School Events

Kokusai High School has two big events, Sports Day and OYO-Festival in which our students actively participate.

Sports Day

Sports Day is held every May after Golden Week at our school field. Students are divided into three teams of Red, White and Blue and compete against each other through the Endan (musical cheering dance performance) and other athletic competitions.

OYO-Festival (school culture festival)

Our school festival is held over a weekend in mid-September every year.
Each class and members of the school’s various extracurricular activity clubs, the school committee, and other volunteers plan a wide range of programs. Students start preparing for this festival from the middle of May and spend most of the summer making the festival a success. Please come and enjoy the biggest event of Kokusai High School.
