Photos: See the 3ft Japanese man who profits from looking like a child in X-rated films

24-year-old 3ft Japanese man, Kohey Nishi, who's also a computer programmer, capitalises on looking like a child in porn and earns a living by having sex with older women.

Nishi has an incurable disease called 'mucopolysaccharidosis' which halts growth and leaves him vulnerable to spinal cord injuries.

Although he struggles to stand for longer than five minutes because of his condition, it does not bother him as most of his porn shoots are in a bed. He also cannot open a plastic bottle or hear in his left ear due to the condition.

Nishi had a 'miracle' bone marrow transplant which has since stopped the disease's development. He however admits that the pressure from being famous gets to him sometimes and he struggles to sustain an erection in front of porn film crews.
