History

Construction of the advanced Hatsuharu-class destroyers was intended to give the Imperial Japanese Navy smaller and more economical destroyers than the previous and destroyers, but with essentially the same weaponry. These conflicting goals proved beyond contemporary destroyer design, and the resulting ships were top-heavy design, with severe stability problems and with inherent structural weaknesses. After the "Tomozuru Incident" of 1934 and "IJN 4th Fleet Incident" in 1935, Hatsuharu underwent extensive modifications on completion to remedy these issues.

Hatsuharu-class destroyers used the same 50 caliber 12.7 cm gun as the Fubuki-class, but all turrets could elevate to 75° to give the main guns a minimal ability to engage aircraft .
