Cosmetics website “LC love cosmetic” (  shared the results of a quick-and-dirty survey it conducted about women’s bust sizes, and the surprising facts are certain to titillate men (and women) with certain – ahem – outsized preferences.

The website, which bills itself as being “for two persons who love,” posted a list of Japan’s 47 prefectures arranged by average cup size, and for persons who love two large, shining orbs, there are no better places in Japan than Gifu and Kyoto Prefectures, where E is the norm.

For those who don’t like speed bumps between themselves and their lovers, Saitama Prefecture and its A-cup average beckon. The national average fell between B- and C-cups, with a majority of prefectures in East Japan at B and a majority of those in West Japan at C.

The handy map above shows that, on matters of size, the Kinki and Chubu Regions of Japan are prime areas for booby hunting. LC love cosmetic could not be quite sure why these differences exist, but offered that diet is related to the development of breasts. Wonder what women in Gifu and Kyoto are eating . . . ?
