The school opened in April 2016 as Bilingual Preschool Cosmo Global Kids Bashamichi, Yokohama, starting with 3 two-year-old children. In July 2016 the Contact Book app was introduced to share photos and activities with parents, and by September 2016 an additional school bus was added; in January 2017 two optional preschool classes began. In April 2020 the school changed its name to Cosmo Global Kids International School and opened Afterschool for elementary students. In April 2023 Kannai Campus expanded and relocated to 2-25-2 Minaminakadori, creating a two-campus system with Bashamichi and Kannai and expanding from 5 to 12 classes. CGK was authorized as an IB World School to deliver the Primary Years Programme in July 2024 and became an IB MYP candidate school in 2025, with a high school scheduled to open in April 2028.
Since opening in 2016, CGK International School has grown into a community of students, families, teachers, and partners dedicated to high‑quality care and education. The CGK Community partners with local businesses and organizations to offer hands‑on experiences and mutual development, including Park Day, Italian Restaurant Visit, and numerous collaborative activities. The community organizes events and programs such as the School Festival, IB Info Sessions, Saturday School, and donation campaigns, with active involvement from CGK Student's Families and International Families. English and Japanese LINE channels connect families to CGK updates and opportunities for involvement.
There is no formal PTA at CGK; parent involvement is organized through the CGK Community framework. Parent groups include CGK Student's Families and International Families, which coordinate family engagement and collaboration with local businesses and organizations. Families participate in events such as School Festival, Park Day, Italian Restaurant Visit, Parents' Social, Social Night, and IB Info Sessions. Parents contribute through special lessons by parents, field trips to partner companies and shops, and seminars/workshops, coordinated with CGK's community team. Communication with families is facilitated by LINE official accounts in English and Japanese, and public events and community initiatives are listed on the CGK Community page, with networks like Yokohama International Family supporting broader engagement.
