Skills & Values Nurtured at OWIS Tsukuba

At our Japan International School, we want our students to develop important values and real-world skills that can help them excel in school and beyond.


Through activities and academic lessons that we teach at the school, we aim to strengthen our students’ communication skills to enable them to have an improved ability to interact with the world around them.


We organise group activities that facilitate communication and collaboration among our students, who belong to different cultural backgrounds. This, in turn, promotes camaraderie that goes beyond cultural boundaries.


Our students take an active part in community service projects, which teach them empathy and compassion and help them evolve as responsible citizens in the future.

Critical Thinking

Our students are encouraged to play, explore and discover things on their own in their surrounding environment, which helps improve their critical thinking skills.
