Time Magazine has made an article about the new trend on japanese porn, apparently this new item is called “Elder porn” and is currently a hit in Japan. Yeap oldies japanese couple having sex is the new fetish for porn lovers.
Is not like it's weird that japanese people make up weird things, cause c'mon that's one of the countries that love more porn, so this is only a new niche that they has made up named “elder porn”.
Shigeo Tokuda is the biggest star on this “elder porn” and on an interview he made some statements: “ 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”. Maybe not their hearts but I can think in something else.
