did they mention that the creator goes by a japanese psuedonym? i'd find it quite funny if they didn't even bother to mention that.
They just mentioned that he goes by the name "Satoshi Nakamoto." No more commentary than that.
Jon Waller's voiceover/translation is sufficiently accurate. There's nothing too special or outlandish in the coverage, other than perhaps the emphasis on "no one will take responsibility if you lose all your money." It's overall moderately positive/neutral...but the very fact that it was covered on NHK for such a long segment is extremely positive, because Japanese coverage has been almost nil so far.
