OK--I don't speak Japanese nor understand it. I can't distinguish which of the kaigun ranks is higher. I'm sure Japanese-speaking players who don't understand English also cannot distinguish between Lieutenant and Commander, etc. Suggestion: why not add stripes to the Japanese or English rank-names, such as one stripe for Ensign, 2 stripes for Lieut Jr grade, 4 stripes for Captain, etc., and for their Japanese equivalents as well? This way, it does not matter what "kaigun" or "commander" means--they have their equivalent stripes for everybody to understand.
