Imperial Japanese Army Uniforms

From Wikipedia, the free encyclopedia

Imperial Japanese Army Uniforms tended to reflect the uniforms of those countries who were the principal advisors to the Imperial Japanese Army at the that time. The initial uniform colour was dark blue and resembled that of the Union Army of the American Civil War. And as that uniform was based on the French style of the period it was easy to upgrade the uniform and keep the same basic style.

Resembling the Imperial German Army dunkleblau uniform, the dark blue single-breasted tunic had a low standing collar and no pockets. it was worn with matching straight trousers and a kepi (red for Imperial Guard) on which was worn a brass five point star. After the Franco-Prussian War the kepi was replaced with a flat topped peaked cap and the tunic collar became higher. Pockets were added to officers' tunics late in its issue. This last was the uniform worn in the Russo-Japanese War. Tunics were piped in yellow for line troops or red for the Imperial Guard, and trouser seams had a wide yellow or red stripe. Senior officers could wear a double-breasted version of the tunic. Cavalry units wore a short attila jacket with transverse braiding. A lightweight white cotton version was used for fatigue duties and tropical wear.

This was basically a khaki cotton version of the 1886 uniform with a shorter jacket.

[edit] 1911

The 1911 uniform replaced the blue uniform. It was basically a yellowish-khaki (called mustard) colored version of the blue uniform. The cap had a red band, the tunic collar had swallow tailed red patches and the shoulders had red passants to indicate rank. The uniform was produced in wool for winter and cotton for summer wear.

[edit] M90

The Showa Type 5, also called the M90 or 2590 or 1930 uniform was basically the 1911 uniform but introduced internal breast pockets with scalloped pocket flaps on the tunic for all ranks. Also the straight trousers were later replaced with pantaloons which were worn with woolen spiral wound puttees and tapes.

[edit] Type 98

The M98 (1938) was a further modification of the M90 uniform. The single breasted tunic had a stand and fall collar, five buttons which ran down the front and two, or more usually, four internal pockets with scalloped flaps (depending) on manufacturer. Long trousers or pantaloons were worn as standard along with the puttees and tapes. All except mounted troops(who wore breeches and high leather boots) wore this uniform with horsehide, pigskin or leather ankle-boots. The boots had either a hobnailed hard leather sole with metal heel J-cleat or a rubber sole with rubber cleats. When off duty, soldiers could wear tabis. A collarless wool or cotton white, grey or light green under shirt was worn under the tunic. This had one or two patch breast pockets with buttoned flaps, most had only a single pocket on the left breast. A khaki cotton shirt with stand and fall collar and two breast pockets could be worn in warm climates, with or without the tunic. The flat-topped peaked cap was replaced by a cloth field cap with a short leather (or more usually) cloth peak.

[edit] Type 3

The Type 3 Officers Uniform, was introduced in 1943 and was similar to the Type 98 but was made of cheaper materials. It also reintroduced cuff insignias for officers. It was produced in various shades of green.

Officers were not usually issued uniforms so they had to procure their own, thus there was a wide variety in the details, colour and texture of their uniforms, with uniform colours ranging from tan to dark green. Collars were taller and stiffer and materials were of a higher quality. Senior officers could procure and wear a double-breasted version of the blue and M90 uniforms. All ranks wore a single breasted version of the M98. Officers could wear straight trousers with their M98 uniforms as a walking out uniform and later they could also wear the tunic with the collar open over a white or grey green shirt.

[edit] Helmets

  • Adrian helmet - As with many countries, the IJA adopted and produced the French Adrian helmet.
  • Type 92 - The Adrian helmet was later replaced by a Japanese designed helmet called the Type 92 (1932). It was officially called tetsubo or steel cap or tetsukabuto or steel helmet by troops. It was made in the shape of a dome with a short protruding rim all the way around it (the paratroop version only had a short brim in the front). This helmet was made of inferior chrome molybdenum steel with many proving to be very fragile, being easily pierced by gunfire. A star was soldered to the front and the helmet and star were painted mustard khaki. They were sometimes whitewashed in the winter. A tan, khaki or olive-green two layer, fiber reinforced linen cover was available with a yellow star sewn on the front. It was secured by an elaborate set of straps descended from those of the Kabuto or samurai helmet. It was also able to be worn over a reversed field cap. Camouflage nets were widely worn over the helmet especially in the Southern theatre and pacific island campaign.
  • Tropical helmet -
    • Type 90 - was like the cork helmet issued by the European colonial powers. It had a metal ventilator at the top, a couple of ventilation eyelets on either side and a brown leather chinstrap. It was mostly worn by officers.
    • Type 92 - This was a cork version of the Type 92 steel helmet. It was covered with six segments of cloth, and several versions were available. It was issued to all ranks. Officers usually wore a white cover on theirs.

The IJA issued single-breasted over coats, capes and raincoats with hoods in olive drab.

  • Senninbari were a red-sash 1,000 stich belt worn around the waist of their uniforms. The were supposed to bring good luck, confer courage, and make the wearer immune from bullets.
  • Fatigues - White cotton fatigues were initially issued as a tropical uniform but then when a light-khaki(tan) was adopted as a hot weather uniform colour, the fatigues were worn over the standard to keep it clean while doing dirty-work. Later an olive green version of the white fatigues was issued.
  • Tropical - The tropical cotton uniform, designed similar to the M98, were initially available in tan or light khaki, but were superseded later in the war by versions in medium to dark green. They had open collars, buttoned side vent flaps below the armpits, pleated patch or internal pockets with flaps. Trousers could be full-length, 3/4 length, or a loose fitting breeches style pantaloon. The usual uniform worn in the Pacific islands was knee length shorts worn with a lightweight cotton shirt, which had three front buttons , 3/4 length sleeves and patch breast pockets with flaps. Officers wore a, short or long sleeved, lightweight white(or off-white) tropical shirt with the green trousers. When they wore the green tropical tunic they wore the shirt collar outside and over the tunic collar.
