Why Sexual Activity Is Declining in the U.S. and Japan

Why Sexual Activity Is Declining in the U.S. and Japan

The “sex recession” has been well documented in the United States and continues to draw attention in the media, public health, and sexuality fields. National surveys show clear declines in partnered sex across age groups—not only among young people, but among adults more broadly. Americans are having less sex than they did 10 or 20 years ago, shaped by changing relationships, growing stress, digital life, and shifting social norms.

But the U.S. is not alone. Around the world, sexual activity is changing in noticeable and sometimes dramatic ways. One country receiving increasing attention is Japan, where rising rates of sexual inactivity have become a major societal and public health concern.

A new scoping review examining sexual inactivity in Japan sheds light on why these trends are accelerating—and what they reveal about modern sexuality across cultures.

Japan’s Sexual Inactivity: What the Research Shows

The scoping review synthesizes decades of studies documenting Japan’s trends of partnered sex. Generally, there is indication that sexual activity has dropped and it is not driven by one single factor. Instead, it emerges from a mix of economic pressures, cultural expectations, emotional well-being, gender roles, and evolving relationship patterns.

Some key findings include:

  • Sexual inactivity has increased over time: While there have been fluctuations since the 1970s, the general trend shows more people—both single and married—having less sex.

  • Singlehood is rising: Among adults ages 25–39, singlehood has increased, with slightly higher rates among men.

  • Sexual dissatisfaction is common: A recent study showed that half  of married men and one in four of married women ages 40–89 reported dissatisfaction with their sex life

  • Many remain sexually inexperienced into adulthood: About half of people in their mid-twenties reported no sexual experience, and ~10% had not had sex by their 30s.

  • Engagement with sex work varies widely: Due to different legal and cultural norms, (non-penetrative) sex work is less stigmatized in Japan, with engagement ranging from 3% to 60% depending on age, gender, and sample.

  • Language reflects cultural nuance: Japanese includes separate slang terms for male virgins depending on whether they have or have not engaged with commercial sex workers—a distinction not commonly seen in Western contexts that may 

  • Interest in sex is declining: Between 1% and 50% of people (depending on the sample) reported having no or limited interest in sex, while pornography use has stayed the same or increased.

These findings highlight profound shifts in how people relate to intimacy, desire, and relationships.

Social and Economic Stressors Are Major Contributors

Many studies point to work stress and economic pressure as central reasons for declining sexual activity. Long work hours, job insecurity, and chronic stress reduce opportunities for connection and diminish desire for partnered sex.

Even though average work hours in Japan have decreased slightly over recent decades, the workload remains intense: nearly 1 in 3 men and over 1 in 7 women still work more than 50 hours a week.

Japan’s labor culture is well known for its demands—but its impact on sexuality is rarely discussed. The review shows that economic stress affects not only frequency of sex but also people’s ability to form relationships and sustain emotional intimacy.

Rising Social Isolation and Shifts in Dating Norms

A growing number of people in Japan report limited social interaction outside work and home. This includes:

  • fewer opportunities to meet potential partners

  • more time spent alone

  • declining participation in dating or romantic activities

Digital technology provides entertainment, connection, and escape—but can also reduce in-person interaction and contribute to intimacy avoidance.

Some individuals shared that dating feels emotionally taxing or time-consuming. Others described a sense of “dating fatigue,” or reluctance to pursue relationships in a society already marked by high stress and competition.

(Some) Shifting Cultural Norms

Cultural norms strongly shape how people understand sexuality. In Japan, sexual inactivity has become increasingly normalized, especially among women.

Other cultural factors include:

These factors interact in complex ways with personal, relational, and societal expectations.

The Role of Pornography, Solo Sexuality, and Changing Desires

Several studies explored the role of pornography and masturbation in sexual activity patterns. Generally, porn and masturbation are sometimes used as a substitute for partnered sex due to:

  • convenience

  • emotional safety

  • avoidance of stress or expectations tied to relationships

However, the review emphasizes that pornography alone cannot explain the decline in partnered sex; rather, it interacts with broader social, cultural, and economic shifts.

What Japan’s Trends Reveal About Global Sexuality

Japan’s rising sexual inactivity is often sensationalized in the media, but the research offers a more nuanced perspective: sexual behavior is shaped by societal pressures, mental health, cultural expectations, and relational opportunities.

When compared to the U.S., several parallels emerge:

  • rising economic insecurity

  • increased loneliness and isolation

  • shifts in partnership norms

  • changing gender expectations

  • declines in mental health

  • the normalization of sexual inactivity

  • increased solo or tech-mediated sexuality

While the U.S. is not seeing changes at the same scale, the underlying patterns reflect broader global shifts.

Interestingly, there is evidence to suggest that Japan’s average age of sexual debut is older than many Western countries. But, because most research focuses on Western populations, it can be difficult to understand these patterns in a wider global context.

Why This Matters for Sexual Health Professionals

For sexual health professionals, Japan’s data serves as a powerful reminder:

Sexual inactivity is not simply about libido or personal choice—it is deeply connected to the cultural, economic, relational, and psychological conditions in which people live.

Understanding these patterns helps us:

  • better support clients who feel shame about sexual inactivity

  • recognize the role of stress, isolation, and cultural expectations

  • challenge myths that sexual inactivity reflects personal failing

  • adopt more compassionate, context-driven approaches to care

As professionals, we can help individuals and couples navigate changing sexual landscapes while promoting connection, communication, and well-being.

Looking Ahead: A Global Shift in Sexuality?

The question of why people are having less sex is far more complex than most headlines suggest. Japan’s data offers a window into how modern life—its pressures, technologies, and evolving values—shapes intimacy.

As more countries report similar trends, the conversation should focus less on “crisis narratives” and more on:

  • how people form meaningful connections

  • what emotional and relational needs look like today

  • how social conditions shape intimacy

  • what supports people need to thrive

SHA will continue exploring these themes and offering research-informed, sex-positive perspectives on global sexuality.
