Admissions

Admissions
Admissions Process (4-step).

1. Initial contact and campus visit. Reach out to the Osaka admissions counsellor, who will be your assistant and guide through the rest of the process. Tell them you would like a tour of the campus and set a convenient date. The counsellor provides information about OWIS Osaka's programmes and what to expect during the visit, and can advise on next steps. For relocations within Japan or from afar, the counsellor can share a relocation guide and discuss timelines (research typically 6–12 months in advance for city-to-city moves).

2. Application review and fee instructions. After you visit, the admissions counsellor reviews the application form and directs you on how to pay the online application fee. They walk you through any required documents and answer questions about program placement and entry requirements. This step ensures you understand what is needed before proceeding with the formal application.

3. On-site logistics and resources. Return to the school to meet Student Services, who will provide uniforms, photo IDs, and school resources. They can also arrange lunches and school bus services if needed. This step covers practical arrangements to support a smooth first weeks after enrollment.

4. Financing and enrollment confirmation. Meet with the finance department to pay for the first term tuition fees. Once the payment is completed, the child is ready to start school. If the application has been accepted, OWIS Osaka welcomes the child into the school community and confirms enrollment details.

Language of instruction and English support (context for admissions). OWIS Osaka uses English as the language of instruction for core subjects. English language support pathways are available, including Academic English Preparation (AEP), a four-month transition programme, and After-School Intensive English clubs to support learners at different stages of language development.

Relocation and ongoing inquiries. The admissions team can assist with transfers between OWIS campuses and between schools, and there is a relocation guide for moving between cities or countries within Japan. Rolling admissions are available year-round, with August (start of the academic year) and the December or April terms highlighted as advantageous entry points when possible.
