Itachiyama Institute (Japanese: 井闥山 (いたちやま) 学院 (がくいん) Itachiyama Gakuin) is a private high school in Tokyo. The school has a lot of athletic clubs along with a foreign exchange program[1].


In the manga, the Itachiyama volleyball tracksuit uniform consists of a yellow and green tracksuit, with 'Itachiyama' written on the back. The volleyball uniform itself consists of yellow shorts and a jersey with a yellow-green gradient on the upper half, a black stripe in the middle, and white on the bottom. The shirts have 'Itachiyama' written on the back alongside their number in black. Their practicing clothing consists of a yellow shirt and green shorts.

In the anime, Kuroo tells Lev and Hinata about the top three aces with Sakusa shown to be one of the aces. He's shown wearing a lilac jacket with the school name written in the back of it in white letters. The color scheme is later corrected in the anime to match that of the manga.
