The Tokyo Metropolitan board of education said Thursday that an expensive cram school for elite students that critics say will create inequalities in education can open at a public junior high school in Suginami Ward.

The one-year school, called Yoru Supe (Night Special), is generating controversy for targeting top-level students at Wada Junior High School who want to ace their high school entrance exams.

Chiiki Honbu (Local Headquarters), a volunteer group of about 100 aspiring teachers and parents whose children graduated from Wada Junior High, will run the school, which will offer math and Japanese on Monday, Wednesday and Friday nights and English on Saturday afternoons on Wada's campus.
