As fierce as the typhoons of 1934-35 were for the destroyers Yugiri and Mutsuki and the carrier Ryujo, their lessons helped Japan launch World War II.
After World War I, the Imperial Japanese Navy concentrated on preparing for a possible confrontation with its most likely adversary, the U.S. Navy. Japanese naval leadership faced two major challenges: The first was the numerical superiority of the U.S. battle line, 14 battleships to Japan's 10; the second was the set of restrictions on warship construction imposed by the international naval arms limitations system which, until 1937, froze this ratio in place.
To compensate, the Japanese Navy turned to tactical innovation and superior warship design. During the 1920s, it worked out an attrition strategy using light forces, including destroyers and cruisers, against the U.S. fleet, which was expected to plow westward through the Pacific in the course of a possible war. A key aspect of this strategy was Japanese emphasis on night torpedo attacks from destroyers and cruisers against U.S. capital ships.
