Well if their were a plane for the Japanese to consider adding for the ground attack role I think this would be the one. the Ki-102 has some very nice Qualities...
Ki-102b: max spead 360mph @ 19,685ft.,climb to 16,405ft in 6min 54sec.,wing loading 44lb/sq ft, power loading 5.4lb per hp.
215 of the Ki-102b were produced and saw service,namely around Okinawa and the main Is's of Japan.
My main source for this info and some of the scans bellow is: Japanese Aircraft of the Pacific War by Rene J Francillon.
