Brian,
Strangely enough under 227 (Scale of Enemy Air Effort) it says the Japanese dive bombers were somehow identified as "Junkers 87N - Japanese Version".
See

But didn't Japan receive only two Stukas for testing?
On the other hand this website refers to the "Nate" in the role as dive bomber in Malaya:
