Did the Imperial Japanese Navy itself use prefixes such as HIJMS?
Short answerHIJMS is identified as an English-language historians' convention rather than an authentic Japanese naval prefix. Other proposed forms would need checking before giving a firm answer.
NotesHIJMS is identified as an English-language convention associated with British and American historians. Such writing conventions need to be distinguished from the Imperial Japanese Navy's own usage. Other suggested forms remain uncertain because their spelling and origin would need to be checked against notes.
