In Japan, men enjoy fictitious love at a Kyabakura, cabaret type entertainment for men which charge customers hourly, a Soapland, a sort of high-end prostitution house, or other sex industries. There are fundamental differences of services in Kyabakuras and Soaplands, for instance, but men go those places looking for emotional fulfillment rather than simple act of sex. In the real world, a man may be rejected by a woman or have conflicts, but if they go to one of those places as a customer, they treat you with hospitality.
From the supply side perspective, this type of work involves intensive emotional and physical labor. In order to make the clients believe that they are sincerely favored and keep them coming back, the girls blur the line between work and private intentionally. The more clients she gets, the higher income she earns. Many Japanese men play the game by the rules, but some inexperienced customers confuse the sales pitch with real love.
Traditionally in Japan, work division between men and women have been strict. The influence of America and other Western cultures changed Japan significantly, but still men tend not to contribute to housework, and women tend not to go to social gatherings with spouses. Some men can't even cook a fried egg, and many social gatherings don't require bringing a significant other. Throwing a house party and inviting colleagues and clients with their spouses is against the traditional Japanese model, because it requires a house wife to work as a host.
Even though most of Japanese women are not equipped to organize and host such parties, women who can entertain guests with well versed conversations and sophisticated manners are greatly sought after by politicians. Many Japanese politicians and industry leaders use professional women for that purpose. Those women were geishas in the past, and hostesses of high-end clubs in more recent history. Some of them ended up as wives of those powerful men and kept contributing to their husbands' social successes.
While high-end clubs are not affordable by regular folks, Kyabakuras are within their reach. In both places, professionally trained women come to the table, join conversation while lounging with a drink. When a marriage turns sour and work is not rewarding, those professional women provide temporary emotional refuge to a man. This serves as an escape valve and is one of the reasons why Japanese divorce rate is low, even though they have significantly less frequent sex compared to the rest of the world population.
