Friendship Marriages Gain Traction in Japan as Alternative to Traditional Unions
Rise of Friendship Marriages in Japan
An increasing number of people in Japan are opting for “friendship marriages,” a form of partnership that prioritizes companionship and mutual support over romantic or sexual relationships. These arrangements, which focus on shared values and practical goals, are particularly popular among LGBTQ individuals and those uninterested in conventional romantic partnerships.
Friendship marriages involve legally recognized unions where partners agree to build a life together based on friendship, often with the aim of achieving stability, raising children, or accessing social security benefits. Unlike traditional marriages, these partnerships explicitly exclude romantic or sexual expectations, allowing individuals to maintain separate personal lives while collaborating on shared responsibilities.
A Case Study: Satsuki and Minato
One such couple, Satsuki and Minato, both in their 30s, have been in a friendship marriage since 2021. They live together and are raising a child, splitting household chores and participating in family outings and social events. “We’re not each other’s type,” Minato said, likening their relationship to “comrades-in-arms.” Satsuki described Minato as “a not-too-close cousin,” highlighting a strong bond grounded in mutual respect and friendship rather than romantic attachment. The couple maintains separate romantic lives, with intimacy absent from their partnership.
The rise of friendship marriages reflects broader societal shifts in Japan, where traditional marriage rates have declined. According to the Ministry of Health, Labour and Welfare, the number of marriages in 2023 fell to 489,000, the lowest since 1933, with many young adults citing economic pressures, career demands, or disinterest in romantic relationships as barriers. Japan’s fertility rate, at 1.2 births per woman in 2023, remains among the world’s lowest, prompting alternative family structures like friendship marriages to address desires for parenthood or companionship.
Societal Context and Future Implications
These partnerships are often facilitated by agencies like Aile Marriage, which reported a 20% increase in inquiries for friendship marriages in 2024 compared to the previous year. Such agencies match individuals based on compatible values, lifestyles, and goals, catering to diverse groups, including asexual individuals, single parents, and those in the LGBTQ community. Japan’s lack of legal recognition for same-sex marriage—despite public support, with 72% favoring legalization in a 2023 Asahi Shimbun poll—has driven some same-sex couples to choose friendship marriages as a practical alternative for legal and social benefits.
The trend also aligns with global movements toward non-traditional relationships, seen in countries like South Korea, where “sologamy” and platonic partnerships are emerging. In Japan, friendship marriages offer a solution to societal challenges like loneliness and an aging population, with 29.1% of people aged 65 or older in 2024, per government data. By fostering stable, non-romantic households, these unions provide emotional and financial security, appealing to those seeking alternatives to conventional family models.
While still a niche practice, friendship marriages are gaining visibility through media and online platforms, with X posts highlighting personal stories of couples who value their platonic partnerships. As Japan navigates its demographic and social challenges, friendship marriages represent a growing acceptance of diverse approaches to building meaningful connections and family structures.
