Type 38 rifle

The Type 38 rifle (三八式歩兵銃, sanhachi-shiki hoheijū) is a bolt-action service rifle that was used by the Empire of Japan predominantly during the Second Sino-Japanese War and Second World War. The design was adopted by the Imperial Japanese Army in 1905 (the 38th year of the Meiji period, hence "Type 38"). Due to a perceived lack of power in its 6.5×50mmSR Arisaka cartridge, it was partially replaced during the war with the 7.7×58mm Arisaka Type 99 rifle, but both rifles saw usage until the end of the war.

The Imperial Japanese Army introduced the Type 30 rifle in 1897. However, the weapon had numerous shortcomings, which were highlighted by combat experience in the early stages of the Russo-Japanese War. These included bursting cartridges, a poorly designed lock in which excess gunpowder tended to accumulate, burning the face of the shooter, frequent misfires, jamming, difficulty in cleaning, and cartridge extraction. Major Kijiro Nambu undertook a redesign of the Type 30, which was introduced in 1906. Nambu reduced the number of parts making up the Type 30's bolt from nine to six and at that same time simplified manufacture and disassembly of the bolt without the need for tools. A dust cover was added because of experiences in the Russo-Japanese War that left rifles inoperable from dust. The weapon was produced in several locations:

In 1939, the Type 38 rifle manufactured by these arsenals cost 75.9 yen per unit. By 1940 more than three million Type 38s had been issued to the Imperial Japanese Army. However, a concern that the 6.5×50mmSR Arisaka cartridge did not compare favorably to the ammunition used by the other great powers in the war led to the introduction of a further generation of rifles in 1939, during the Second Sino-Japanese War. Designated the Type 99 rifle, this new rifle used the more powerful 7.7×58mm Arisaka cartridge already in use with the Type 92 heavy machine gun and the Type 97 light machine gun. However, not all units received the new weapon, and the mixture of types with incompatible cartridges led to considerable logistics issues during World War II.[citation needed]

The Type 38 rifle used the 6.5×50mm Arisaka cartridge. This cartridge produces little recoil when fired. However, while on par with the Norwegian and Italian 6.5 mm military cartridges of the time, the 6.5×50mm was not as powerful as several others in use by other nations. The Type 38 at 128 cm (50.4 in) was the longest rifle of the war, due to the emphasis on bayonet training for the Japanese soldier of the era, whose average height was 160 centimeters (5 ft 3 in). The rifle was even longer when the 40 cm (15.75 inches) Type 30 bayonet was fixed. The Type 38 was fairly heavy, at about 4.25 kg.

Post-war inspection of the Type 38 by the U.S. military and the National Rifle Association of America found that the Type 38's receiver was the strongest bolt action of any nation's and capable of handling more powerful cartridges.

Nomenclature note: In the West, Japanese equipment is commonly referred to as "Type XX", rather than "Model XX". In the case of a firearm, "model" is a more accurate interpretation of the SHIKI (式) character, but the word "type" has become well-established by collectors for decades.

In the late 1930s to the early 1940s, an unknown number of Type 38 rifles were converted into short rifles at Nagoya Arsenal, that did all rebuilds of Type 38 and Type 44 rifles and carbines. The barrels were shortened to 635 mm (25.0 in) from the standard 794 mm (31.3 in) barrel and the stock shortened to match the barrel while the handguard retained its original length. The result is a Type 38 which is similar in size to the Arisaka Type 99 short rifle. There is no consistency to serial numbers or arsenal marks as the rifles were converted from existing stock. Although total production is unknown, it is estimated that approximately 100,000 were converted.

Intended for use by cavalry, engineers, and other roles where a full sized rifle would be a hindrance, the Type 38 carbine was introduced into service at the same time as the standard Type 38. Its barrel was 487 millimeters (19.2 in), overall length 966 millimeters (38.0 in), and weight 3.3 kilograms (7.3 lb). The carbine lacked a bayonet and the cost in 1939 was 67.9 yen per unit. It was produced in a number of locations:
