Type 99 Arisaka

Kokura Arsenal · Rifle · Out Of Production · 1939

Also known as: Type 99 Short Rifle, 99 Shiki, Arisaka 99, 7.7 Jap

Overview

The Type 99 Arisaka was the standard bolt-action service rifle of the Imperial Japanese Army from 1939 to 1945. Developed to replace the older 6.5mm Type 38 with the more powerful 7.7x58mm Arisaka cartridge, it featured an aircraft-sighting rear leaf, a folding wire monopod, and a sliding dust cover that traveled with the bolt. Approximately 3.5 million were produced before Japan's surrender, with late-war 'last-ditch' Substitute Standard variants showing dramatically reduced fit and finish.

Notes

Surrendered Type 99 rifles often had the Imperial Chrysanthemum (Kiku) on the receiver ground off as a condition of surrender. Late-war 'last ditch' rifles use crude sights, wooden buttplates, and simplified bolts.

Background

When Japanese soldiers surrendered, occupying Allied forces required them to grind off the 16-petal Imperial Chrysanthemum (Kiku) crest from the receiver, symbolically severing the rifle from the Emperor. Original unground Type 99s remain prized collector items today, while ground specimens vastly outnumber them.
