@kingswagii1607 from navweaps.com According to US Naval Technical Mission to Japan report O-47(N)-2, the Japanese saw the following deficiencies in these mountings in decreasing order of seriousness: The multiple mounts could not be trained and elevated rapidly enough, either by power or manual drive. The gunsights were inadequate against high speed aircraft. The guns had excessive vibration, making them difficult to keep on target. The capacity of the ammunition supply equipment was inadequate, causing interrupted fire and a greatly reduced operating routine. The muzzle blast caused problems for both the guncrew and equipment. A single hand-held weapon would address the speed of train issue, but still be crippled by the others. As for why they continued using it, the bought a license from Hotchkiss and started production in the mid-30s. so they had a lot of them by the time the problems became apparent. By the end of the war they had a few hundred copies of the 40mm Bofors captured from the British, but thousands of 25mm guns and no other real options.

@karlvongazenberg8398 it seems to me that all the Axis light and medium AA suffered from the reload/ammunition capacity issue. They basically had just enough ammunition to get on target using tracer, and then stop to reload. Japanese 25mm, German and Italian 20mm and Italian 37mm, all had this issue. The early German 37mm was single shot, even worse, and they didnt mimic the Bofors feed system until 1944. The 60 round drum on the Oerlikon, continuous clip feed on the Bofors, and massive belts on the 2-pounder pom-pom made a huge difference in effectiveness. Good sights can compensate, depending on the range, but nobody had good enough sights until late in the war.

@bkjeong4302 they also had the 13mm Hotchkiss heavy machinegun, which they were still producing at about 1200/month at the end of 1944. At the start of the war both the US and Japanese had heavy MGs and light autocannon (25 or 28mm), but when the US found they didn't work that well they had alternatives (Oerlikon and Bofors guns). The Japanese received a few 20mm guns from Germany, and produced a few hundred copies of the Bofors captured from the British, but never had an alternative to the many thousands of 13 and 25mm Horchkiss guns they'd invested in so heavily before the war. They were trying to fend off late-war aircraft and airstrikes with early-war AA suites.
