When Tsuneo Akaeda opens his mouth to speak about the sex culture of Japan's younger generation, a tirade of sexual slang all the more surprising because of his professional and smart-suited exterior flows out.
The 57-year-old obstetrician and gynecologist is known as "Roppongi's doctor" among the young Japanese girls who frequent one of Tokyo's busiest entertainment districts.
"It shocks me to work as a gynecologist in Roppongi because I see so many young girls who have crazy sex lives without any concerns about their health," said Akaeda, who has run a clinic in the area since 1977.
