Principal Ms. Prerna Mannan said:
“We are so proud of our students for their remarkable IGCSE results! Their determination and resilience have truly paid off, and this success is a wonderful reflection of the support from teachers and parents. Congratulations to our learners. This achievement is just the beginning of many more milestones to come.”


Mr. Thomas Marsilin, the Cambridge Coordinator at GIIS Tokyo, and his team of dedicated, experienced educators played an important role in this success. The results of the 2025 cohort reflect the structure of GIIS Tokyo’s Cambridge Lower Secondary Programme (CLSP) and IGCSE programmes, which together provide students with a clear and progressive academic pathway. The CLSP builds essential skills in inquiry, problem-solving, and subject knowledge, which form the foundation for success at the IGCSE level. In turn, the IGCSE equips students with internationally recognised qualifications and prepares them for advanced programmes such as the IB Diploma or A Levels, as well as university studies worldwide. These results demonstrate the school’s ongoing focus on ensuring students are well-prepared for future academic pathways in a global context.


We extend our congratulations to all students for their achievements, and to the educators whose guidance and commitment supported them throughout this journey.


Warm Regards
