The things you learn online…  In this week’s issue of Time Magazine there is an um, ah, er, interesting piece on Japanese pornography featuring the elderly.

Japan is repeatedly found to be one of the most sexless societies in the industrialized world. The WHO reported in March this year found that one in four married couples in Japan had not made love in the previous year, while 38% of couples in their 50s no longer have sex at all. Yet, at the same time, the country has seen a surge in demand for pornography that has turned adult videos into a billion-dollar industry, with “elder porn” one of its fastest growing genres.

Tokuda’s exploits have proved to be a goldmine for Glory Quest, which first launched an “old-man” series, Maniac Training of Lolitas, in December 2004. Its popularity led the company to follow up with Tokuda starring in Forbidden Elderly Care in August 2006. Other series followed, and soon elder porn had revealed itself as a sustainable new revenue stream for the industry. “The adult video industry is very competitive,” says Glory Quest p.r. representative Kayoko Iimura. “If we only make standard fare, we cannot beat other studios. There were already adult videos with Lolitas or themes of incest, so we wanted to make something new. A relationship between wife and an old father-in-law has enough twist to create an atmosphere of mystery and captivate viewers’ hearts.”

Japan’s adult video industry is believed to be worth as much as $1 billion a year according to industry insiders, with the largest rental video store chain Tsutaya releases about 1,000 new titles monthly, while and the mega adult mail-order site DMM releases about 2,000 titles each month. Although films featuring women in their teens and 20s are the mainstay of the industry, a trend toward “mature women” has become evident over the past five years. Currently, about 300 of the 1,000 adult videos on offer at Tsutaya, and 400 out of the 2,000 at DMM, are “mature women” films.
