How many times did Japan have?

Ancient times: 1. Rope pattern pottery was used in the rope pattern era (BC 10000 to the 3rd century BC). About 1 10,000 years ago, climate warming and rising sea level caused Japan to separate from the mainland and become an archipelago. People domesticated dogs to catch deer and wild boar, and at the same time invented bows and arrows, which increased the capture of prey. In addition to fishing, people also collect horse chestnut seeds, acorns, walnuts and plant bulbs. People try to get enough food so that they have free time to grind stone tools and burn pottery. Moreover, the range of food has been expanded by starting to eat cooked food. In this way, human beings can settle down in one place for a long time and build vertical caves to live in. The vertical cave is centered on the square, and several families live together, and shells and food scraps are discarded around it to form a shell pile. But this kind of food can't be preserved for a long time, and it is difficult to accumulate the surplus products in someone's hand. In the primitive society where there was no class opposition, fashion did not find any sites and remains reflecting the wealth and power of specific groups. At that time, under the condition of low productivity, the natural resources were limited, so people made strict rules to protect nature within the group. At the same time, witchcraft prevailed, stone sticks and clay dolls appeared, and people had the habit of pulling teeth. People also pray for the abundance of nature. By the end of this era, especially in western Japan, there was a trend of trying to break through the hunting, fishing and gathering economy. Recently, a paddy field site planted with late-rope rice was discovered in Banfu site in Fukuoka Prefecture. 2. Yayoi period (300 BC to 300 AD) is the period when Yayoi pottery was used. According to the form of pottery, it can be divided into three stages: the first, the middle and the last stage. In the early stage, it expanded from Kyushu to Gyeonggi area (East Japan was still at the end of the rope pattern era) and spread to the northeast in the middle stage. The early flat-edged stone axe in Kitakyushu is similar to the mainland culture in terms of ground stone tools, bronzes and stone tombs. Yayoi culture has advanced farming techniques from the beginning, which is generally considered to be influenced by Korean immigrants. After the middle period, irrigation technology has been improved and agricultural production has gradually stabilized. In the later period, iron farm tools became popular and stone tools basically disappeared. Bronze ritual vessels, such as bronze priests, bronze swords, bronze spears and bronze daggers, are developed, and social division of labor such as ironmaking and salt making has emerged. Through trade and war, a unified political regional group was formed. At this time, Hokkaido can't grow rice, and it is still in the stage of rope culture. 3. The ancient grave era (300-600 AD) prevailed in the era of building ancient graves. Ancient tombs, large and small, centered on Nara Prefecture, are scattered in a vast area from Fukushima Prefecture in the north to Kumamoto Prefecture and Oita Prefecture in the south. In the 5th century, it expanded from Miyagi Prefecture to Kagoshima Prefecture. Ancient tombs only buried tribal leaders and were built by tribal members. In the 5th century, the primitive ownership began to disintegrate, the extended family developed into production units and movable property ownership units, and conflicts of interest occurred within the primitive tribes. Since the middle of the fifth century, the civil war between powerful tribes in Guinea has intensified. Some powerful tribes are related to the mockingbird tomb and the ancient city tomb where the five kings of Japan appeared. In the sixth century, the emerging forces of the system of succession to the emperor unified the tribes in the east of the capital and established the status of the king. Kitakyushu forces, led by MICHELLE Iwai's construction, had hoped to gain a similar status and resist, but this resistance had been defeated before obtaining this status. During the civil war, local leaders granted tribal members the right to build small ancient graves to enhance their combat effectiveness. Therefore, in the second half of the 5th century, the ancient grave, which used to be only the head tomb, evolved into a small ancient grave (cluster grave). This trend further