The vulnerability of Japanese naval codes and ciphers was crucial to the conduct of World War II, and had an important influence on foreign relations between Japan and the west in the years leading up to the war as well. Every Japanese code was eventually broken, and the intelligence gathered made possible such operations as the victorious American ambush of the Japanese Navy at Midway in 1942 (by breaking code JN-25b) and the shooting down of Japanese admiral Isoroku Yamamoto a year later in Operation Vengeance. The Imperial Japanese Navy (IJN) used many codes and ciphers. All of these cryptosystems were known differently by different organizations; the names listed below are those given by Western cryptanalytic operations. (en) La vulnérabilité des codes de la marine japonaise fut cruciale pour la conduite de la Seconde Guerre mondiale et eut également une influence importante sur les relations étrangères entre le Japon et l’Ouest au cours des années qui ont précédé la guerre. Tous les codes japonais furent finalement brisés et les renseignements recueillis rendirent possibles des opérations telles que l’embuscade américaine victorieuse contre la marine japonaise à Midway (JN-25b) et la destruction de l’avion transportant d’Isoroku Yamamoto durant l’opération Vengeance. La marine impériale japonaise (MIJ) utilisait de nombreux systèmes de chiffrage et de codes. Tous ces systèmes de cryptage étaient connus différemment par différentes organisations; les noms énumérés ci-dessous sont ceux donnés par les services de cryptanalyses occidentaux.
