After the death of Minamoto no Yoshinaka, the Genpei War entered its final phase, which is closely associated with the name of Minamoto no Yoshitsune. On March 13, 1184, he and his brother Noriyori set out to accomplish what their cousin had failed to do: deliver a final defeat to the Taira.
Itinotani Fortress
Yoshitsune's next target was Itinotani, where the Taira forces had concentrated and built fortifications. Their location was exceptionally convenient for defense. On the border between the provinces of Settsu and Harima, west of present-day Kobe, stood a fortress that was not a castle but a sturdy palisade. The narrow coastal strip of land was protected on one side by steep cliffs forming a natural northern wall, and on the other by the sea, where the Taira fleet was anchored. This place seemed impregnable, especially for a clan closely associated with the sea.
The plan of attack
The Minamoto carefully devised a plan of attack. Noriyori was to move along the coast from the east, while Yoshitsune intended to make a flanking maneuver through the lands of Settsu and approach the fortress from the west. A simultaneous attack from two sides could give them a chance to break through the Taira's defenses before they had time to take the emperor and flee to sea.
Yoshitsune's rapid march
After developing a strategy, Noriyori began his advance along the coast from the east. At the same time, Lord Kuro (one of Yoshitsune's nicknames), together with warriors under the command of Miura Juro Yoshitsura, set out for Mount Ichinotani. His march was lightning fast: the journey from Kyoto to the eastern slope of Mount Mikasa, which usually took two days, took him only one. There, the borders of three provinces converged: Tamba, Settsu, and Harima.
On March 16, when night fell, Yoshitsune was informed that the Taira camp, numbering about three thousand men, was located eight miles to the southwest. Without allowing his men to rest, he immediately decided to attack. By torchlight, his troops rushed forward. The Taira warriors, losing their composure, were defeated and fled.
Preparing for the assault
The next day, March 17, Kuro Onzōshi (as Yoshitsune was called as the direct heir to the clan) divided ten thousand horsemen into two detachments. Tōjiro Sanehira received seven thousand men and was to advance on the western slope of Ichinotani. Yoshitsune himself, with three thousand horsemen, decided to make a flanking maneuver through the pass and strike the Taira from behind from the direction of Tamba.
At the same time, Kumagae Jiro Naozane and Hirayama Musha-dokoro Suesige from Musashi Province were the first to set out on the road to Ichinotani. Competing with each other, they attacked the enemy from the sea and loudly proclaimed that they were ahead of Minamoto's main forces.
The first clashes
They were met by the Taira commanders: Hida Saburo Kagetuna, Etchu Jiro Moritsugu, Kazusa Goro Tadamitsu, and Akushitsu Kagekiyo. Their troops numbered twenty to thirty horsemen, and they threw open the wooden gates and entered the battle. During the battle, Kumagae Kojiro Naoe was wounded and the warrior Suesige was killed.
Soon, Noriyori arrived at the head of troops from Ashikaga, Tichibu, Miura, and Kamakura. The battle turned into a fierce melee, where white and red banners were mixed together.
Panic in the Taira camp
Murakami Motokuni's troops set fire to the huts and temporary houses where the Taira troops were quartered. A strong wind drove the black smoke down, and panic broke out in the enemy ranks. Many rushed to the sea, hoping to escape on ships. Ships stood on the shore, and warriors in armor raced to jump into them. One ship could hold four hundred, five hundred, sometimes even a thousand people, which made it impossible to sail away.
When several ships did manage to leave the shore, they did not get more than three hundred yards away before the three largest of them sank. The lower-ranking soldiers who tried to break through to the ships were killed right on the shore. They were cut down with swords and halberds, but even knowing their fate, they continued to cling to the sides of the ships. Some had their arms cut off, others had their joints broken, and they fell, covered in blood, onto the sand of Itinotani.
Death and captives
Among the first members of the Taira family to die was Taira Tadanori, the hero of the Battle of Uji, who had survived at Kurikara. His nephew, Shigehira, also tried to reach the boats. His horse carried him farther than anyone else, but an arrow pierced his sacrum. Jumping to the ground, he tried to drown himself, but found himself in shallow water. Then he grabbed a dagger, intending to commit harakiri, but one of Minamoto's warriors arrived and took him alive — a rare occurrence at that time.
Outcome of the battle
Yoshitsune's lightning attack ended in the complete defeat of Taira at Ichinotani. More than a thousand warriors were killed, including nine generals. At Akashi Bay, Kagetoki and Iekuri captured Taira no Shigehira, a third-rank captain of the palace guard. The governor of Etzena, Mitomori, fell at the Minato River at the hands of Gensan Toshitsuna.
In total, the troops of Yoshitsune and Noriyori destroyed or captured many noble Taira warriors: the governor of Satsuma, Tadanori; the governor of Wakasa, Tsuneyoshi; the governor of Musashi, Tomoaki; Atsumori, a fifth-rank warrior; and Narimori, the former governor of Etzen, Moritoshi. Governor of Totomi Yoshisada captured former governor of Tajima Tsunemasa, governor of Noto Noritsune, and governor of Bitchu Moromori.

