Curriculum

A preschool for 15 months to 5 years, founded in 1998. It became an IB (International Baccalaureate) World School in 2017 and has brought the PYP (Primary Years Programme) framework into its original inquiry-based curriculum. Classes are split into the English Regular Program and the English–Japanese Dual Immersion. The Regular Program runs Monday–Friday in English, with daily Japanese lessons of 10–30 minutes depending on age. It has 4 classes, Kaze (15 months–2 years), Yuki (ages 2–3), Tsuki (ages 3–4) and Hana (ages 4–5), and besides 5 days a week, you can choose 3 days a week (Monday, Wednesday, Friday) or 2 days a week (Tuesday, Thursday) (Hana is 5 or 3 days a week). Dual Immersion began in 2002; Yama (ages 2–3) has half of each day in English and half in Japanese, and the ages 3–5 classes have half the week in English and half in Japanese. Each class has two homeroom teachers, native speakers of Japanese and English. Yama is 2, 3 or 5 days a week, and the ages 3–5 classes are 5 days a week. There is park play time every day. Care hours are 8:15–14:00 for Full Day and 8:15–12:30 for Half Day (Kaze only). After school, the English Sora Class runs from 14:00 to 18:00; pick-up can be at any time, and fees are hourly. There are also after-school classes such as ballet, drama, STEAM, Chinese, Japanese, music and violin (vary by term).
