Utilizing big honkin' displays for advertising purposes is nothing new, but East Japan Railway Company (JR East) and East Japan Marketing & Communications have decided to try "digital posters" out for reference. In short, ten 65-inch Sharp PN655R LCDs have been installed within "the internal concourse on the first floor of Tokyo Station's Yaesu South Entrance," and folks who stroll by can get a glimpse of whatever (the image changes each minute) in stunning 1080p. The goal here, as you might imagine, is to "evaluate the advertising effects of still image ad posters using large LCD panels displayed in a relatively busy gateway." If you're anxious to lay your eyes on the installation, you'd better hurry, as there's no guarantee that they'll remain after September. At least the video posted after the jump is forever.
