I've known him since the time of the events in his book, and can confirm. He was (and still is) an insufferable jerk. Not only does he self aggrandize himself in his book and web site, he pointlessly denigrates and takes down and insults the intelligence of his own colleagues in order to make himself look better (but the net effect was the opposite that he intended). And his book was a work of fiction. Nobody in their right mind would still want to work with him, especially after what happened with his LED company. I know somebody who made the mistake of working with him, and the costly lawsuits and recriminations between them have been dragging on for years, but Tsutomu's clearly the one who was at fault.
