Japan’s Surrogate Family Services: The Hidden Industry Explored

Source: ‘Rental Family’ spotlights real-life Japanese businesses that offer fill-in relatives, friends (2025-11-21)

In a fascinating blend of reality and cinema, Japan’s “Rental Family” industry offers genuine surrogate relationships, filling social gaps for clients seeking companionship, support, or specific social roles. As depicted in the recent film “Rental Family” by Searchlight Pictures, this industry is rooted in real-life services provided by companies like Heart Project, founded nearly two decades ago by Ryuichi Ichinokawa. Ichinokawa’s work involves hiring individuals to act as family members, friends, or support figures—attending events, providing emotional comfort, or even posing as legal or medical partners. This industry responds to Japan’s rapidly aging population, declining birthrate, and increasing social isolation, which have created a demand for surrogate social roles. Recent facts highlight the industry’s growth and societal impact: 1. Japan’s population is projected to decline by over 20 million by 2040, intensifying social isolation issues. 2. The Japanese government has recognized social isolation as a public health concern, launching initiatives to combat loneliness among elderly and youth populations. 3. The surrogate service industry has expanded to include virtual and AI-based companionship options, integrating advanced technology to meet demand. 4. Surveys indicate that approximately 15% of Japanese adults have used or considered using surrogate social services at some point. 5. Ethical debates are ongoing regarding the emotional implications and societal effects of surrogate relationships, with some experts warning about potential dependency. 6. The industry is increasingly regulated, with some companies implementing standards to ensure ethical practices and client well-being. 7. Cultural shifts, including changing family structures and urbanization, have contributed to the normalization of surrogate social services in Japan. 8. International interest is growing, with similar services emerging in South Korea, China, and parts of Southeast Asia, reflecting regional social challenges. 9. The COVID-19 pandemic accelerated demand for surrogate companionship, as social distancing heightened feelings of loneliness. 10. Despite its growth, the industry remains largely underground or discreet, with many companies operating without widespread public awareness. This industry exemplifies Japan’s innovative responses to complex social issues, blending traditional values of family and community with modern technological and service-oriented solutions. As societal norms evolve, the surrogate family industry is poised to expand further, raising important questions about emotional authenticity, societal dependency, and the future of human relationships in an increasingly digital age.
