Japan’s adult entertainment industry, known as the “water trade,” is massive in scope and scale. In a cultural shift, there is now a burgeoning industry for women in search of young, attractive male partners. Tweaking the age-old laws of sexual supply and demand, where women provide physical companionship to their clientele, a host boy's main commodity is not his body but his emotional support. Welcome to The Great Happiness Space: Rakkyo Café. The club's owner, Issei (a young 22 years old), has a staff of 20 boys all under his training to become the top escorts of Osaka's underground love scene. Not everyone is up to the task. Every year, 100-200 boys apply to become a host at Rakkyo Café, one of Osaka's top host clubs. Only one or two make the cut. During their training, they learn how to dress, how to talk, how to walk and, most importantly, how to fake relationships with the girls who become their source of income. Interviews with Issei, once Osaka's number one host boy, and Rakkyo veterans Kazuya and Ryoma, educate us on the training of becoming a successful host. First, you have to hook a girl. Hosts-in-training congregate on a central bridge in Dotonburi, a shopping arcade with heavy foot traffic. With boldness atypical of this reserved culture, host boys use every method they know to pick up women. Join us as Osaka’s number one host boy takes us on a journey through the complex and heart-wrenching world of love for sale in the Japanese underground.
