Type 99 rifle Arisaka was a bolt-action rifle of the Arisaka design used by the Imperial Japanese Army during World War II.

To gain the superior hitting power of the larger 7.7mm cartridge, several caliber 6.5mm Type 38 rifles were modified for the new round. Although the tests proved satisfactory, the army decided that the added recoil and larger chambering for the 7.7mm cartridge would require an entirely new rifle for the cartridge.
It utilized a "Cock on Closing" action and an unusual safety mechanism, operated by pressing in the large knurled disk at the rear of the bolt with the palm of the hand and rotating it in a 1/8 clockwise turn, which is often misunderstood by Western shooters who are used to the Mauser's thumb lever safety. It featured a quick-release bolt and antiaircraft sights, as well as a sliding bolt cover and monopod. As a bolt-action rifle, the Type 99 was a very solid weapon, but as with all manually operated rifles used during World War II, they were in most close combat situations outclassed by semi-automatic rifles and submachine guns.

The Type 99 is one of the strongest military bolt rifles ever made,but many late-war ("last ditch") rifles used lower quality parts, and a complete lack of finish, as well as shortcuts taken to ease production. The "last ditch" rifles are usually distinguished by their crudeness; poorly finished stock, wood buttplate, very obvious tooling marks in the metal, rudimentary sights and an unfinished bolt knob and handle. Such late war rifles may be unsafe to fire. Unlike its predecessors, however, a disadvantage of the Type 99 was its increased recoil due to the lighter weight combined with a heavier cartridge.

In some cases, these rifles may actually be training rifles intended for firing blank cartridges only. The training rifles were made of mild steel and were never intended for ball ammunition. It is possible that reports of Type 99 rifles blowing up were simply the results of soldiers testing captured weapons. Unaware that they were using drill rifles, they fired ball ammunition in them with poor results and possible injuries. It is possible that this may have unjustly led to the Arisaka having a reputation (at least for the last ditch rifles) for being of poor construction.

The Type 99 can be fitted with a Type 30 bayonet. The Type 30 bayonet had a very long, slender blade, and was grooved to reduce weight. The early models featured a hooked quillion. These bayonets attached to a lug under the barrel and were further stabilized by a loop that fit around the muzzle. Unmounted, it handled like a machete.
