The Katsuriki (勝力?) was a minelayer (later converted to survey ship) of the Imperial Japanese Navy (IJN) serving during World War I and World War II, the only ship of her class. She was the first purpose-built ocean-minelayer in the IJN.


In 1914, World War I broke out. Japan, based on the Anglo-Japanese Alliance, joined in World War I as a member of the Allies. Germany dispatched a lot of warships in the Pacific, however, Japan did not have an ocean-minelayer to prevent them from invading their naval bases. They had only small mineboats which remodeled a tugboat. In 1915, Japan decided to build a minelayer in a hurry. Kampon was not able to have much time for her design, and gave her merchant ship structures. Her building cost was managed to under the Eight-six Fleet program with the Muroto-class colliers, because her building was urgent. She was named Katsuriki Maru (勝力丸?).

Service in World War I and Interwar period

In World War I, she acted in the Japanese shore water. On 1 April 1920, she classified to minelayer and renamed Katsuriki. Later, she handled a guard duty in the South Seas. On 1 July 1935, she removed minelayer facilities and received surveying devices from retired survey ship Manshū (ex-Russian steamship Manchuria). In 1937–1941, she surveyed in the coast in China for Second Sino-Japanese War. Her action results were useful for building the Tsukushi.
