The area consists of the airspace from about, and including, the Japanese controlled Senkaku Islands (which are known as the Diaoyu Islands in mainland China and are claimed by mainland China as well as Taiwan) north to South Korean-claimed Socotra Rock (known as Suyan Jiao in China).
About half of the area overlaps with a Japanese ADIZ, while also overlapping to a small extent with the South Korean and Taiwanese ADIZ.
