I'm thinking these may be fantasy types, perhaps from Sora magazine?
These are web translations [I did some editing and put in my thoughts in red]:
The first is the TC-1 type "White Eagle" high-speed bomber:
・Engine: [Ekihiya] two, 1500 horsepower engines
・Size: Width (span) 17.8m; Length 16.6m
・Max Speed: 720 km/h
・Arms: 20mm cannon ×1 and 13mm heavy machine gun ×3
・Propeller: Four bladed "electric" propeller (Pella [propellor?] direction opposite) [not sure what this means...perhaps the blades rotate counter to each other, like the first prototype of the Nakajima J1N Gekko]
・Feature:
[Shi] . ..the improvement of the main wing performance.. ..the peel... use the promotion type
It is an equivalent extent sacrificing the cruising range, and it strains itself in the high speed.
It equips it with the radiator of the engine in the wing.
Next is:
11 "Sorakaze" high-speed type medium bomber
・Engine: Two, 2000 horsepower engines
・Max Speed: 720 km/h in all equipment [I'm assuming loaded].
・Cruising speed: 580 km/h
・Cruising range: 2500km
・Feature:
All metal construction, land-based aircraft
This machine of each part where the propeller used for the head and the bombing ground attack uses four contra types is extremely excellent in view. [not too sure what this part is getting at...contra-rotating props for each engine? Given all the glazing, the excellent view makes sense.]
"Two [perhaps meaning twin-boom or twin engine?] High-speed high-speed type medium bomber"
・Engine: Star type [not sure if this is referring to the name of the engine or a reference to a radial engine which are known as "star" engines due to their layout ] of four air-cooled, 2000 horsepower engines ×2 [the booms look too thin in the front to house dual radial engines, so, perhaps "Star" is referring to a name of the engine which, more likely, are twin inline engines.]
・Crew: 4
Ceiling: 14500 meters
・Arms: 20mm cannon each in the tail, fired by a remote-control. [likely the nose cannon is manual]
・Bomb Load: 1,200kg (600kg per bombbay in the booms)
・Grove chief of a ward:
Because of the crew arrangement towards the center of gravity, G forces are lessened in dives and turns. All the fuel tanks are in the body, and the main wings are extremely thin.
As for the agglutination device, arrival and departure from [**haha] is also possible of [ni] wheel type [naruwo]. [not sure on this as the translator has some issues]
(* [**haha]: Aircraft carrier)
"Flying Fish"-type medium bomber" (!!)
・Engine: Two air-cooled, 36 cylinder, "star" 2400 horsepower engines. [At this point, I'm convinced that "star" is referring to a radial engine]
・Crew: Four
・Maximum Speed: 645 km/h
・Bomb Load: 1000kg
・Feature: All the gun emplacements are operated via remote-control and aiming is via a "television" [!] type sight and has the machine gun 25mm four gates. [apparently, the four 25mm cannons are remote controlled]
Eight 12mm machine guns are possessed the front of nasser [nacelle?] and all bodies moreover.
The propeller is assumed to be a contra type.
[I don't think the inlets are for jet propulsion or even turbojets...just air inlets]
"TK23 type medium bomber"
Max Speed: 660 km/h
Bomb Load: 1,000kg
Armament: One machine-gun, 20mm cannon, and 13mm machine-gun (fixed) with flexible 20mm cannon and two 7.7mm machine-guns.
The underside of the pilot [crew area?] station is an armor plated.
In firearms, as for fixation, the rear side is fighter-bombers assumed to be movable forward.
The captain is located in the field emplacement on the center, and it is here also the operating device. In lower right *, the operation situation of the back field emplacement and the tail field emplacement is shown. [if I read it right, there is a ventral gun station along with a tail gunner station with the pilot in the center of the aircraft]
Three crew
Another medium bomber (the translator had issues with the kanji)
It is a bomber version of the fictitious machine this time.
I feel the thought of such a design as for these though the bomber of Japan at that time does the speed as soon as possible, and was performed the design that attacks the enemy's territory.
Moreover, this also is a feature the machine gun installed backwards, and is used to assume the thing that it is run after from the back by the enemy plane and the bullet is poured, and to drive away the enemy plane. Especially, it appears or I think that I felt misgivings in the development of the airplane of U.S.-Britain.
Moreover, there is the one that looked like Europe and America at that time, especially the design of the airframe of the United States, too. At that time, even the state-of-the-art one is reported in the photograph, and the airplane of Europe and America seems to have been influenced in no small way.
[the author of this site seems to think this plane is fake (and I'm pretty certain the others are fictitious as well) and that it is a high-speed bomber that relies on speed to penetrate enemy defenses in order to make its bomb run. It only has a rear pointing machine-gun in the tail to fire on pursuers. It seems the author is saying that the design of the Japanese plane resembles U.S. and British aircraft and perhaps the plane may not be Japanese in origin?]
