Imperial Japanese Army uniforms and ranks during World War II (US Army poster)

The Ranks of the Imperial Japanese Army were the rank insignia of the Imperial Japanese Army, used from its creation in 1868, until its dissolution in 1945 following the Surrender of Japan in World War II.

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. Thus, for example, a captain in the navy shared the same rank designation as that of a colonel in the army: Taisa (colonel), so the rank of Rikugun Taisa denoted an army colonel, while the rank of Kaigun daisa denoted a naval captain.
