J.K. Rowling has recently added some new interesting information on her website "Pottermore".
Most people are aware of Hogwarts School of Witchcraft and Wizardry. Harry Potter fans would know of Beauxbatons Academy of Magic and Durmstrang Institute. These are the only schools in the wizarding world but now there are others.
The names of the new schools are Mahoutokoro, Ilvermorny, Uagadou, Castelobruxo. J.K. Rowling has not yet released information on Ilvermorny.
Castelobruxo is The Brazilian school of magic that can be found hidden deep in the rainforest. The school takes all the students from all over South America. The school resembles a beautiful temple but Muggles see it as a ruin (like Hogwarts). The students wear bright green robes as uniforms. The students often are advanced in Herbology and Magizoology.
Mahoutokoro is the Japanese Wizarding School. The school takes children from age seven but does not board them until age eleven. The school is an exquisite palace made of mutton-fade jade set on top of an "inhabited" volcano. The robes the students wear change colour once their levels of learning rise. The robes start off faint pink but once they are at the end of their magical education the robes turn to gold. If the students robes turn white it means that they have broken the Japanese Wizards' Code which resembles what the Europeans call "Dark Magic". The school is known for having some of the best Quidditch players the magical world has ever seen.
Uagadou is located in Africa and is the only major African wizarding school. The school also happens to be the largest wizarding school in the world because it does not only welcome students from Africa but from several other continents. The stunning school is carved in a mountainside and it is even hard for wizards to find due to the fact that it is shrouded in mist. The school is known for being well versed in Astronomy, Alchemy and Self-Transfiguration.
On Pottermore it says that they're are 11 major magical schools in the Harry Potter wizarding world meaning that we will probably get more information on these schools.
