I think you are correct, Capt. Vick.
Saitozaki airfield was located nearby Kyusyu Aircraft and used for test flight before deployment. It was called Brady Air Base of U.S. Air Force till 1970.
Other than a somewhat similar glaszed nose treatment there's nothing in common between the Kyushu Q1W and JU88.
The Q1W was smaller, had less than half the power, over 100 mph slower, and had 1/3rd the bomb load of the Ju88.
