DSN Corporation Japanese: 株式会社ディー・エス・エヌ is a corporation owned by SKY Perfect JSAT Group, NEC and NTT Com. It was founded on December 19, 2012 for the sole purpose of acting as an investment vehicle in the private finance initiative that would handle the Japanese military X band DSN satellite network from 2015 to 2031.

SKY Perfect JSAT Group (JSAT) along NEC, NTT Com and Maeda Corporation formed a joint venture called DSN Corporation. On January 15, 2013, DSN Corporation announced that it had closed a contract with the Ministry of Defense to execute the "Program to Upgrade and Operate X-Band Satellite Communications Functions, etc". The contract is a private finance initiative, where private funds, management and technical capabilities are used to upgrade and operate the Japanese military X band DSN satellite network.

Based on this program, DSN Corporation will manufacture and launch two satellites plus perform the necessary upgrades to ground control stations. It will also operate, manage and maintain the facilities and equipment through fiscal years 2015 to 2030. The total program cost was estimated at ¥122,074,026,613.

The second satellite was expected to launch in January 2017, starting operations on March 2017. The program and the operations of the second satellite were expected by March 2031.
