Tomorrow is International Sake Day. We'll be toasting our favorite Japanese rice liquor at midnight with a sake bomb. In the meantime, we'll start celebrating early with a list of 20 chesty Japanese gravure idols with supersized, extra-large breasts. Just like Godzilla toppling a Tokyo skyscrapper and Tom Selleck in "Mr. Baseball," these lovely ladies redefine what it means to be huge in Japan.
