TELEGRAPH.CO.UK - June 22 - One critical new criteria for finding the perfect partner was recently added to Japan’s fast-paced dating world, with the launch of a new service that promises to find love based on DNA compatibility. Created by the dating company Nozze., which operates 21 branches across Japan, DNA Matching works with scientists at a Tokyo laboratory in order to decode the science of attraction and find the perfect match for its clients. Earlier this week, new government figures revealed that almost half of Japanese singles who wished to marry were unable to find a suitable partner, with 60% admitting they were not doing anything to change the situation. Satoru Fujimura, PR manager of Nozze., said: "We believe 50% of a person's attraction to another person is due to DNA. And the other 50% is environment. We believe that people with the most different types of DNA (HLA) make the best couples."
