He is a typical man of age - a few white hairs cover his round head and he wears dentures.
But 75-year-old Shigeo Tokuda sat on a movie set on Monday wearing just a silk kimono and loin cloth about to have sex on film with a woman who is younger than his daughter.
Tokuda is Japan's oldest pornographic movie star and was shooting his latest film in which he portrayed a master of sex.
The director said the films showed people that their sex lives did not have to end with old age, and in 16 years of making such movies Tokuda has acted up with women ranging from their 20s to as old as himself.
"I debuted at 59, and have played in more than 200 porno movies since then," he said, using his screen name, not his real one in an interview on the set.
"I wanted to challenge what ordinary people did not, so I decided to be a porno actor."
