New Japanese commercial.
Seems legit?
Spot is for some kind supplement (that improves eyesight? Your throwing arm?) from the Sato Pharmaceutical Corporation.
Here's a previous commercial.
He's apparently the Official Throwing Arm of Sato.
He doesn't have the throwing arm he had 11 years ago, when he informed all of Major League Baseball that he was legit by gunning out Terrence Long (video).
