Tokuda certainly looks like he's enjoying life, saying he's healthier now than he's been in years. So are sales of his DVD's, primarily among middle-aged and elderly buyers.

"In his generation, Tokuda is a superstar," says Gaichi Kono, an adult video director who has worked with Tokuda.

"He encourages older people to think, I can do this because that old man can do this."

Ruby Productions produces Tokuda's movies and specializes in elderly porn videos. It's a genre they helped pioneer by accident.

Ryuichi Kadowaki, president of Ruby Productions, says they started producing adult videos with people in their 30's to good sales. They creeped up to 40 year old actors and they sold even better. Kadowaki says they went up to actors in their 50's, then 60's, and now they're producing an entire line of adult videos with actors in their 70's.

And their star, says Ruby, is Tokuda. "To be honest, I don't understand why people are buying these videos," he says. "I think our older customers must feel a sense of security by watching videos with an actor who is in the same generation."

Ruby says it's targeting the elderly audience and considering selling videos in retirement homes. Ruby also says it's just completed a deal to release some of Tokuda's movies in the U.S.

Japan does have a higher percentage of people over the age of 65 than any country in the world. Ruby Productions says it's just meeting a demand of an aging Japanese society.

Tokuda says his friends are envious, because he's in a job where he's valued, something many seniors lack. "Seniors get depressed because they don't have anything to do. They go crazy," says Tokuda.

Tokuda hopes to work until he's 80 or even older. Giving it his all, he says, until the end.
