The devs had ruled out all "unhumane" weapons like kamikazes, this triggers serious political issues in Japan, especially given that how popular this game is right now. (and yes, Battlestations:Pacific being able to play as Kamikazes were considered improper in Japan, and would be practically impossible if that was a Japanese game)

The evidences can be found in yet another interview (need time to search), as well as Kitakami's design and quote.

T-that? I'd rather not load any...

This refers to the suicidal torpedo "Kaiten", which she was remodeled to carry, but never used in combat. In the game, it was replaced by Type A Ko-Hyoteki midget submarines, which she wasn't able to carry historically.
