Gyosei International Primary School (a.k.a. Morning Star High School) which is located in Yana, Kisarazu, Chiba, Prefecture is an accredited private Japanese Catholic Elementary, Junior and High School. The school is a comprehensive primary and secondary educational system, with 6 years for elementary, 3 for junior high, and 3 for high school. Note that despite its name “international school” it is not an international school according to the Japanese education ministry.  The school however provides a comprehensive education program in three languages (Japanese, English, and French) and is all coeducational. It started from Kudan’s Gyosei Gakuen’s sister school. The main school has two integrated departments, one section conducted predominantly in English, with supplementary French and Japanese instruction, and the other conducted entirely in Japanese.  The school program includes an international course where English is the main medium of instruction in the course. From junior high onwards, students are put into their English classes based on proficiency levels not grade level.

Parallel to the two departments is the Yohane program which is an experimental school where the students study at their own pace and choose their own courses of study. Teachers for this department are employed as counselors for the students, rather than conducting conventional classes. The school also operates a boarding school (see Over 80% of the junior and senior high school Gyosei students live in the dormitories.

  1. The English page is The school has two sections – one that has a curriculum and teaching predominantly in English plus Japanese language and social studies etc. – and there is another section that focuses on Japanese instruction. They prepare students for local entrance examinations as well as SAT prep. So whether your child will be able to study in the US will depend on the SAT testing results and the college’s admissions requirements, interviews, selection process, etc.

  2. I would like to know if any of the teachers who worked at Gyosei International School in Milton Keynes, Buckinghamshire,U.K. are still involved with the school.If so, can anyone give me any information as to their whereabouts. Especially Mr Mukai.

    1. I taught at the international section of the school in Chiba in 1999 and there were certainly still teachers there that had taught in Milton Keynes. I am sure the school in Chiba would be able to help you.
