Like China, Japan has a gender imbalance, in which one gender drastically outnumbers the other. But nowhere is the imbalance felt than in the country’s adult movie industry, where there are only 70 male porn stars and 10,000 female performers.

There are two indicators of how bad the shortage of male porn actors is in Japan. First, the title of the world’s oldest porn actor, according to the Guinness Book of Records, is held by Shigeo Tokuda, who turned 82 this 2016. The octogenarian still disrobes, but because of the downturn of the porn industry in Japan, he now makes only an average of 10 adult movies per year compared to 60 when he shifted to the industry in 2004, according to Tokyo Reporter.

Second, Shimiken, the busiest male porn actor in Japan, tweeted a “cry for help” in August 2014. He wrote, “In this industry … the number of male porn stars in Japan is less than that of Bengal tigers … With 4,000 new films every month, the number of male actors simply isn’t enough. This industry is like a hole in the wall that needs to get bigger!”

Because of excess capacity among Japanese female porn stars, one actress, Rola Misaka, was fortunate enough to be hired by an anonymous Chinese businessman in May 2015. The 22-year-old would work as the businessman’s personal assistant and shall be paid a whopping US$8 million (AUS$10.67 million) annual salary.

Outside the world of porn, the gender imbalance in Japan is actually in favour of males at birth – 1.06 males for every female – but it changes at ages 25 to 54, when it reverses to 0.98 male for every male. It worsens to 0.76 males for every female for elderly Japanese or those over 65 years old. But as of 2014, overall ratio is 0.95 males for every female.

Because of the male shortage, Shimiken had sex with 7,500 women over his 19 years as a porn actor. The deficit means he has to film 21 sex movies a week, but age is catching up on him. While for Tokuda, a monogamous relationship is still the ideal, adultery is necessary for the elderly for health reasons, too.
