Nenohi (子日, ”New Year Day”) [2] was the second of six Hatsuharu-class destroyers, built for the Imperial Japanese Navy under the Circle One Program (Maru Ichi Keikaku).

[4] These conflicting goals proved beyond contemporary destroyer design, and the resulting ships were top-heavy, with severe stability problems and inherent structural weaknesses.

She was docked at Hanoi during the initial stages of the operation to act as a radio station to coordinate wireless communications during the invasion, and was later based at Haiphong as a guard ship.

[8] On 4 July 1942, Nenohi was torpedoed and sunk by the submarine USS Triton while escorting seaplane tender Kamikawa Maru southeast of Attu, near Agattu Island (52°15′N 173°51′E / 52.250°N 173.850°E / 52.250; 173.850).

She capsized two minutes after being hit and sank in five minutes—188 were killed, including Lieutenant Commander Terauchi; 38 survivors were rescued by the destroyer Inazuma.
