International School Summer Programs in Japan: A Parent's Guide (2026)

For many families in Japan, summer is when kids first step inside an international school. Summer programs are shorter, non-committal, and often the fastest way to see whether the culture fits — but the good ones book months in advance.

Summer camps let families sample international school culture without a full-year commitment

Why Summer Programs Matter

• Try before you commit. A 2–4 week camp reveals whether your child thrives in an English-medium environment.
• Maintain English over summer. Especially important for bilingual or returnee children.
• Get on the school's radar. Not a guaranteed admissions path, but it's a legitimate way to meet staff.
• Fill the long Japanese summer break. Public school breaks (mid-July to late August) align well with camp windows.

Always confirm current dates, ages, and fees on the official school website — camps change annually.

Tokyo Summer Options

ASIJ Summer Day Camp: In 2026, its 52nd season, it ran at ASIJ's Chofu campus for Grades 1–6 and in Roppongi, in four five-day sessions between July 20 and August 14, from 9:30am to 3:30pm. The fee for children not enrolled at ASIJ at Chofu was about ¥126,000 a session. Check sdc.asij.ac.jp for 2027.

BST summer camps: The British School in Tokyo runs age-banded camps that reflect the British calendar and instruction style.

Tokyo International School (TIS) summer: IB-influenced enrichment activities.

Nishimachi: Programs when offered emphasize bilingual balance.

Kobe & Kansai Summer Options

Canadian Academy (Rokko Island): In 2026 CA ran a parent-and-child residential week, June 21–27, for children aged 4 to 12, staying in the school's residence; parents observed IB classes and joined workshops. It cost ¥200,000 for one parent and one child, or ¥300,000 with two children, and was open to residents of Japan only. Check CA's summer page for 2027.

Marist Brothers summer activities: Vary year to year; check with admissions.

St. Michael's summer offerings: Confirm with the school directly.

Osaka schools (OISKG, Senri, Osaka YMCA): Smaller summer components; often more academic than camp-style.

Preschool-Age Summer Programs

Younger children (roughly ages 2–6) need a different environment from primary-school camps.

Kobe (Rokko Island): Peter Pan International Preschool runs summer programs alongside its regular classes, which let your child try full days in English before you commit to a year. Canadian Academy's official site mentions its long relationship with Peter Pan.

Disclaimer: Attending Peter Pan (or any preschool camp) does not guarantee admission to Canadian Academy or any other school.

Tokyo preschool summer options vary by ward — most bilingual and international preschools run mini-summer programs, though seats are limited.

How Families Use Summer Strategically

1. Testing school fit before applying for a place mid-year
2. Bridging a mid-year international move with a familiar English environment
3. Preventing "English attrition" for bilingual children in Japanese hoikuen
4. Preparing for a September start at an international school by exposing kids to the routine
5. Returnee families using summer to reintroduce Japanese peers before school year

Timing and Booking

Rule of thumb: For popular Tokyo and Kobe programs (ASIJ's day camp, Canadian Academy's summer week, Peter Pan's summer sessions), inquire by February for the same summer.
