"Shakeys, Pizza Hut, Dominos, Pizza California, Farmers, etc. as well as a lot of regional and local outfits help to fill the Japanese craving for pizza. Some offer delivery services to take care of those Japanese folks who'd rather eat in. Sizes are small and prices rather high, though, so if you come down to Japan and decide you want to phone out for pizza think carefully about the sizes and how hungry you are. A small size is about 20cm (7.9 inches), a medium 25cm (9.8 inches) and a 'large' pizza is a massive 35cm (13.8 inches) and is intended to serve 4 to 5 people! Prices range from about 800 - 900 yen ($7.40 U.S. to $8.33) for a small pizza to about 2, 800 yen ($25.93 U.S.) for a large pizza." - http://www.tanutech.com/japan/jpizza.html
