J.K. Rowling, author of the fantasy series “Harry Potter,” has let muggles in on a big secret — there is a hidden magic school in Japan.

Rowling revealed the Japanese version of Hogwarts on her Pottermore website Friday, along with schools in North America, Brazil and Africa. In the “Harry Potter” universe, there are now 11 institutions worldwide where young wizards and witches secretly learn how to use magic.

The Japanese school, named Mahoutokoro (Place of Magic), is described as situated on the highest point of the volcanic island of Minami Iwo Jima, or Minami Iwoto, as it is known in Japan. According to Rowling’s essay, Mahoutokoro is famous for its academic prowess and strong record in Quidditch, a sport in which players must fly on broomsticks and dodge flying balls.
