The Sixth Day of the Great Demon King

Fifty years on earth is like a dream and a fantasy. There are lives and deaths, and the heroes are sorry.

--Oda Nobunaga

The first name that comes to mind is Oda Nobunaga, a legendary figure of Japan's Sengoku period, who has many nicknames.

As a child, Oda Nobunaga never followed the rules, he did not pay any attention to etiquette and manners, and he was even more dismissive of homework such as reading, and he often wandered around, looking for trouble, going up and down the river, fighting and fighting. Locals, including relatives, frowned when they saw this troublemaker, and even Oda Nobunaga's birth mother, Lady Tsuchida, did not like him much, but liked his brother Oda Nobuyuki. This led to a future flesh-and-blood rivalry after the death of his father, Nobuhide. Because of his restlessness, it was intolerable to the Japanese nobles, who had always paid attention to traditional etiquette. So much so that Oda Nobunaga's father, Oda Nobunaga, was often angered by his stubbornness and lamented the misfortune of the family, and Oda Nobunaga also received his first nickname: "The Great Fool of Owari".

It is worth mentioning that Matsudaira Takechiyo (later Tokugawa Ieyasu) was a teenager who was a hostage to the Oda family, so that he could be with Nobunaga, and the two formed a lifelong friendship and formed a strong Cheongju alliance in the future.

After Nobunaga's death, Nobunaga inherited the family governor because of his relationship with his eldest son, but due to his previous rebellious behavior, he was not supported by some of the elders. To this end, after his master Masahide Committed Suicide, Nobunaga wooed Kasunari Mori, Sasa Narimasa, Hidetaka Kawajiri, and others, and received support from his father-in-law, Michizo Saito. In the end, he won the internal battle with his brother Nobuyuki.

Nobunaga's battle for fame was the Battle of Barrel Andama, which defeated the then invincible Imakawa Yoshimoto, thus beginning his legendary campaign against the unification of Japan.

Imagawa Yoshimoto, who had long since raised an army to Gora, formed the "Kojunshiro Three Kingdoms Alliance" in the 23rd year of astronomy (1554) and the Kai Kingdom (present-day Yamanashi Prefecture) to guard Takeda Harunobu (Takeda Shingen), and the lord of Odawara Castle in Sagami Kingdom (about present-day Kanagawa Prefecture) Hojo Clan Yasushi formed the "Kojunshiro Three Kingdoms Alliance", cutting off the worries of the northern and eastern sides of the kingdom, and began to actively plan a westward march. In the third year of The Eternal Road (1560), after Oda Nobunaga had initially pacified the Owari Kingdom, the Tokaido daimyō Imakawa Yoshimoto (いまがわよしもと) personally led an army into the territory of the Owari Kingdom, and imagawa Yoshimoto mobilized the Imakawa family to sweep the territory of the country. At that time, the Imakawa family's territory of Suruga, Ene, and Mikawa, the height of the three kingdoms was around 700,000 stones, and Imagawa Yoshimoto made a full mobilization and gathered 20,000 to 25,000 troops. Pioneer General Ii Naomori marched west along the Tokaido. On May 19 of the same year, Oda Nobunaga led 4,000 troops out of the army.

In the case of the disparity in strength between the two sides and the difference in the experience of the commander in battle, it suddenly rained heavily in the barrel narrow area, and in this regard, Nobunaga showed his essence as an excellent military expert, accurately grasped the fighter, and organized the Oda Army to sneak into the Imakawa Army in the barrel narrow space. The result of this raid was the death of Imagawa Yoshimoto and the defeat of the Imagawa army. After the war, the Imakawa clan, which had dominated Tokaido, declined, while the victorious Oda Nobunaga rapidly expanded its power in Central Japan and, laying the foundation for his future power over the japanese central government.

After this, Nobunaga began his nearly three-decade career of conquest, working to unify Japan and establish a perfect feudal system. He completed the victories of pacifying the Mino region, supporting Thera Yoshiaki Kamilor, destroying the Takeda family, and breaking through the Nobunaga Siege Network three times.

In the process of pacifying Japan, Nobunaga made political, economic, and military changes to the course of Japan's history. Politically, Nobunaga almost became the first daimyō in Japan to accept the emperor's throne, and if this happened, the lineage of the Japanese emperor would cease to exist. Economically, during his reign, Oda Nobunaga removed unnecessary checkpoints (checkpoints for collecting toll tariffs) on the border, used land inspections to establish territorial domination, and separated peasants from military forces to establish a standing army. The establishment of Le City encourages business. Actively encourage free trade and reward technological innovation. Oda Nobunaga also introduced a new daimyo system to improve the local system in various places. Oda Nobunaga also traded with the Southern Barbarians (historically known as the Southern Barbarian Trade), which not only brought economic benefits to Oda Nobunaga, but also advanced practical sciences in the West, such as mathematics, geography, medicine, astronomy, shipbuilding, etc., were also introduced to Japan, which also opened the eyes of the Japanese. Militarily, Nobunaga for the first time put forward advanced military ideas such as the three-stage strike, the separation of soldiers and peasants, and the land inspection system.

Unfortunately, Nobunaga finally changed honnoji and was assassinated by his confidant General Mitsuhide, thus ending his legendary life and leaving behind various legends because the rebels did not obtain his body.

It is said that Nobunaga was in the fire of Honnō-ji Temple, singing and dancing, singing: Fifty years on earth, like a dream and a fantasy. There are lives and deaths, and there are regrets about the heroes......... Finally walk into the fire.

The last thing that has to be said is that Hideyoshi Toyonari is the successor to Nobunaga's mantle, and judging from Hideyoshi's first invasion of Korea in Japanese history, it is very likely that once Nobunaga completed the unification of Japan, it was very likely that he would also invade Korea. All this stems from the constraints of Japan's national, regional, and national conditions.

You have to understand your opponent, including his history, culture, economy, religion, and popular feelings, in order to deal with what may happen in the future.
