arable land is 690 square km, 8.9 %. Roadside landscape beautification ordinance, 1969: Protect excellent natural landscapes, trees and other plants along the road. By planting new flowers and trees, we plan to improve the scenery along the road and promote the beautification of the local area. “沿道自然景観地区（Eighteen districts, total 1,026 ha designated）”, Washingtonia filifera.（ワシントニアパーム）, “沿道修景植栽地区（Designated 74 districts, total 168）”, “沿道修景指定樹木（thirty-nine designated in twenty-seven locations）”, Designated, nationwide pioneer. The citizens of the prefecture have endeavored to create and conserve a road environment full of flowers and greens. 景観法（Landscape Act）, 2004, June 18, Law No. 110（Act No. 110 of June 18, 2004）, Examination of planting arrangement and management method that should be in the future. I hear that the first planting along the road was in 1937. Phoenix was planted along the national highway along the Nichinan coast, and maintenance as a road park began. National Park in Kyushu, Japan called Nippo Seaside National Park, 1955. Promoted the planting of flowers and trees along the road in 1962. Collaboration with citizens of the prefecture: We are working to improve the spirit of making our local road beautiful by ourselves and to foster an attachment to the road. “Kunitomi Town, Higashimorokata District”, Located in the central part of the prefecture, the east is adjacent to ‘Miyazaki City’, the prefecture’s capital. On the north side is Saito City, which is famous for its ancient tombs（Note however that the Haniwa (terra-cotta figurine) standing statue of an armed male currently owned by Tokyo National Museum was excavated from a site in the city of Ota in Gunma Prefecture, while the items excavated from the Higo Eta Funayama Tumulus, also owned by Tokyo National Museum, were excavated from a site in Tamana District in Kumamoto Prefecture, and finally the gilt bronze harness excavated from the ‘HYUGA’ Province Saitobaru Tumulus, now owned by the Gotoh Art Museum, was excavated from Saito City in Miyazaki Prefecture）. Aya Town in the same Higashimorokata District on the west and south sides. And a farmland village with an area of 130.63 km2 surrounded by Takaoka Town. It belongs to Miyazaki prefecture in 1873. In 1876, Miyazaki Prefecture was abolished and merged with Kagoshima Prefecture. In 1879, the Morokata District was established as an administrative district by the enforcement in Kagoshima. Belonged to this with the re-establishment of Miyazaki Prefecture in 1883. Honjo and Yatsushiro merged in September 1956 to form a new town. Furthermore, it merged with Kiwaki Village in March 1957. Then, Kunitomi Town was born as the largest town in the prefecture at that time. The origin is Kunitomi Honjo or: It is named after Kamihara-Miyako and Kunitomi-Honjo-Kamihara. The old Honjo Town used to be called Takahiramura or Kunitomimura. Toyokuni-Wakenomikoto has ruled Kunino-Miyatsuko for generations. This area was called Tenryo, and since then it has been under the direct control of the Shogunate（1646 : land directly controlled by Edo bakufu）until Meiji Restoration. Then, the town and village system was enforced in 1902. etc. Since the merger, the townspeople have cooperated.It has a spirit of harmony and cooperation in the blessed nature and climate. And great development in various fields such as education, culture, industry, economy, and environmental improvement. VEGETABLES-Peppers that are produced with all their heart are excellent in both taste and quality. Cucumbers are produced with great care in greenhouses. It receives warm sunlight even in winter and has a wonderful texture. We also produce Radish, Tomato, Green pepper, Shrimp-shaped taro variety, and Early-release bamboo shoots. FRUITS-Fuyu Kaki Persimmon（variety of sweet Japanese persimmon) : The taste and quality are outstanding, and you can fully enjoy the taste of autumn. Toshichika TAMURA: He studied Chinese studies as a child and English studies as a boy. In addition, he trained at Kochi Prefectural Ceramics School. He spent his time as an educator in Kochi and Miyazaki prefectures from 1878 to 1886. 87 species that belonged to Miyazaki Prefecture cultivated during work: Recognized that “Citrus” is excellent, named “Hyuga-Natsumikan（Summer Orange）”. Around 1891, send scions and saplings to Homeland’s father. Instead of Mr. TAMURA, we started growing and cultivating seedlings. In Kochi prefecture, it is often called simply ‘Konatsu Citrus’（It started when it was discovered by chance in a mansion in Miyazaki prefecture in the early 18th century. At that time, it wasn’t eaten with strong acidity, but it seems that it has been widely cultivated since then. The origin of the species is thought to be a mutation of Yuzu, the skin is yellow, and the size is about the same as that of Satsuma mandarin.）The standard Japanese name is “Hyuganatsu Citrus（It is thought to be a mutant of Yuzu found in the garden of Yasutarou Magata in Miyazaki City around 1820 during the Edo period. At the time of discovery, it seems that it was not eaten with strong acidity, but after that, breeding progressed and it became a special product of Miyazaki prefecture, and now it is cultivated in various places.）”