This is a very deceptive forgery.  The difference in color is a clue, but the color of the genuine varies.  The most consistent difference is in the two lines of the outer frame.  The genuine has two lines close together with a wide white space before the rest of the design.   The Wada forgeries have two thicker lines and a small white space in all positions.
