Illegal Drug Use in Japanese College Sports: Pressures, Scandals, and Calls for Reform
Japan’s collegiate athletic landscape has faced a growing crisis as multiple university teams grapple with incidents of illegal drug possession, sparking debates about athlete well-being, institutional oversight, and the pressures of competitive sports. The Nippon University American football program and Kokushikan University judo team have become focal points in this conversation, with cases raising questions about systemic challenges in Japanese sports culture.
What Happened: A Pattern of Scandals
The Nippon University American football team, one of Japan’s most prominent collegiate programs, made headlines in 2023 and 2024 when multiple players were arrested or referred to prosecutors for cannabis possession. According to Asahi Shimbun, at least five players faced legal action during that period, though the exact number remains unclear due to limited public records. The incidents occurred amid heightened scrutiny of college sports, where academic and athletic demands often collide.
More recently, in 2024, a judo athlete from Kokushikan University was arrested for drug-related offenses, marking the second major scandal involving elite collegiate athletes in under a year. While the specifics of the case are still under investigation, the incident has reignited discussions about the pressures faced by student-athletes in Japan.
Expert Insights: The Role of Pressure and Institutional Gaps
Experts in sports psychology and drug prevention have pointed to the intense pressures on Japanese student-athletes as a contributing factor. Dr. Akira Tanaka, a professor of sports science at Tufts University and a consultant for the Japan Sports Agency, noted, “The combination of academic rigor, athletic expectations, and societal stigma around failure creates a perfect storm for substance use.”

“Many athletes feel they must hide their struggles,” added Dr. Yuki Sato, a clinical psychologist specializing in collegiate sports. “The fear of disappointing coaches, families, or sponsors can drive them to seek temporary relief through substances.”
These concerns are compounded by gaps in institutional support. While Japan’s Japan Olympic Committee (JOC) has emphasized anti-doping initiatives, critics argue that mental health resources and education on substance use remain underfunded. “We need a cultural shift,” said Kenji Watanabe, a former JOC official. “It’s not just about punishment—it’s about understanding the root causes.”
University Responses: Denials, Investigations, and Reforms
Nippon University has not issued a public statement on the 2023-24 incidents, but internal documents obtained by Nikkei reveal that the athletic department initiated an internal review of its drug policies. The university cited “a commitment to fostering a safe environment for student-athletes,” though specifics of the reforms remain undisclosed.

Kokushikan University, meanwhile, confirmed the arrest of its judo athlete and stated We see cooperating with authorities. “We take these matters seriously and are reviewing our support systems for student-athletes,” a spokesperson said. The university has also pledged to strengthen its collaboration with the Japan Sports Association (JSA) to address similar issues.
Broader Implications: A Crisis of Trust and Accountability
The scandals have sparked a broader conversation about accountability in Japanese sports. Critics argue that the country’s rigid hierarchical structures—where coaches often hold disproportionate authority—can discourage athletes from seeking help. “There’s a culture of silence,” said journalist Rina Yamamoto, who has covered collegiate sports for The Japan Times. “Athletes are afraid to speak out, and institutions are slow to act.”
The incidents also raise questions about the effectiveness of Japan’s anti-doping framework. While the country is a signatory to the World Anti-Doping Agency (WADA) code, enforcement in collegiate sports remains inconsistent. A 2023 report by
