About the JOTRC Airspace

The Joint Okinawa Training Range Complex (JOTRC) consists of open ocean, offshore , and onshore areas geographically situated on and around the island of Okinawa. 

JOTRC users include USFJ and JSDF units stationed in Okinawa, visiting units from mainland Japan, and transit units. The goal of the JOTRC is to support training and operational requirements for military stakeholders, accommodate training needs (when mission requirements permit), maintenance check flights and aerial surveying needs of the civil flying community.

The Joint Okinawa Scheduling Cell (JOSC) serves as the U.S. Forces Japan representative for airspace management and scheduling of JOTRC training areas. The JOSC serves as the DoD/MoD focal point and central clearinghouse for all Special Use Airspace (SUA) / Warning Area matters that pertain to any DoD/MoD airspace-related activity within the AOR. The JOSC maintains a SharePoint site for DoD CAC users. The JOSC utilizes the Digital Collection and Scheduling Tool (DCAST) as the primary method for scheduling sea, air and land space within the confines of JOTRC. A DCAST account login can be requested at the following website:
