The Ki 67 was first flow in combat by the Army's 7th and 98th sentais and the Navy's 762nd kokutai in torpedo attack's during the air sea battle off Formosa in October 1944. The Ki 67 also operated in China and aganst the Marianas, and in defence of the Homeland.
The ki 67's of these units operated out of formosa not the Phillipines, they did take part in the sea battles that raged during that conflict howeaver, so as has been stated we simply don't have any other plane to fly in the bomber role for the Japanese. it is not likely that HTC will, or would model the Ki 21's or Ki 49's that did take part in those actions from the Phillipines.
