While the KI-78 was impressive, it was only used as a high-speed project and only one airframe flew.

The photos posted above weren't of it's capture by U.S. forces, just as these two aren't, either.

However, this is a photo of the KI-78 after being captured by U.S. forces in 1945.

Not the KI-78 but one of the destroyed was reproduced in the post war.
The Koken long-range monoplane.
