Akechi Mitsuhide, Japanese samurai and warlord (b. 1528)
Akechi Mitsuhide (明智 光秀, March 10, 1528 – July 2, 1582), first called Jūbei from his clan and later Koretō Hyūga no Kami (惟任日向守) from his title, was a Japanese samurai general of the Sengoku period best known as the assassin of Oda Nobunaga.

Mitsuhide was a bodyguard of Ashikaga Yoshiaki and later a successful general under daimyō Nobunaga during his war of political unification in Japan. Mitsuhide rebelled against Nobunaga for unknown reasons in the Honnō-ji Incident in 1582, forcing the unprotected Nobunaga to commit seppuku in Kyoto.

Mitsuhide attempted to establish himself as shōgun, but was pursued by Nobunaga's successor Toyotomi Hideyoshi and defeated at the Battle of Yamazaki. The short reign of Mitsuhide is listed as the inspiration for the yojijukugo set phrase mikkatenka (三日天下, short-lived reign).He is still popular in present culture. A ceremonial activity was held on April 15, 2018 in Kyoto.
