The other day I got a pizza delivery menu through my mailbox, watch the video to see some details: http://www.youtube.com/watch?v=PbwCmfh1Rak
You can check out the menu online, in English, here.
Pizza is not nearly as common as it is back home here in Japan, but it's by not a huge rarity, just expensive. I see Pizza-La delivery scooters out on the roads every once in a while, and there are even smaller independent pizzerias around town. You can even get single slices at my grocery store for around $3, but aren't so great since they've been sitting out all day. But they are just as ridiculous as the ones on the Pizza-La menu.
