Discovering the Health Literacy Gap Among University Students in Japan
International students in Japan face unique challenges when it comes to maintaining their health, and a groundbreaking study from Tohoku University sheds light on a critical factor: health literacy. Published in Annals of Medicine on March 28, 2026, the research titled "The role of health literacy in the association between nationality and health status among university students: a cross-sectional study" reveals that while access to healthcare is available, understanding how to use it effectively plays a decisive role in health outcomes.
The study, conducted by Akindele Abimibayo Adeoya and colleagues from Tohoku University's Graduate School of Biomedical Engineering, involved 1,366 students from universities across six of Japan's eight regions. Self-reported health status showed 73% of Japanese students rating their health as good, compared to only 61% of international students. This disparity persisted even after adjusting for sociodemographic and educational factors, highlighting deeper issues.
Defining Health Literacy and Its Measurement
Health literacy refers to the degree to which individuals can access, understand, appraise, and use health information to make informed decisions about their care. The researchers employed the European Health Literacy Survey Questionnaire (HLS-EU-Q47), a validated 47-item tool adapted for Japan, categorizing levels as inadequate, problematic, or sufficient.
Strikingly, 92% of all participants had limited health literacy (inadequate or problematic), aligning with prior Japanese studies showing high rates among young adults. Unexpectedly, international students scored higher on health literacy than their Japanese peers, possibly due to prior exposure to diverse health systems or greater motivation to navigate Japan's complex medical landscape.
Key Findings: How Health Literacy Mediates Health Disparities
Among students with sufficient health literacy, international students reported better health status than Japanese students, reversing the overall trend. In contrast, international students with limited health literacy faced significantly poorer outcomes. Statistical analysis confirmed health literacy as an effect modifier: the nationality-health status association was strongest in the low health literacy group (odds ratio indicating higher risk for internationals).
- Japanese students good HS: 73%
- International students good HS: 61%
- Limited HL prevalence: 92% overall
- Higher HL internationals outperform Japanese peers
This suggests that barriers like language, cultural differences, and unfamiliarity with Japan's healthcare—insurance, appointments, terminology—exacerbate risks for internationals lacking strong health literacy.
The Rise of International Students in Japanese Higher Education
Japan's international student population has surged past 435,000 as of June 2025, exceeding the 2033 target of 400,000 by eight years. Universities like Tohoku, a top research institution in Sendai, host thousands, promoting global exchange. Yet, rapid growth brings health challenges: cultural shock, academic stress, part-time work limits, and navigating the National Health Insurance system.

Factors Influencing Health Literacy in University Settings
The study identified sociodemographic predictors: age, gender, year of study, and region affected HL levels. International students' advantage may stem from multilingualism or self-selection—those adapting well to Japan likely possess better skills. Japanese students' lower HL echoes national trends, where comprehensive health literacy lags behind Europe (Japan average score lower per prior surveys).
| Factor | Impact on HL |
|---|---|
| Nationality | Intl higher than Japanese |
| Academic Year | Higher years better HL |
| Gender | Females slightly higher |
Step-by-step, low HL leads to poor preventive behaviors, delayed care-seeking, medication errors—compounding stress for internationals far from home.
Beyond Access: Systemic Barriers in Japan's Healthcare for Students
Japan boasts universal coverage via National Health Insurance (kokumin kenko hoken), mandatory for students, covering 70% costs. Yet, internationals struggle with kanji-heavy forms, appointment systems (yoyaku), and over-the-counter drug distinctions. Cultural norms like stoicism delay help-seeking. The study underscores that equal access doesn't guarantee utilization without literacy.Read the full study here.
Tohoku University's Commitment to Student Wellbeing
As a leading national university, Tohoku integrates health promotion via its Student Health Care Center, providing checkups, mental health support, and English resources. Specially Appointed Professor Ryoichi Nagatomi emphasized: "Reducing this gap starts with improving health literacy—making information clearer and adapting communication." Initiatives include peer support, workshops, and digital tools for internationals.
Challenges Across Japanese Universities
With 800+ universities hosting internationals, similar issues prevail. JASSO reports rising numbers from Asia (China, Nepal, Vietnam top sources). Mental health crises, post-COVID isolation amplify needs. Limited HL correlates with higher chronic stress, poor diet, sleep—vital for academic success.

Practical Solutions and Actionable Insights
Universities can implement:
- Multilingual health apps and videos explaining systems.
- Orientations with HL training: insurance enrollment step-by-step, pharmacy navigation.
- Peer mentoring programs like Tohoku's Help Desk.
- Collaborations with MHLW for simplified materials.
- Screening via HLS-EU-Q47 at intake.

Future Outlook and Research Directions
This Tohoku-led study calls for longitudinal follow-ups, interventions testing HL programs' efficacy. As Japan globalizes higher ed, prioritizing HL ensures equitable outcomes, boosting retention and contributions from intl talent. Balanced views from stakeholders—students, admins, policymakers—promise healthier campuses.
