Women in Shimane Prefecture have the most beautiful facial skin among the nation's 47 prefectures, while those in Gunma Prefecture are the least blessed in terms of skin condition, according to a major cosmetics manufacturer.

Pola Inc.'s annual Nippon Bihadaken Grand Prix 2014 (Japan Beautiful-Skin Prefecture Grand Prix 2014) announced its rankings on Monday. Women from the 47 prefectures who underwent the firm's proprietary skin analysis process took part in the event.

Shimane, Kochi and Ehime prefectures took the top three slots thanks to the shorter duration of daylight and higher humidity, according to the company's analysis.
