Da Vinci Code Sausage!

Two posts in one day! O_O. Yeah, so on to the Sausage. I had a prodigious thought the other day while watching the OP to Lucky Star. The blue-haired girl holds up three fingers on each of her hands. Normally, this three fingered sign indicates Eastside, which would mean on the East Coast. I started thinking and this is what I came up with. This is a Japanese anime, so East Coast couldnt possibly be the case. Then I noticed her other hand, which had a three. http://maps.google.com/maps?f=q&hl=en&q=Japan&ie=UTF8&z=17&ll=31.951525,130.220786&spn=0.006254,0.009978&t=h&om=1
I did some research on Google and found this. There is a Japanese highway, Highway 3, that if you look on the eastern side of it, you will see a city eventually. You must be going north because the girls ducked down, then went up, which gives direction. Anyway, back to the city. This city obviously contains a store that sells, you guessed it, the world's best sausage. (Kami, if you can read that big red kanji, plz tell me if that says Sausage, thankies)
