Shoki was used in Burma, China, Philippines, Java, etc. I don'think it were used in New Guinea (maybe in a very small quantity, I don't know). In CBI it was a very important airplane (the best Japanese plane available until the Ki-84 arrived to China. Not Ki-61 in Burma). Very useful against those Spitfires!
The most widely used version was the IIb, hence my question.
