Aoyama cites one man in his early 30s, a virgin, who can’t get sexually aroused unless he watches female robots on a game similar to Power Rangers. “I use therapies, such as yoga and hypnosis, to relax him and help him to understand the way that real human bodies work.” Sometimes, for an extra fee, she gets naked with her male clients – “strictly no intercourse” – to physically guide them around the female form. Keen to see her nation thrive, she likens her role in these cases to that of the Edo period courtesans, or oiran, who used to initiate samurai sons into the art of erotic pleasure…

Tomita sometimes has one-night stands with men she meets in bars, but she says sex is not a priority, either. “I often get asked out by married men in the office who want an affair. They assume I’m desperate because I’m single.” She grimaces, then shrugs. “Mendokusai.”

Mendokusai translates loosely as “Too troublesome” or “I can’t be bothered”. It’s the word I hear both sexes use most often when they talk about their relationship phobia. Romantic commitment seems to represent burden and drudgery, from the exorbitant costs of buying property in Japan to the uncertain expectations of a spouse and in-laws. And the centuries-old belief that the purpose of marriage is to produce children endures. Japan’s Institute of Population and Social Security reports an astonishing 90% of young women believe that staying single is “preferable to what they imagine marriage to be like”…

“It’s too troublesome,” says Kishino, when I ask why he’s not interested in having a girlfriend. “I don’t earn a huge salary to go on dates and I don’t want the responsibility of a woman hoping it might lead to marriage.” Japan’s media, which has a name for every social kink, refers to men like Kishino as “herbivores” or soshoku danshi (literally, “grass-eating men”). Kishino says he doesn’t mind the label because it’s become so commonplace. He defines it as “a heterosexual man for whom relationships and sex are unimportant”.