developed in the 6th century. More than100000 ancient tombs have been built all over Japan. The main part of the ancient tomb also adopted a horizontal cave stone chamber. Several generations of family members are buried in the stone chamber, with weapons as the center. After death, there are necessities of life, such as hui utensils and earthenware utensils. However, the appearance of a large number of small ancient tombs has gradually weakened the nature of ancient tombs as rulers' buildings. Therefore, from the end of the 6th century to the beginning of the 7th century, Japanese monarchs tried their best to build monasteries in Guinea, and at the same time restricted the construction of small ancient tombs, while kings and powerful nobles were buried in large square tombs modeled after the mausoleum of Emperor China. In this way, the era of ancient graves is coming to an end, and the so-called "thin burial order" of Dahua further encourages this tendency, leaving only the ancient graves of middle-class nobles in Gaosong, which are small but gorgeous. The ancient tombs in Guandong and Northeast China ended later than in western Japan, and the round tombs were still under construction until the first half of the seventh century. 4. The Asuka period (600-700 AD) and the Asuka period refer to the court period of torii (now Asuka Village) in Nara County. At this time, Buddhism came, the Soviet Union of imperial Buddhism and my traditional Shinto hegemony. Sue and I strengthened the blood relationship of the imperial court and expanded our power. In 587, ministry of materials and equipment's housekeeper was killed, and Sue and I arranged it in the imperial court, but we put in the power we didn't have. In 592, Sue and I acceded to the throne with a woman who was related by marriage. She nominated Shoto Kutaishi (Prince of Stairs Gate) as the political regent. Shoto Kutaishi decided to take the first place in the "Article 17 Constitution on the 12th Floor", which created the foundation of bureaucracy in China. At the same time, envoys and students were sent to Sui. The Emperor of Sui Dynasty was able to pass on the credentials as Emperor Yang at this time, and he was angry at the lack of humility in sending the credentials from Japan at this time. During the life of the ancient emperor, my power was suppressed and the world was stable. If she died in 628, she was promoted around the successor Su I who went into the deer to kill her brother's son Wang, and attempted to destroy Su I with her brother Prince (the Emperor of Heaven) and (Sickle Foot) as the center accomplices. According to the great innovation of the emperor's era, Su I was destroyed. Because the friendly country Baekje was destroyed in 660, in order to revive Baekje, 20,000 troops were sent to Korea, and there was a war with the troops of the Tang Dynasty and Xinlingluo in Baicun Bay. Japan, which lost this, made a defensive strategy of letting Shuicheng for the defense of Tai Zaifu. In 670, the year of Gengma was registered. This is the original Japanese account, and now I have another one. If Emperor Tianzhi died in 672, his son Hong Wen ascended the throne. However, as the younger brother of Emperor Tianzhi, Prince Hairen will become Emperor Tianwu if he defeats Hong Wen in Gifu County because of Ren Shen's rebellion. Emperor Wu of Heaven defined his identity with eight-color surnames, and defined his identity on this basis. At this time, Japan forged the so-called independent currency with abundant capital, but it lacked economic concept and did not expand it. The formulation of Dabao Law in 70 1 year (Dabao Year) is determined by the official functions of Japan. Moreover, in 7 10, according to the imperial palace of the Yuan and Ming Dynasties, it was moved to the flat ground, and the Asuka period of leveling the city scene ended. 5. Nara (Heichengjing) was the capital of Nara era (AD 7 10-784). From 7 10 (the third year of copper), Pingcheng well was its capital, and it was moved to Changgangjing in 784 (the third year of extension) for 74 years. It is the heyday of the legal society, which is manifested in the political and economic system, class relations, culture and foreign relations. At this time, political struggles within the nobility continued to occur. After the change of Prince Nagaya, Fujiwara's four clean-ups, the orange brothers fought for power with the monk Yun Xuan, Fujiwara's Hirohito Rebellion, and Fujiwara Nakama rejected the royal family as the first non-royal Zheng Tai minister. Buddhist Taoist mirrors used filial piety to restore the emperor, punish Fujiwara Nakama and promote the French king, in an attempt to covet the throne by abdicating, weakening the absolute authority of the emperor's dictatorship. During the reign of Ren Guang and Emperor Kanmu, the imperial court tried to rectify the chaotic political situation, reduce financial expenditure, reform the military system, expand its territory to the northeast, seek plastic surgery and re-strengthen the legal system. 