Shirataka (白鷹, "White Hawk")[1] was a medium-sized minelayer of the Imperial Japanese Navy, which was in service during the Second Sino-Japanese War and World War II. She was the world's first purpose-built anti-submarine netlayer.[2] Also, unlike any other warship in the Japanese Navy, she had two chrysanthemum crests due to her unusual bow configuration.

Under the fiscal 1923 budget, the Imperial Japanese Navy authorized a new type of minelayer (Project H2) to supplement its aging minelayers, the former cruisers Aso and Tokiwa. The new vessel was designed to carry either 100 Type 5 naval mines, or to function as a netlayer based on design features developed through operational experience to counter German submarines gained in World War I.[3] At first the project plans called for Shirataka to be a 5,000-ton dedicated netlayer, and to be paired with a 3,000-ton-class minelayer (project number H1, later called Itsukushima). However, due to budgetary limitations and in response to the Washington Naval Treaty of 1922, the designs of both vessels were scaled down, and Shirataka was called on to serve as a dual-purpose netlayer/minelayer.

Shirataka was launched by the Tōkyō Ishikawajima Shipyard on 25 January 1929, and was commissioned into service on 9 April 1929.[4]
