The J2M Raiden "Jack" was an interceptor. Good climb rate, decent firepower, good dive capability, not so hot on manuverability or speed (speed is a common problem with Japanese aircraft).
The Ki-46 "Dinah" was a photo-recon aircraft. For the first year or so it was essentially uninterceptable with it's top speed of 386mph and allowed the Japanese to watch everything the Allies did within it's range. It had no armor or selfsealing tanks though. Later they turned it into a so so nightfighter with upward firing guns, but they stepped the cockpit when they did and ruined it's clean looks.
