Japan's oldest "love doll" manufacturer wants to strip the sex toys of their seedy image and encourage people to see them as works of art instead.

"Even now there is still a stigma," said a spokesperson for Tokyo-based sex doll maker Orient Industry, which recently celebrated its 40th anniversary with a three-week exhibition showing the evolution of its dolls that drew over 10,000 visitors.

"But at our exhibition there were lots of men and women visitors — more women than men, in fact," he said. "There were young and old, men and women, a really wide range of people. I think people came because they had heard the reputation of how beautiful our dolls are. We want to get rid of the stigma."
