Academics
Since expanding significantly over the past year, OWIS Osaka continues to strengthen its inquiry-led learning environment—bringing together a growing international community, enhanced programmes, and even more opportunities for students to thrive.
Our curriculum is grounded in inquiry-based learning and aligned with the International Baccalaureate (IB) framework, delivered in English within a diverse, supportive setting.
At OWIS, we balance strong academics with a student-centred approach, drawing on Montessori-inspired principles and engaging, research-informed teaching methods that focus on each child’s strengths and how they learn best.
Structured around the IB Units of Inquiry, learning is collaborative, hands-on, and meaningful—encouraging curiosity, teamwork, and real-world connection. Through this holistic approach, students develop the knowledge, skills, and character to grow into confident, globally minded learners, ready for the opportunities and challenges of an interconnected world.
