One World International School provides K-12 education across eight global campuses, including multiple locations in Japan.

With small class sizes and a supportive learning environment, students build strong academic foundations while developing creativity, character, and a global outlook. Learning is hands-on and purposeful, encouraging curiosity, critical thinking, and real-world connection across the curriculum. Our diverse community and dedicated educators help every child grow in confidence, form meaningful relationships, and thrive as an active learner, at school, and beyond.

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.

As part of our ongoing commitment to providing a well-rounded, holistic education, our After-School, Clubs, and Extracurricular (ACE) programmes support students’ social, physical, and emotional development in a fun, international, and inclusive environment. Led by professional coaches and experienced instructors, our clubs give students the chance to explore interests, build confidence, and form strong friendships beyond the classroom.
Students can choose from a wide range of activities—from competitive sports such as soccer, volleyball, and basketball, to creative and performing arts like hip-hop dance and pottery, as well as enrichment options including chess and Intensive English. We also offer Afterschool Care for families who need a safe, supportive space for children to unwind, play, and learn after the school day ends.

OWIS Osaka’s purpose-built campus is designed for inquiry-led learning, creativity, and student wellbeing across Early Childhood, Primary, and Secondary.
