The pic was taken at the Yokosuka airfield. The one on the bottom left is the same as the one on its left with the 601-07 number on the tail. It's the Yokosuka D4Y Suisei.
Can't find any more info on the faired over canopy, possibly a COD machine? Night fighter D4Ys had the rear glazing faired over with a small rectangular window, behind the big 20mmm obliquely firing gun, but not as extensively as this. From Bob Mikesh's book Broken Wings of the Samurai, The Destruction of the Japanese Air Force (Airlife, 1993) there is the same scene and photos as what's been posted here, with the D4Y's canopy clearly seen. Photographed at Oppama Airfield, Yokosuka, the site was used as a gathering point for aircraft that were to be sent to the USA by the TAIUs. Aircraft were collected from different sites and flown to Oppama for shipping to the USA . This was done so by Japanese pilots under escort by US aircraft during the flights. The mystery D4Y might have already been at Oppama before the TAIU got there. It's tail marking visible in the picture, is ]-DY-42.
It's a Suisei Model 43 (D4Y4) Kamikaze version.
Bomb bay door was removed to load a 800kgs bomb.
Observer seat was left for temporary use.
The faired over canopy was not necessarily in time for the early production.
