Whoops! s7rikeback will most likely be horrified that his "Support" folder with Nihon Kaigun is empty... So the order of assembly is
1. FotRSU
2. Nippon Maru
3. Nihon Kaigun
4. Roster for Nippon_Maru
#4 is in the MODS folder inside of the Nihon Kaigun mod folders. The idea being that if you are not using Nippon Maru, and only Nihon Kaigun on top of FotRSU, you would then activate the "Roster for FotRSU" after Nihon Kaigun. In other words, the Names.cfg file is NOT installed with the activation of Nihon Kaigun, and the player does have to activate #4 above, in order to have the extra ships identified in the game. Nippon Maru does add a Names.cfg for its set of ships. The one in the "Roster for Nippon_Maru" modlet is for FotRSU, Nippon Maru and Nihon Kaigun combined. We're glad you guys questioned this!
