According to the company, Wit Inc, the daily rate on each thigh is $121, and campaigns have so far included ads for the Seth MacFarlane and Mark Wahlberg movie "Ted" and the band Green Day.
According to the company, women who apply must be at least 18 years old, and they need to have a seemingly small minimum of 20 friends on social media sites.
The PR firm encourages the women to wear miniskirts with long socks in order to draw attention to the sticker.
Ad agency CEO Hidenori Atsumi said the thigh stickers are "absolutely perfect" because "this is what guys are eager to look at and girls are eager to expose."
The women then take photos of themselves wearing the sticker in at least two different public locations and upload them to the Internet. The result is that fairly high-quality and thoughtfully posed pictures of their advertisements proliferate on social networking sites.
So far, more than 3,000 women have applied to wear the thigh sticker advertisements.
