Parent Experience

Community, involvement and what it's like to be a parent at this school

History

Yokohama International School opened on October 27, 1924, in a rented YMCA classroom with six students and one teacher, in the wake of the Great Kanto Earthquake. As enrollment grew, the school added facilities including a boarding house and by 1939 had over 100 students from 21 nationalities. World War II interrupted operations; the school closed in 1941 and its buildings were repurposed as a refugee center, with the original campus destroyed by fire in 1945. It was rebuilt in Yamate and reopened on September 15, 1955, and YIS was officially registered as a School Juridical Person in 1969. The IB Diploma Programme was introduced in 1986, YIS earned dual accreditation from ECIS and NEASC in 1991, and in January 2022 moved to a purpose-built campus in Honmoku, with the centenary celebrated on October 27, 2024.

Community

YIS serves an international community with students from more than 49 nationalities and staff from more than 21 countries. The Japanese Culture Program provides intercultural learning across the IB framework with hands-on experiences in arts, drama, printmaking, and local cultural activities. Community life is reflected in In Our Words, which shares classroom innovations, cultural events, and service projects. Dragon Dining and The Street Café create daily social hubs on campus, offering diverse meals, allergen labeling, and opportunities for parents and students to connect.

Parent-Teacher Association

The YIS Parent Hub hosts the PTSA, the Parent Teacher Student Association. The PTSA organizes events to connect families throughout the year, including cultural celebrations and casual coffee mornings. Past activities are highlighted on Instagram under

yisptsa, and volunteers are invited to help plan events. Annual Food Fair, organized by the PTSA, is a long-running multi-cultural festival and major fundraising event. The PTSA maintains a leadership team for 2025–2026 with roles such as President, Vice President, and Events Coordinator, and supports additional activities through a dedicated Parent Activities program.
