With small class sizes (up to 18 students), teachers can give each child the attention and feedback they need to thrive.

Join a truly international school environment where diversity is valued and every child feels seen.

Through a culture of kindness, inclusion, and strong student support, OWIS Tsukuba helps learners develop a genuine sense of belonging and confidence.

Nurtured through Personal, Social, and Emotional Learning (PSEL), students build self-awareness, emotional regulation, confidence, and empathy.

With inquiry-led learning, student agency, and real leadership roles such as the House system and House captains, students practise responsible decision-making, teamwork, and calculated risk-taking.

OWIS Tsukuba Curriculum

At OWIS Tsukuba, we offer K12 international education that combines strong academic foundations with values-led development, helping students think critically, learn independently, and grow into confident international citizens.

1. Inquiry-Based – Students ask questions, explore curiosities, and engage with ideas through real-world, problem-solving learning experiences.

2. Student-Driven – Student-led projects build ownership, helping learners focus on their strengths, interests, and personal goals.

3. Research-Backed – We use evidence-based practices to strengthen learning outcomes, such as genre-based writing, Reader’s/Writer’s Workshops, Guided Reading, and dedicated Quiet Reading Time.

4. Place-Based – We connect curriculum concepts to real experiences, using local resources to make learning authentic, meaningful, and relevant.

5. Real-World Applicable – Learning is designed around practical application, strengthening numeracy and problem-solving students can use with confidence.

6. STEM Focused – Our STEM learning is strengthened through a dedicated Design, Innovation, and Technology strand, hands-on projects, and spaces that encourage experimentation and creative problem solving.

7. Scientific – Students build science skills through a clear framework (planning, investigating, analysing, evaluating), helping them think like scientists and apply learning with purpose.

8. Holistic – Our after-school activities, competitive sports, and enrichment programmes support character, confidence, teamwork, and personal passions.

10. Effective Educators – Learning is delivered by certified, experienced educators who guide students with expertise, consistency, and high expectations, supported by global best practices.
