Working to upgrade various "*message*.dat" files, I found how current japanese nickname of Ki 46 (Dinah) couldn't be "Shitei", which doesn't mean nothing in that language and was probably misinterpreted from "Shirei", that means "Commander" (Ki 46 was actually defined as reconnaissance and command aircraft). Playing with Wiki and Google translator, I found out that real japanese nickname was Shinji, which means "investigator"; much suited for a recon plane
Cheers,
