Type: Infantry rifle.


Ariska Model 1897 rifle
First Ariska Model 1897 rifle
When the Japanese Army, like many others, decided to introduce a magazine rifle, it came to the realization that the Mauser system was the best solution. But like some other armed forces, they preferred their own product and had some other ideas about what makes a good rifle. So they took Mauser as a starting point and developed their own version.

The design was the work of today unknown technicians, but the commission, which was set up by the emperor for the development of the new rifle, was headed by Colonel N Ariska. And that’s why the rifle has since been known by its name.

The first repeating rifle Model 30 was completed in 1897 and perfected in 1905. This weapon, designated Meiji 38, was introduced in 1905, which was the 38th year of the reign of the Japanese Emperor Meiji, hence the designation Model 38. The weapon replaced the original Model 1897 and had two or three improvements.

The mechanism is basically like that of Mauser, but with a large mushroom-shaped safety button on the back of the bolt, which led to a revision of the trigger mechanism. In addition, some characteristics of the Mannlicher rifle were adopted, combined with some Japanese developments.

An unusual addition, which is only rarely available in preserved specimens, was a sheet metal cover, which worked together with the bolt and prevented rainwater or dust from entering the mechanism. While this functioned as intended, as with most other such devices of a similar nature, it was threadbare and tended to rattle at the most adverse moments, indicating the position of the wearer of the weapon. So most of these covers were ‘lost in action’ at the first opportunity.

The 6.5 mm caliber was adapted to the smaller stature of the Japanese soldiers, and the 50.25 inch rifle’s length should increase its range in bayonet combat. This makes the rifle quite unwieldy.

The Ariska rifle was also exported to Thailand and used by the troops of various warlords in China. During the First World War Britain purchased 500,000 Ariska rifles for the Royal Navy and training purposes. Russia used 763,000 pieces of the models of 1897 and 1905 for units on the northern front. In Mexico, the rifle was adopted with caliber 7 mm in 1913.

Like the Italians, the Japanese also came to the realization that their older 6.5 mm caliber was not efficient enough and therefore developed a new 7.7 mm cartridge in the 1930s as a replacement. As a logical consequence, a rifle had to be developed which could fire this cartridge. This was no more than a caliber-drilled Model 38 as Type 99. It had some other questionable new features, such as a special visor for shooting on low-level planes, but this affected the weapon’s rate of fire.
However, few of the new rifles reached the hands of the troops and the Japanese were no more successful than the Italians in the change of caliber, which was mainly due to production difficulties.
As a result, the 6.5 mm cartridge with the associated rifle remained the Japanese standard during World War II. The Model 38 became one of Japan’s most famous and well-known infantry weapons.

After the Pacific War was in full swing in 1942, the production standard for the Japanese Ariska rifles and carbines dropped quickly. Each part of the weapon, which was not necessarily needed, fell by the wayside during the production process. This went so far that due to the Allied sea and air blockade, some rifles manufactured at the end of the war had to be built with poor quality wood and metal, making them more dangerous to the shooter than his target. In the end, even single-shot weapons were built with 8 mm pistol cartridges.

Carbine M1938: Allegedly made for cavalrymen and artillerymen, this model was also used by Japanese infantry, who even preferred it to the standard rifle because of it’s about a foot shorter length and a half a pound lighter weight. The mechanism of the weapon was the same as the long rifle. In addition, there was a foldable version for the parachute arm.

Sniper Rifle M97: This was the original Ariska rifle with an extra bipod and a low resolution scope on the left side of the rifle to allow reloading. The locking handle was folded down to prevent the shooter’s hand from contaminating the visor when the bolt was operated.
