Michiaki KOGA (February 20, 1780 - January 9, 1856) was a kugyo (court noble) who lived during the latter half of the Edo period. He served the two emperors, Emperor Kokaku (the 119th) and Emperor Ninko (the 120th), and was appointed to Naidaijin (minister of the Interior) at the rank of Juichii (Junior First Rank). His father was Michikore NAKANOIN. Who was his mother is unknown. His foster father was Nobumichi KOGA, Naidaijin. A daughter of Harutoshi HOSOKAWA, the lord of the Kumamoto Domain, was his wife.
