Stephen Trijble came across this video of Japans for developing their own stealthy fighter.

It appears to be similar to the F-22 in configuration, and it looks like they are looking for stealth and supercruise, though the slab sides on the side of the fuselage (at about 0:25) look to my very untrained eye to be an issue, and given that it is much smaller than the F-22, to my eye less than 1/2 the weight, I’m not sure how much it would be able to carry internally.

It also looks like they have a 3-D thrust vectoring system on the the video (2:30)is very similar to that of the X-31 Enhanced Fighter Maneuverability test bed (shown in bottom picture).

It’s a wicked neat video, and the translation, while sometimes clumsy, is sufficient.
