I don't know if Casio was a sponsor for the event, but my guess is they weren't. Despite this, I think they should make a Watch to commemorate their victory. Perhaps a Baby-G, it would be more fitting. Or may be 2 G's, 1 for home and 1 for away colors. I really like the color scheme of their uniforms. It would make for a nice G.
Anyways, just some wishful thinking.
Congrats to Japan on their victory. Lord knows they need it nowadays.
