Ranks of the Imperial Japanese Navy

The Ranks of the Imperial Japanese Navy were the rank insignia of the Imperial Japanese Navy, used from its creation in 1868, until its dissolution in 1945 following the Surrender of Japan in World War II. The ranks were inspired by the ranks of the Royal Navy. The officer rank names were used for both the Imperial Japanese Army and Imperial Japanese Navy, the only distinction being the placement of the word Rikugun (army) or Kaigun (navy) before the rank.
