As stated earlier, this is a concept jet converted by the Japanese late in 1945 to a jet plane. The propeller version did fly and was rejected as there was no need for a reconnaissance aircraft. So it was decided to convert the design to a jet bomber. The version being built here is merely an addition of a jet engine under each wing with added fuel tanks in the fuselage where the original internal combustion engines resided ( yes it was twin engined prop plane ).
In my technical opinion, this plane would have been a "dog". Big rotund fuselage with two small jet engines and nothing else is like converting a horse drawn carriage into a food delivery truck. It just can't be done.
There was another proposal of installing the two engines at the wing roots. While that would have been a better concept in drag reduction, the inlet technology and long air ducts for the axial flow engines was lacking in Japan at that time.
This project was just doomed to failure and there were better technical solutions for a jet bomber even then. But it makes for a good topic of experimental planes and most likely would have flown if it had another year for development.
All speculation, but fun discussion.
