From 1333 to 1568, it was during the reign of the Muromachi shogunate in Japan. The Muromachi shogunate was nothing more than a confederation of local warlords, so over time, the Muromachi shogunate gradually lost control of the world. At the same time as the old order collapsed, a new wave of powerful people was born. In order to achieve the goal of seizing power, whether it is treachery, deceit, or fierceness, they will do whatever it takes. In this regard, three words can be used to describe the chaos at this time, that is, "lower gram up". However, the one who brought this tradition to the extreme was Hojo Hayayun, known as the forerunner of the Sengoku Daimyo.
Hojo Hayun, formerly known as Ise Shinkuro, was originally a wandering samurai. His origins were also due to his sister marrying Yoshitaka Imakawa, the daimyō of Suruga Domain. Subsequently, he changed his name to Ise Nagashi. With the death of Imagawa Yoshitaka, signs of civil unrest emerged within the Suruga Kingdom. Imagawa Yoshitada's younger brother Oga Fan Man, who held great power and coveted the position of governor of the family, wanted to squeeze out Imakawa Yoshimoto's son, the Imakawa clan kin, although the clan relatives had already received a letter of succession from the shogunate under the mediation of the Ise Naga clan, but in an era when the shoguns were in danger of protecting themselves, such documents were almost equivalent to invalidity. In order to protect themselves, the Ise Naga clan and the Imakawa clan secretly united the old department of Imakawa Yoshinaka, taking advantage of the fact that the deer Fan Man was not prepared, and performed a decapitation tactic in the middle of the night, successfully eliminating the deer Fan Man, and from then on, the clan relatives sat firmly in the position of governor of the family, and the Ise Naga clan also received a piece of land as a reward - Suruga Kingdom Jundong County Kokokuji Castle.
Location of Xingguo Temple City
When the Ise Nagashi clan asked their nephew for this barren land, the Imakawa clan was deeply surprised. Because Xingguosi City and the 12 townships it encompasses are located on the edge of the mountainous area. Moreover, as the junction of the Izu Kingdom, the Sagami Kingdom, and the Suruga Kingdom, this area is either swampy or wetland, and the grain produced cannot be fed by even 250 samurai! In the era of cold weapons, there is basically no future for development. However, if the Kanto god of war, Michikuni Ota, were still alive, he would have immediately reflected is the intention of the Ise Nagashi clan. Kokokuji Castle is located on nefuya at the southern foot of Mt. Aiying, and although the Hakone Mountains to which Mt. Aiying belonged belonged to barren mountains, it was at the time the choke point of Japan's Kanto and Kansai.
Note: The Kanto Plain in Japan is 16,000 square kilometers, and Tokyo is in the middle. The Osaka Plain, which is about 1,700 square kilometers, is also known as the Plain and the Kansai Plain, because the Japanese city of Kyoto was the capital of Japan from 794 to 1868. Osaka is also located in the Kansai Plain.
Illustration of Kanto and Kansai
At that time, Japan was at the end of the Muromachi shogunate, and there were two roads leading from Kanto to Kansai: one was the Ashikagasan Way, and the other was hakone-Ieyōsan Road. In addition, both the Ashikayama Road and the Hakone Mountain Road can only meet at the Fuji River, or at Nekoya at the southern foot of Mt. Aiying, before heading towards Kansai. It can be seen from this that the Xingguo Temple Castle, located near The Eagle Mountain, will not leak in peacetime, but it will certainly become an important fortress in wartime. This year, Ise Nagashi was 57 years old, and Japan was still in turmoil.
Three years later, in 1490, the Ise Nagashi clan quickly built kokokuji Castle on a large scale by encouraging farmers to open up new fields and not collect taxes for three years. Subsequently, the Ise Nagashi clan subdued the wind demon clan, a ninja who lived in seclusion in Kaneshiyama. At that time, Japan was in the autumn of troubles, and in the early years, the shogunate sent to the Kanto region, ashikaga Masatoshi, the new public faction, had been dead for many years because of the problem of the transfer of power and the kanto husband, the Furukawa Gongfang, and then Ashikaga Masato had no choice but to settle in the Izu Kingdom, calling him Horikoshi Gongfang. In 1491, after Ashikaga Masamune passed the position of governor to his second son, Rui Tongzi, before his death, he caused dissatisfaction among the eldest son, Cha Cha Maru, who then attacked and killed Rui Tong and established himself as the governor of the Horigoku Katakata. Mother-killer? This kind of behavior undoubtedly gave Ise Nagashi a good excuse to seize power!
Note: The ashikaga clan, the first shogun of the Muromachi shogunate, sensed the inconvenience of domination in the Kanto region of Japan, sent his four sons, ashikaga Kishi, to the Kanto region to take charge of ten kingdoms, including Kai, Izu, Sagami, Musashi, Amaterasu, Kamiso, Shimosō, Ueno, Shimono, and Tokiwa. Subsequently, the descendants of the Ashikaga clan called themselves "Kanto Gongfang". Later, after the new Gongfu Ashikaga Masatoshi repelled the Kanto old man to the Furukawa area of Shimo-kuni, the two sides formed a tug-of-war. As a result, Ashikaga Masatoshi established a residence in Izu and called it "Horigoku Kokata", and the original husband was also known as "Furukawa Kokata" (Kamakura Kokata).
