The Ministry of Posts and Telecommunications (郵政省, Yūsei-shō) was one of the ministries in the Japanese government. It was formed on 1 August 1952 by the merger of the Ministry of Postal Services^[1] (郵政省) and the Ministry of Telecommunications^[2] (電気通信省), which themselves superseded the Ministry of Communications (逓信省, Teishin-shō) from 1 April 1946.

The ministry introduced the POSIVA system for giving aid to foreign countries in January 1991.^[3]

In January 2001, the ministry was merged with other ministries to form the Ministry of Internal Affairs and Communications. The Postal Services Agency, under the new ministry, continued the POSIVA program.^[3]
