List of Japanese auxiliary cruiser commerce raiders
This is a list of the Japanese Auxiliary Cruiser Commerce Raiders in World War II. The success of the German raiders in World War I was not lost on the Japanese. In 1941, Aikoku Maru and Hokoku Maru, two passenger-cargo vessels built for the Osaka Shipping Line’s South America route, were requisitioned for conversion to Armed Merchant Cruisers (AMC).
