JJ refers to the contour of the bead seat of the wheel. (its the style found mainly on japanese wheel manufacturers, you should look for this when replacing wheels as it is found is a superior to non-jj-spec wheels)
What Does The JJ Mean In Wheel Size 16 X 7JJ?
That designation means that your wheel is 16' in diameter and 7 inches wide.
Not sure what the jj is, but I don't believe it is relevent. I will check manuals at work tomorrow and leave a comment under my answer.
