Just two months ago, Japan disclosed a rough SKETCH for its six-generation fighter. Naturally a magazine says we should not take the sketch too seriously. See
Bradley Perrett, Japan Keeps Pilot In Sixth-Gen Concept. Aviation Week, Nov. 15, 2010.

The print edition but not the online version had the sketch.
And everybody knows: Japan may be technologically up to the job, but due to limited market (it can not export), anything (armament, that is) it makes is
uber expensive.
