Nana Natsume is a well-known and award-winning Japanese AV idol and celebrity. She is one of the many Japanese adult video starlets that has been able to successfully cross over to more mainstream media. She was also awarded the AV Grand Prix by Tokyo Sports magazine for 2005. Today I was struck by her presence on a massive billboard (across from 109) designed to help stop the spread of sexually transmitted diseases in Japan. The youtube video, as abstract as it appears to be, states that 1 in 15 Japanese youth have an STD.
