The Sumitomo NTK-62 (62式7.62mm機関銃 Rokuni-shiki Nana-ten-rokuni-miri Kikanjū?) is the standard issue GPMG of the Japan Self-Defense Forces, known as the Type 62 GPMG. Though the Sumitomo Heavy Industries' M249 has largely replaced it in the JGSDF,[6][7] the weapon still plays a support role as it is still used as a co-axial weapon in various armored vehicles, including tanks and APCs, as well as being a medium support machine gun.

Like all modern Japanese-made firearms, it was never exported.[3]


After years of using the Browning M1919A4 as its standard GPMG during the early days of founding the Japan Self-Defense Forces, Sumitomo Heavy Industries had manufactured the NTK-62 GPMG, designed at Nittoku Metal Industry (NTK) by Masaya Kawamura's team. The GPMG was made to meet the requirements of the Japanese Defense Agency.[1] The designation "62" was present due to the fact that first batches of the NTK-62 were made in 1962 after development started in 1954.[2] It was specifically adopted on February 15, 1962, effectively replacing the M1919 Browning machine gun in J.G.S.D.F service.[1]


The Sumitomo NTK-62 is a gas operated machine gun chambered in the 7.62×51mm NATO cartridge, belt fed with the use of M13 disintegrating links.[3] It has an unusual feed tray as the pivoting lever is above the bolt in the receiver rather than in the feed tray cover found on most machine guns.[8]


Type 74

The Type 74 (74式車載7.62mm機関銃 Nanayon-shiki Shasai Nana-ten-rokuni-miri Kikanjū?) is a fixed mount variant for AFV use, including the Type 74, Type 90 and Type 10 MBTs, Mitsubishi Type 89 IFV and the Komatsu Type 87 Reconnaissance Vehicle.[9]

It weighs 20.4 kg (45.0 lb), unlike the Type 62 which weighs 10.15 kg (22.4 lb).[10]
