An extracurricular group called Japanese Culture is offered.

Japanese as Foreign Language (JFL) classes teach vocabulary and phrases through activities, songs, etc.

In Japanese as Native Language (JNL) classes, students learn Kokugo using textbooks and programs identical to those used by public elementary schools.

The curriculum at Yoyogi International School integrates philosophies and goals from established education programs to prepare children for higher education across the globe:

• The Learner Profile attributes of the International Baccalaureate’s Primary Years Programme (IB PYP)
• UK National Curriculum Key Stage 1, Key Stage 2, and the Early Year Foundation Stage
• US Common Core State Standards
• US State Guidelines (New York and Massachusetts Board of Education)
• National Education Technology Standards from the International Society for Technology (IT Curriculum only)

Guided by the belief that students learn best when independent and engaged learning is encouraged, students learn by doing, exploring the limits of their curiosity, teaching each other, and having fun. The school educates the whole child and emphasizes the development of positive attitudes toward learning in small class sizes.

The school uses tools such as White Rose Maths and IXL. Mathematics is taught within the context of everyday life using the Everyday Mathematics program.

The primary division uses Macbook Air and applications such as Google Suite for Education, Garageband, and iMovie to prepare presentations and nurture creativity.

Extracurricular activities include Junior Scientist (Yoyogi campus) and STEM (Tomigaya campus)

The school is located next to one of the biggest parks in the city, a large multi-use sports field, and the National Olympics Memorial Youth Center
