I've been seeing this Softbank ad in the trains and at stations recently. I thought they were exaggerating when they said the gift would be a phone strap as big as a life-sized dog. Apparently the white dog is the mascot, whereas the protagonist in the ads is the black guy.
I guess they weren't kidding when the other day I saw a Softbank sales guy holding this up! Apparently, it's 30cm high and there are only 30,000 to be given away. And yes, only in Japan will you see phone straps this outrageous.
P/S: Don't ask me why Softbank is not a bank, but a mobile service provider.
Update 7 July 2009: Another gigantic poster, this time at Shibuya station.
