The OWIS Tsukuba Team

Certified. Experienced. International.

All teachers at OWIS Osaka hold recognised degrees or teaching qualifications from established education institutions and bring prior classroom experience to our school. This ensures they are well equipped to inspire positive behaviour, build strong relationships, and deliver engaging, accredited learning that helps every student thrive.

We carefully select educators who are dynamic, caring, and internationally minded, with a commitment to lifelong learning and globally recognised values such as respect, kindness, and integrity.

Our teachers are supported by dedicated teaching assistants who help students succeed across all grade levels. In addition, a full-time qualified nurse is on campus to provide medical care, while our guidance counsellors support students’ personal, emotional, and future pathway development whenever needed.
