Waseda University professor Toshimitsu Shigemura believes Kim John Il died in 2003. The person leading the country today is referred to by family as "the current shogun." Japan Today has more on this controversy.
AP reports that the either the real Kim Jong Il or the person acting in his place "was absent from Tuesday's celebration to mark North Korea's 60th anniversary, fueling speculation that he was gravely ill."
It looks as if nobody has a clue what is happening in North Korea.
