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.
