The Incident at Tokoha University: A Professor's Controversial SNS Post
In late February 2026, a post on X (formerly Twitter) by a professor at Tokoha University in Shizuoka, Japan, ignited widespread debate within the higher education community. The post mocked Prime Minister Sanae Takaichi by suggesting nicknames like "Kōutsu" (high depression) or "Ūtsu City" (depression city), playing on her surname "Takaichi" and the Japanese kanji for depression (鬱). This remark, made shortly after Takaichi's confirmation as Japan's 105th Prime Minister on February 18, 2026, quickly drew criticism for trivializing mental health issues and undermining professional decorum expected of academics.
The professor's account was deleted amid the backlash, but screenshots spread rapidly across social media, highlighting the risks of personal opinions clashing with institutional roles in Japan's tightly knit academic world.
Profile of Professor Hamakawa Sakae and Tokoha University
Tokoha University, a comprehensive institution in Shizuoka Prefecture with 10 faculties and 19 departments, emphasizes ethical conduct rooted in its founding principles. The university serves around thousands of students across campuses in Shizuoka, focusing on practical education in fields like pedagogy and social sciences.
Professor Sakae Hamakawa, from the Faculty of Education's School Education Course (social studies emphasis), holds a PhD in Literature and specializes in ancient Chinese history. As course head and deputy director of the Teacher Training Support Center, he teaches subjects like Oriental History Overview. His research, published in journals like Historical Studies, explores topics such as environmental development in ancient China's Loess Plateau.
This background in education and history amplifies concerns, as faculty in teacher-training roles model conduct for future educators.
University's Official Response and Commitment to Guidelines
On February 26, 2026, Tokoha University issued a statement on its website without naming the professor, confirming an "inappropriate private post equivalent to slander against others." The university affirmed its action norms—respecting personalities, avoiding harm, and eliminating discrimination—and pledged "strict measures." To prevent recurrence, it announced new guidelines for faculty SNS usage, including awareness training.Tokoha University Official Statement
This proactive step aligns with growing trends in Japanese higher education, where institutions balance faculty expression with reputational safeguards.
Public Reaction and Trending Discussions on X
The post trended on X, with users decrying it as insensitive to depression sufferers—a stigmatized issue in Japan, where suicide rates remain high despite awareness campaigns. Critics questioned the professor's suitability for education, while some defended it as political satire. Media outlets like Sankei News and J-CAST amplified the discourse, noting past inflammatory posts by the professor.
- Over 10,000 engagements on key threads within hours.
- Calls for accountability from alumni and parents.
- Debate on expression vs. harm, echoing national SNS regulations.
Political Backdrop: PM Takaichi's Rise and Public Sentiment
Sanae Takaichi's ascent to Prime Minister followed her LDP presidency win and parliamentary vote on February 18, 2026. Known for conservative stances on security and constitution revision, her leadership has polarized opinions. Post-election analyses noted "Takaichi depression" memes reflecting supporter letdown, which the professor quoted.
In higher education, such political commentary risks alienating stakeholders, especially amid Japan's push for global university rankings and international collaborations.
Mental Health Implications and Academic Responsibility
Japan's mental health landscape, with over 1.2 million annual depression diagnoses per government data, makes lighthearted jabs problematic. Academics, particularly in education, bear heightened responsibility to foster inclusive environments. The incident underscores how SNS can perpetuate stigma, impacting student well-being.
Universities increasingly integrate mental health training, viewing faculty as role models.
Precedents: Other SNS Misconduct Cases in Japanese Academia
This is not isolated. Recent examples include:
- Tsukuba University associate professor's February 2026 posts claiming low-ability foreign students, prompting university apology.
90 - Tokyo University's 2019 special associate professor discriminatory tweets.
93 - Gunma University's 2017 professor fired for student slander on Twitter.
These cases reveal patterns: swift deletions, institutional probes, and policy reinforcements.

Tokoha's planned guidelines mirror peers like Kindai University and Japan University of Economics, which outline:
- Distinguish personal vs. professional accounts.
- Avoid harmful, discriminatory, or confidential content.
- Report incidents promptly.
- Annual training on privacy and ethics.
National bodies like MEXT encourage such frameworks to protect institutional integrity.

Balancing Academic Freedom with Professional Ethics
Japan's Constitution Article 21 guarantees expression, but universities invoke service regulations for discipline. Courts often uphold dismissals for reputational harm. This case tests boundaries: satire vs. slander, personal views vs. educator duty. Experts advocate nuanced policies promoting discourse without toxicity.
Impacts on University Reputation and Student Recruitment
Scandals erode trust, affecting enrollment—Japan's declining birthrate intensifies competition. Tokoha's response aims to mitigate damage, signaling commitment to ethics. Prospective students and parents scrutinize faculty conduct via platforms like Rate My Professor.
