The navy pronounced it as Dai, while the army pronounced it as Tai. There was a minor difference in pronunciation of character 大 for Navy Lieutenant and Navy Captain. The navy would prefix the common rank names with "navy" ( Japanese: 海軍, romanized: Kaigun), while the army would prefix them with "army" ( Japanese: 陸軍, romanized: Rikugun). Commissioned officer ranks Ranks Īll commissioned officer rank names were the same as their army counterparts. 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. 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. The ranks were inspired by the ranks of the Royal 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.