6. The historical era of Heian Period (794- 1 185), with Heian Jing (Kyoto) as its capital, began in 794 (13th year of Yan Li) and finally 1 185 (the first year of Wen Zhi) established the Kamakura shogunate, which lasted for 40 years. Divided into three periods. The early period (794-967) was a period when laws and regulations were relaxed but continued to be used. The middle period (968- 1068) is the establishment and heyday of social politics. The later period (1069- 1 185) was the peaceful regime of the Yuan government. Medieval: 1. Kamakura period (A.D. 1 185 to A.D. 1333), when Wu Jia regime took Kamakura as the national political center. It started in 1 185 (the first year of Wen Zhi) and ended in 1333 (the second year of Zhengqing and the third year of Justin), lasting 149 years. There were other theories in the early days: 1 180, 1 183, 1 192 (Yuan Lailai was appointed as a general of foreign conquest). After the death of Yuanlaichao, the regime of the shogunate began to be controlled by his wife Masako Kitajima and his father Kosuke Kitajima, who used the position of executive power to overhead the power of the generals. Even after the death of the third generation of generals, he welcomed the noble Fujiwara and even the prince from Kyoto to become generals. Yuan Shizu Kublai Khan invaded Japan twice during the reign of North Island. In the later period, the rule of the shogunate could not be maintained. Finally, Daigo dispatched troops to Weiqi, and was defeated by the general and Ueno imperial clan Ashikaga, and perished. 2. During the Northern and Southern Dynasties (1334 ~ 1392), after Daigo, the Weiqi player, eliminated the Kamakura shogunate, he resumed the imperial government for the first time and implemented the New Deal, which was called the Jianwu New Deal in history. Because the New Deal did not meet the requirements of the samurai, it only reused the nobles in Kyoto, which attracted the dissatisfaction of the samurai. Among them, the first step to respect the history of general is even more dissatisfied. Although he was honored by the emperor's name, he still wanted to open a government. As a result, Ashikaga respected the teacher and forced Go Daigo to abdicate. The new emperor Guangming made him a general to conquer foreign countries. It's from the northern dynasty. After Daigo abdicated, the three artifacts symbolized by the Emperor retreated to Yamato Yoshino (now Nara Prefecture) for the use of the Southern Dynasties. At this point, the Northern and Southern Dynasties finally formed, and the history books also called "two emperors in Nanjing in one day". After many attacks and defenses, the power of the Southern Dynasties declined. Finally, the Emperor of the Southern Dynasties handed over three artifacts to the Emperor of the Northern Dynasties, ending the era of the Southern and Northern Dynasties. 3. In the Muromachi era (A.D. 1392- A.D. 1573), Ashikaga was originally a noble family in Ueno, and what's more, the Kamakura shogunate was a member of the same clan. Ashikazu opened a shogunate in Muromachi, Kyoto, as the Muromachi shogunate. The unification of the Northern and Southern Dynasties was carried out by the third generation general ashikaga yoshimitsu, who attempted to usurp the throne after reunification. But after his death, the fourth generation general Ashikaga Yoshimochi stopped it. When Ashikaga Yoshimasa, the eighth generation general, was in power, Ren Ying rebellion broke out because of the issue of inheritance, and the authority of the shogunate went from bad to worse. The13rd generation general Ashikaga Yi Hui was killed, and his younger brother Ashikaga Yoshiaki was founded by Oda Xintai. Later, due to opposition to Xintai's exile, the shogunate perished and officially entered the Antu Taoshan era. Modern: 1. Antu Taoshan period (1568 to 1600) 2. Edo period (1603 to 1868) Modern times: Meiji: (1868) Taisho: (A.D.191to A.D.1928). Showa: (A.D. 1926 to A.D.1989); Heisei: (A.D. 1989 to present)
