Akechi Mitsuhide ( , March 10, 1528 - July 2, 1582), first called J?bei from his clan and later Koret? Hy?ga no Kami () from his title, was a samurai and general who lived during the Sengoku period of Feudal Japan.
Mitsuhide was born in Tara castle, Mino Province-now Gifu Prefecture Mitsuhide is a descendant of the Toki-Akechi family of the shugo Toki clan. Mitsuhide is rumored to be a childhood friend or cousin of N?hime. It is believed that he was raised to be a general among 10,000 by Sait? D?san and the Toki clan during their governorship of the Mino Province. When D?san's son, Sait? Yoshitatsu, rebelled against his father in 1556, Mitsuhide sided with D?san.
Mitsuhide began serving the "wandering sh?gun" Ashikaga Yoshiaki as one of his guardians under Hosokawa Yusai. Sh?gun Ashikaga ordered Asakura Yoshikage to be his official protector, an offer which Yoshikage declined. Yoshiaki appealed to Mitsuhide, who suggested Oda Nobunaga instead.
In 1564, Nobunaga sent his sister Oichi to be the bride of Azai Nagamasa. This aided him in his 1566 conquest for Mino province, and opened the path to Kyoto. The sh?gun Yoshiaki and Mitsuhide arrived at Kyoto, the capital of Japan, converting Hongoku-ji temple to a temporary palace in November 1568. Nobunaga returned from Kyoto on January 4, 1569. The Miyoshi clan and Saito Tatsuoki defeated the daimyo of Mino, and attacked Ashikaga Yoshiaki at Hongoku-ji, where Mitsuhide successfully defended the sh?gun. Nobunaga asked Mitsuhide to join his troops and Mitsuhide decided to serve both the sh?gun and Nobunaga.
Mitsuhide received Sakamoto and built Sakamoto Castle in 1571 after the successful attack at the Enryaku-ji temple. Although Nobunaga rarely put too much trust in his retainers, he particularly trusted Shibata Katsuie, Hashiba Hideyoshi, and Akechi Mitsuhide, who was the first subordinate to receive a castle from Nobunaga. After Mitsuhide received Sakamoto, he moved to pacify the Tanba region by defeating several clans such as the Hatano clan and Akai Naomasa of Tango. Mitsuhide also received Kameyama castle and Tanba Province (550,000 koku).
In 1579, Nobunaga captured Yakami Castle from Hatano Hideharu by promising Hideharu peace terms; however, Nobunaga betrayed the peace agreement and had Hideharu executed. This reputedly displeased the Hatano family, and a short while later several of Hideharu's retainers murdered Akechi Mitsuhide's mother (or aunt).:230 The failing relationship between Nobunaga and Mitsuhide was further fueled through several public insults which Nobunaga directed at Mitsuhide.
In 1582, Mitsuhide was ordered to march west and assist Hashiba Hideyoshi who was currently fighting the M?ri clan. Ignoring his orders, Mitsuhide assembled an army of 13,000 soldiers and moved against Nobunaga's position at Honn?-ji. On June 21, Mitsuhide was quoted as saying, "The enemy is at Honn?-ji!" His army surrounded the temple and eventually set it on fire. Oda Nobunaga was killed either during the fighting, or by his own hand. Nobunaga's son, Oda Nobutada, fled the scene, but was surrounded at Nij? and killed. Despite not killing Nobunaga personally, Mitsuhide claimed responsibility for his death.
Mitsuhide's betrayal of the Oda shocked the capital, and he was forced to move quickly to secure his position. Mitsuhide looted Azuchi castle to reward his men and maintain their loyalty.
Mitsuhide attempted to make gestures of friendship to a panicked Imperial Court; he also made many attempts to win over the other clans, but to no avail. Hosokawa Fujitaka, to whom he was related through marriage, quickly cut ties with him.
Mitsuhide had counted on Toyotomi Hideyoshi being occupied fighting with the Mori, and unable to respond to Mitsuhide's coup d'état. However, having learned of the assassination of his lord, Hideyoshi quickly signed a peace treaty with the Mori, and alongside Tokugawa Ieyasu rushed to be the first to avenge Nobunaga and take his place.
Hideyoshi force-marched his army to Settsu in four days, and caught Mitsuhide off guard. Mitsuhide had been unable to garner support for his cause, and his army had dwindled down to 10,000 men. Hideyoshi, however, had won over former Oda retainers, including Niwa Nagahide and Takayama Ukon, and had a strength of 20,000 men. The two forces met at the Battle of Yamazaki.
Mitsuhide took up a position south of Sh?ry?ji Castle, securing his right flank by the Yodo river, and his left at the foot of the 270-metre Tennozan. Hideyoshi immediately seized the advantage by securing the heights of Tenn?zan; his vanguard then maneuvered to face the Akechi forces along the Enmy?ji river. Mitsuhide's forces made a failed attempt to force Hideyoshi from Tenn?zan. Hideyoshi's general, Ikeda Nobuteru moved to reinforce Hideyoshi's right flank, which soon crossed Enmy?ji-gawa and turned the Akechi flank. Simultaneously, Hideyoshi's forces marched against the Akechi front; this started a rout, only two hours after the battle had begun.

No one knows the specific reason that Mitsuhide betrayed Nobunaga, though there are several theories:
The Akechi family was able to trace their heritage to the Toki clan and from there to the Minamoto clan. It is noted that Minamoto no Yoritomo brought the destruction of the Taira clan the same way Mitsuhide brought an end to Nobunaga, who traces his ancestry to the Taira clan. The sword of Mitsuhide is of the Tensho style; the Tensho Koshirae was first designed to be a replica of Akechi Mitsuhide's own sword.
