I'm watching a replay of the Philadelphia Phillies and Seattle Mariners game and there's a large 3DS banner behind home plate. I wish I could post a screenshot of it, but the weird thing is with the exception of "3DS" and the Nintendo logo there's a bunch of words written in Japanese. At least it might be a bunch of words, it might be one word I don't read Japanese.
But my point is, obviously Nintendo is trying to do some advertising, so why are they putting up giant signs written in Japanese at an American baseball game? I don't think many are going to be able to understand it. Just seems really weird.
Edit-
here's a clip to a highlight of the game and you can clearly see the sign right in the opening seconds.
