The Gyosei International School (暁星国際学園, Gyōsei Kokusai Gakuen) is a school located in Yana, Kisarazu City, Chiba Prefecture, Japan. The principal is Shigeru Tagawa (田川 茂 Tagawa Shigeru). As of 1995, it was a Roman Catholic institution, and Tagawa was a member of the clergy.

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 is a complete primary and secondary educational system, with six years for elementary, three for junior high, and three for high school.

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.
