Ai Aoyama is a sex and relationship counsellor who works out of her narrow three-storey home on a Tokyo back street. Her first name means "love" in Japanese, and is a keepsake from her earlier days as a professional dominatrix. Back then, about 15 years ago, she was Queen Ai, or Queen Love, and she did "all the usual things" like tying people up and dripping hot wax on their nipples. Her work today, she says, is far more challenging. Aoyama, 52, is trying to cure what Japan's media calls sekkusu shinai shokogun, or "celibacy syndrome".

Its population of 126 million, which has been shrinking for the past decade, is projected to plunge a further one-third by 2060. Aoyama believes the country is experiencing "a flight from human intimacy" – and it's partly the government's fault.