The Battle of Uji 1180
Minamoto no Yorimasa did not need a special pretext for his growing hostility toward the Taira clan to turn into open rebellion. The court also included the discontented Prince Motohito, the second son of the former Emperor Go-Shirakawa. He had already been passed over twice in the selection of the heir to the throne. The second time this happened was in 1180, when the young Antoku was enthroned. Thus, Kiyomori, the head of the Taira clan, became the emperor's grandfather.

The Battle of Shigisan
The conflict between the Soga and Mononobe clans, who were related to the imperial dynasty, arose on religious grounds. The Soga supported Buddhism, which had come from Korea, while the Mononobe remained faithful to Shintoism and fiercely opposed the spread of “foreign teachings.” Tensions reached a peak after the death of Emperor Yomei in 587.

The Mongol invasion of Japan
At the end of the 13th century, Japan faced a danger far more serious than any internal strife. In 1271, the Yuan dynasty, founded by Kublai Khan, grandson of Genghis Khan, established itself in China. His army was truly enormous: tens of thousands of soldiers — Chinese, Koreans, Jurchen, and especially Mongols, who had conquered the territory from Korea to Poland and from the northern taiga to Egypt. Only one country remained unconquered — Japan.

The Genpei War
As early as the 8th century AD, Japanese emperors gradually lost their real power and became symbolic figures, under the complete control of the powerful Fujiwara clan. This clan, by marrying their daughters to emperors, effectively monopolized the government of the country: all key military and administrative positions were held by representatives of the Fujiwara.

The Rebellion of Fujiwara no Hirotsugu
Fujiwara no Hirotsugu was the son of Fujiwara no Umakai, one of the most important court officials of the Nara period. By 740, the Fujiwara clan had held the reins of government for several decades. However, in 735–737, Japan suffered a severe trial: the country was hit by a devastating smallpox epidemic. It coincided with a series of crop failures, and together, disease and famine claimed the lives of about 40% of the population of the Japanese islands. The consequences were particularly tragic for the aristocracy. The mortality rate among the court nobility exceeded that among the common people. All four Fujiwara brothers, who held the most important positions at court — Umakai, Maro, Mutimaro, and Fusasaki — died.

The Battle of Inogahara
By the summer of 1556, Oda Nobunaga no longer appeared to be the eccentric “great fool of Owari.” Four years earlier, in 1552, having just assumed the position of clan leader, he managed to defend his position: first in the Battle of Akatsuka, and then at Kayazu Fort. In 1553, together with his western neighbor and ally Saito Dosan, his father-in-law, Nobunaga successfully repelled an attack by the Imagawa clan on the border fort of Muraki. In 1554, he united his own branch of the family with the Kiyosu line. Step by step, the young military leader strengthened his position.

The two-week-long siege of Inabayama Castle marked the dramatic climax of Oda Nobunaga’s campaign to assert control over Mino Province and decisively crush the Saitō clan.
