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.

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. Major Kijiro Nambu undertook a redesign of the Type 30, which was introduced in 1906. 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. However, the weapon had numerous shortcomings, which were highlighted by combat experience in the early stages of the Russo-Japanese War.

The design was adopted by the Imperial Japanese Army in 1905 (the 38th year of the Meiji period, hence "Type 38").