In 1493, the Ise Naga clan came to Surufu Castle (Shizuoka Prefecture), a relative of his nephews, and borrowed 300 elite soldiers from the Suruga Kingdom, plus 200 men of the Ise Naga clan, to form a special force of 500 men. Subsequently, the Ise Nagashi clan led his troops from Kiyomizu Port across Suruga Bay and quietly approached the Izu Kingdom. At this time, the Kojikō Tea Pill was engaged in an expansion war, and the country was very empty, and then the Tea Tea Pill was easily driven away by the Ise Nagashi clan. In order to win the hearts and minds of the people, the Ise Nagashi clan immediately released the crime of killing his mother and brother in chachamaru and the tyranny of chachamaru in the two years since he ruled the Izu kingdom. Of course, since the Izu Kingdom was taken, it was inevitable to build a castle and settle down (Leek Mountain Castle). For the Ise Naga clan, the three major forces of the Izu Kingdom, Kano Castle, Izu Castle, and Fukane Castle in Takata County, one is from the wild samurai clan, and the other is that the Ise Naga clan relies on tricks to kill the tea tea pills, which is very disgraceful. As a result, under the leadership of the small and medium-sized hao clans in the Izu country, they stirred up the chaos of Izu in a flash.
At this time, a plague saved ise Nagashi. The Ise Nagashi clan took drastic measures, not only treating the villagers free of charge but also providing them with diet and follow-up medicine. This trick was indeed clever, and the people of the Izu country submitted one after another. Kano Castle and Izu Castle saw that the trend had gone, so they returned to Shun. However, Cha Cha Maru's nemesis, Deep Roots City, refused to surrender. The Ise Nagashi clan then mobilized more than 2,000 samurai and captured Fukane Castle after a battle. This battle was the first large-scale battle in the life of The Ise Nagashi clan, and it was also the fiercest battle fought by the Ise Nagashi clan. After the war, in order to kill Ichigo, the Ise Nagashi issued an order to slaughter the city. At this moment, the Izu Guohao clan, who were wandering on the sidelines, finally bowed their heads and surrendered. At this time, only thirty days had passed since The Ise Nagashi clan entered the Izu Kingdom. With the Ise Nagashi clan taking control of the Izu Kingdom, its residence, Tsuyama Castle, was completed. Because of the slaughter of the castle, the Ise Nagashi felt that his sins were heinous, so he immediately ordained at hayun-an, which he had donated, and added a new Dharma name, which was called "Ise Hayun-an Tsung-ri". After the conquest of Izu Domain, the Ise Nagashi clan did not stop, and his eyes began to focus on Odawara Castle in the Kanto Sagami Kingdom.
Sagami Province
The Ise Nagashi knew that the Izu Kingdom was surrounded by water on three sides, and in addition to his ally Suruga Kingdom, the Kanto Sagami Kingdom was the only direction he could break through. However, in order to enter the Sagami Kingdom, it was necessary to take Odawara Castle. However, the general guarding Odawara Castle was the right-hand man of the former Kwantung god of war, Ota Michikuni, the Omori clan. While following Ota Michikuni, the Omori clan witnessed firsthand how the Ise Naga clan used his superb skill to earn the Imakawa clan the status of heir of the Suruga Kingdom. Although the Ise Naga clan often extended an olive branch of peace, the Omori clan knew that this was nothing more than the Trick of The Ise Nagashi's "slow-cooking frog". Therefore, in the end of the Omori clan, the Ise Naga clan did not have a chance to start. There was no way, Ise Nagashi could only wait, like Sima Yi!
The territory of the Hojo clan during the reign of the fifth generation of the Hojo clan
In 1495, the Omori clan, who died that year, left a last word to his son, "Ise Shinkuro is a thief of the country." This thief is dedicated to stealing the country of others, and ru and so on must not be allowed. However, beauty and spirits did not work for Omori Clan Lai, and the newly succeeded lord of Odawara Castle Omori Fujirai was very useful. In September of that year, the Ise Naga clan raised a thousand cattle and attacked Odawara with fire cattle. After dawn, Odawara Castle fell. This year, Ise Nagashi was 63 years old. This year was also the year when the Ise Nagashi clan shook Kanto. A down-and-out samurai who became the head of a country in just 8 years. Does this confirm his heroic declaration that "the incompetence of the Lord will be replaced." Later, it was thanks to the foundation laid by the Ise Naga clan and the wise leadership of the next four generations that the Ise clan became the new hegemon of the Kanto region of Japan. After the death of the Ise clan, his son Ise clan considered that the Ise clan lacked roots in the Kanto region. As a result, the Ise clan falsely claimed to be a branch of the famous Hojo clan of the Genpei period, and adopted the hojo family's family emblem, Hojo Lin. Since then, the Ise clan has been renamed the Hojo clan. As a result, Hojo Hayafu had a name that he had never used before his death--Hojo Hayayun.
