Research from Japan Highlights Positive Connection Between Video Gaming and Mental Health
Recent research from Japan has revealed a beneficial link between video gaming and mental well-being, utilizing an extensive dataset and natural experimental conditions. The study emphasizes that gaming consoles, such as the Nintendo Switch, can notably enhance mental health, particularly among adolescents, countering the usual perception that gaming has detrimental effects.
Comprehensive Analysis and Key Findings
A recent study conducted in Japan analyzed 97,602 survey responses from individuals aged 10 to 69 during the COVID-19 pandemic to explore the effects of video gaming on mental health. The research revealed that owning a game console, particularly the Nintendo Switch, was associated with significant improvements in mental well-being. Notably, the Nintendo Switch demonstrated more pronounced benefits for adolescents compared to other consoles.
The study utilized machine learning techniques to assess the varying impacts of different gaming consoles. Findings indicated that while the PlayStation 5 offered modest benefits—improving mental health by 0.12 standard deviations and life satisfaction by 0.23 standard deviations—the Nintendo Switch showed more substantial gains, with mental health improving by 0.60 standard deviations among its users.
Methodology and Team Insights
The research team, which included experts from Osaka University, Hamamatsu University School of Medicine, Takasaki City University of Economics, the National Graduate Institute for Policy Studies, and Nihon University, employed a novel natural experimental design. By examining data from lottery systems for game consoles during the COVID-19 supply shortages, they established a clear causal relationship between gaming and enhanced mental health.

Challenging Stereotypes and Broader Implications
Hiroyuki Egami, PhD, Assistant Professor at Nihon University, remarked: “Our results challenge the prevailing belief that gaming is inherently harmful or offers only fleeting enjoyment. Instead, we have demonstrated that gaming can positively impact mental health and life satisfaction for a diverse range of individuals.”
Egami continued, “Previous research often relied on correlational data, which can only suggest associations rather than direct causation. Our natural experimental approach provides robust evidence that gaming actually enhances well-being, rather than merely being linked to it.”
Md. Shafiur Rahman, PhD, Senior Assistant Professor at Hamamatsu University School of Medicine and co-author of the study, added: “As an epidemiologist, I have encountered many concerns about the negative effects of gaming. This study’s rigorous methodology provides a significant challenge to those concerns and underscores the necessity for a more nuanced perspective on digital media’s impact on health.”
Specific Findings Across Different Consoles
The research highlighted that while the PlayStation 5 offered relatively minor psychological benefits for younger users, the Nintendo Switch delivered more substantial mental health improvements. These results question the broad stereotype that video games are universally detrimental to children and stress the importance of considering factors such as gaming platforms, genres, and styles in research and policy development.
