There are, however, rules that members have to follow. They can write letters of up to two sheets on designated paper. A pair can send and receive letters up to five times without revealing their name or home address. If both parties wish to meet face to face, operators take care when exchanging contact information. After that, it is left up to the members, the Japanese publication had reported. So far, 32 pairs have set up face-to-face meetings, with romance blooming for 17 couples who have started a relationship. One participant, a 25-year-old Miyazaki resident, said the idea had brought back fond memories. "As a kid, I used to write letters to the girl I had a crush on," the man, who wished to remain anonymous, told AFP. "I like how old-fashioned letters are. That made me want to join the programme."
