Windmill...

LOL! I had to look at the picture several times to understand what you meant by the Windmill item but now that you mention it, the item does have a very similar shape to the swastika.

However I think that it was merely a coincidence. After all, don't most of those "windmills" have the same shape? Maybe they just gave it to Yoshimitsu because it makes him appear more... colourful?:D
