The Type 99 was introduced at the onset of World War 2 to supplement, and later replace, the rather underpowered Type 38. This new rifle used a much more potent 7.7x58mm Arisaka cartridge, which it shared with Japan's various machineguns. Such a transition was never completed before the nuclear bombings of Hiroshima and Nagasaki ended the war. As far as bolt-action rifles go, the Type 99 (especially the earlier variants) are some of the finest and toughest available; its chrome-lined barrel, robust bolt assembly and detailed finish ensure smooth operation even in extremely hostile terrain. For this reason, despite being obsolete for two decades, the Type 99 is extremely sought after within the Oceanykan weapons market.
