Wow! Thanks for sharing us. :o
What a complicated wing shape.
I understand that Kayaba type 4 was Ku-4.

Following pictures shows Kayaba H.K. type aircraft. It's perhaps Kayaba type 1 aircraft.
H.K. means Hidemasa Kimura, the designer of this aircraft.

If you look at the 3 view diagrams and other pictures of the Katsudori it doesn't look like there is enough room in the aircraft for both the air intake and the cockpit. Does anyone have a drawing of the internal layout?

Cannot really interpret the boxart/artist impression in relation to the pilots position,
but that thing above the engine intake is a lounger for the prone pilot ?
Otherwiese he could only have had a "Münchhausen" like ride on that engine.  ;)

HA,HA.... Thanks Jens!
Next picture from MENG MODEL. I wonder the ground clearance.
Is it launching position?

Certainly, at least, as long, as the Ki-67 wouldn't have used the Katsudori landing gear !  ;)
(the line beneath the side view marks the ground clearance)
I think, it would have been retracted into the bomb bay, just as in the case of the G4M with the
Okha, but not simply dropped, but lowered with a rack to start the engine prior to launch.

The configuration of the Ku-6 tank glider
is not that clear it seems...?

So, any further information on the cockpit position?
 
The Meng model places a turbine blade disk immediately inside the nose inlet.  While being entirely wrong for a ramjet, leaving it off would reveal the unfaired cockpit tub assembly.  I originally though the large hump behind the cockpit was actually part of the cockpit - this, much like the Skoda Kauba SK P.14.01.  But apparently, the pilot's position was not prone and thus the inlet had to have been trunked around the cockpit "tub."
 
Any further details on what that might've looked like?

Yes it is.
But perhaps the wings of No.1 picture and No.5 picture were very hard to have enough wing root strength for bending moment due to lift.
These wing shape need heavy weight large flange and many bolts at the wing root. It took many time to remove the wing from the tank.
And thanks Madoc. ;)

Katsuodori was a ram jet fighter which the Kayaba factory developed independently. The Kayaba factory began to develop the ram jet engine from 1937 and the design of the ram jet engine was completed in 1943. Katsuodori flying wing fighter was designed to have this ram jet engine. The wing of Katsuodori was a swept wing based on the wing of the Ku 2 type glider, and the vertical tail was attached to the both-wings tip. The ram jet engine which was the main power was stored in the fuselage, take the air from the nose of the aircraft, and discharged combustion gas from the tail of the aircraft. The auxiliary power for putting a ram jet engine into operation was the gunpowder rocket attached to the both sides of the fuselage. The gunpowder rocket consisted of a total of four of every two right and left. When Katsuodori departs, first, every one right and left and a total of two gunpowder rockets were lit, and it takes off, and drops these two gunpowder rockets burned out 5 seconds afterward. When the two remaining gunpowder rockets were lit simultaneously and these two gunpowder rockets were burned out 10 seconds afterward, the speed of fighter plane arrived at Mach 0.3 order. At this time, Katsuodori lights a ram jet engine, go abruptly up to an altitude of 10000 meters, and it glides when air battle, and returns to a base. The climbing time up to 10000 meters was short and the battle time in 10000 meters was 30 minutes, Katsuodori was far advantageous compared with Shusui rocket fighter. When Katsuodori was put in practical use, it must have become an epoch-making interceptor. However, although the mechanism was easy, the ram jet engine needed delicate operation for operation, and in order to put in practical use, there were many problems which must be solved. Since Katsuodori did not have the prospect of the budget, it did not realized.
