The stamps were heralded as about to be issued in time for the festival of the Shrine celebrated at Taipeh on October 27 and 28, 1901. In 1905, as the outcome of Japanese military successes in the East against China and Russia, full administrative control was taken over Corea, and a special stamp of the value 3 sen was issued to mark the amalgamation of the Japanese and Corean postal services.
