Personalised, Student-Centred Learning

Inquiry-led learning helps students build on their strengths, explore their interests, and take ownership of their learning journey.

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

Multicultural, Inclusive Community

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.

Leadership Development

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.

Building Towards K12 Education

OWIS Tsukuba is currently accepting admissions for Early Childhood Education to Grade 6 (ages 3-12)

We intend to open a new grade every year, with Grade 12 opening by 2031

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.