. “Mango” has been cultivated in Japan since the Showa era. Shoichi TATE: In 1984, at that time, he instructed farmers to grow as the chief of fruit trees in Japan Agricultural Cooperatives SAITO. I was impressed by the encounter during my visit to Okinawa and brought it to Miyazaki. It wasn’t until the 2000s that domestic production increased. However, it was not easy because pollen is vulnerable to rain. One by one, carefully net and ripen and harvest naturally fallen fruits from the branch. The sweetness and flavor of ‘Ripe Mangoes’ that have taken time and effort are incomparable to imported products. It also has excellent cold resistance and can be cultivated without the need for a greenhouse. Irwin-Variety introduction-Origin: USA, HADEN, Because of its strong peculiar smell, people have different tastes in Japan. A variety that has a strong taste and is popular in Europe and the United States. The pericarp is red, round in shape, and looks like an apple. First called Apple Mango. Lippenss-It is the mother of Irwin and has a higher sugar content than Irwin.It is a variety with few fibers, and the impression is that it is a little small. The color of the pericarp is slightly reddish yellow even when fully ripe. Origin: Hawaii, Rapoza-A variety that is a child of Irwin, and is a little big. The pericarp is red at the top and yellow at the bottom, with white and fine spots throughout. Impression that it is juicy and sweet and has very little fiber. “Irwin” : Cultivated in Florida, USA-Around 1954, to Tainan City, Taiwan. Later, cultivation became popular in Japan as well. The main cultivated area has a warm climate. It turns red like an apple, and the juicy fruits are bright orange. Most of the mangoes cultivated in Japan. Ripeness is required, but this product is almost fully ripe. It is time to eat after the fragrance becomes stronger and you feel the softness in your hands. Therefore, it is better to have some wrinkles on the skin. A citrus fruit found in Miyazaki Prefecture, named “hyuganatsu (species of citrus, Citrus tamurana)” in 1887, it has become a specialty citrus fruit of the prefecture due to its excellent fruit and efficacy. As the name suggests, it is a citrus fruit that is a specialty of Miyazaki prefecture. It seems that it was discovered as chance seedling in Soi, which is adjacent to Jogasaki, Akae Village in the former Miyazaki District (currently Miyazaki City) from 1818 to 1829, which is the end of the Edo period. Production in Miyazaki City (Kiyotake Town / Takaoka Town), Aya Town（Succeeded in revitalizing the town with the slogans of “organic farming town” and “laurel forest city”）, and Nichinan City seems to account for about 80% of the total. Unlike other citrus fruits, it is a variety that can be eaten with albedo, and the taste is less sour than grapefruit, and the light and refreshing taste is impressive. It has a strong taste, less acidity, and an elegant taste. It is unusual to eat the fluffy white part of the pericarp with the flesh. There is no bitterness and you can enjoy a unique texture. Many of the Greenhouse cultivated ones do not contain seeds, but the open-field cultivated ones seem to have seeds. It seems that the pollen of tetraploid Amanatsu（Citrus natsudaidai）is manually pollinated during the pollination period in early spring to denuclearize it. Those with no seeds are distributed as seedless, and those with a few remaining seeds are distributed as small nuclei. Miyazaki Prefecture is a representative production area for higanatsu (species of citrus, Citrus tamurana), and excellent agricultural products that have cleared particularly strict standards have few seeds and are easy to eat. Because the white skin has a sweetness, you can feel the slight sweetness in the refreshing taste, and it is very popular.
Hyuganatsu Citrus, which has recently become known nationwide as an excellent citrus fruit from Miyazaki, seems to be a rare variety that is eaten together with the white part between the skin and the flesh. I’ve heard that producers use less pesticides to produce excellent agricultural products that are easy to eat, sweet without adding sugar, and have few seeds. It seems that juicy fruits with a refreshing aroma and flavor are born because they are particular about the soil that is the foundation of fruit trees.
Recognized as a unique citrus fruit that is rare in the world. Its color, pulp, aroma, and taste all seem unique to other citrus fruits. If you eat it by peeling the skin with your fingers, you won’t be able to feel the unique taste. Also, just like peeling an apple, the trick is to thinly peel only the outer peel and eat it with the fluffy albedo. The structure of a mandarin orange consists of the orange outer skin flavedo, the white inner albedo, the central core of the fruit called the core, and the edible part of each cluster, which is the gourd sac. It is made of a thin skin) and sand (fruit pulp).
About 200 to 250 g, about the size of a larger Wenzhou mandarin orange. The color is bright yellow and the skin is smooth. The shape looks like a smaller Buntan Citrus. Outdoor cultivation has seeds, but greenhouse cultivation has almost no seeds. Outdoor plants are exposed to wind and rain as they grow, so they are prone to small scratches on their skin, but this is well-known as proof that they were grown in a natural environment. In addition, there are many cultivars of greenhouse-grown cultivars with harmonized sweetness, making them easier to eat.
Greenhouse cultivation, complete isolation and gibberellin treatment. The resulting aqueous solution residue is adjusted to pH 3 with 6N-HCI, and after partitioning with ethyl acetate, the ethyl acetate phase is partitioned with a phosphate buffer solution. The rice buffer phase is adjusted to pH 3 with 6N-HC1, and separated with ethyl acetate to separate the ethyl acetate fraction (acidic fraction).
