At Shinagawa International School (SIS), we strive to deliver a Japanese curriculum that supports and challenges students of all levels of ability by differentiating our lesson activities and individualizing the tasks. Accordingly, we offer two Japanese language learning program: the Kokugo Program, for students who are proficient speakers of Japanese, and the JAL (Japanese as an Additional Language) program. The Kokugo program students follow the national curriculum and learning objectives that are utilized in Japanese public schools, however, is a modified version due to English being our main language of instruction.

The instruction for JAL (Japanese as an Additional Language) students is flexible. JAL kids are provided with a different program to help them learn the daily language and basic Japanese skills. They will also link to the Programme of Inquiry (PYP) during their lessons to consolidate the learning they are doing in their homeroom classes.
Japanese specialists are well-knowledged in the latest policies, research, and the methodologies of the national curriculum and differentiation of language learner. They have been involved in professional development workshops and conferences for Japanese instructors of International Schools in Japan.
