Why it is in this guide
An older-child option for intercultural learning and leadership in Japan, with 2027 dates and fees already announced.
Who it may suit
Curious 13–14-year-olds ready to discuss ideas in English and live with peers from different backgrounds for two weeks.
What to weigh up
Ages 7–10 are outside the advertised range. The official age and birth-month criteria conflict at the boundary. Personal devices are held for the stay, and parents cannot visit school buildings.
Operating history and evidence
The official 2027 page supports dates, fees, English and international access. Contradictions remain in the age/birth window, refund years and an old application reference; those details need correction.
Before you book
The July 2012–June 2014 window includes some 15-year-olds despite the stated 13–14 age range. Refund years also conflict. Confirm the exact birthday before applying and obtain corrected refund terms before payment.
Cancellation and refunds
Operator cancellation refunds tuition. Student cancellation text permits refunds through 25 April 2027, but the next sentence says no refunds after 25 April 2026. This inconsistency leaves the operative 2027 cutoff unverified.
