JN-25 was used by which navy?

Explanation:
JN-25 is the designation used for the Imperial Japanese Navy’s encrypted radio communications during World War II. It was the Japanese Navy’s code, and American cryptanalysts eventually broke it, using the deciphered messages to anticipate Japanese plans and movements, notably contributing to the Allied victory at Midway. The other navies—United States Navy, Royal Navy, and Kriegsmarine—used their own separate codes and were not the source of JN-25.
