A Nagoya citizens' group has found a telegram that Emperor Showa sent in 1934 to Puyi while he was emperor of the Japanese puppet state of Manchukuo.

Copies of telegrams sent by Emperor Showa, who was known as Hirohito during his lifetime, are stored at the Imperial Household Agency and other public institutions. It is rare for an original to be found elsewhere, a government official said.

The telegram owned by a museum in Jilin, China, was sent May 3, 1934, in response to one from Puyi expressing thanks for the hospitable reception given to his envoy by the Japanese government.

The telegram said, "I am glad that the two countries -- Japan and Manchuria -- have intensified our relationship." It ended with "Hirohito."

The group said it plans to borrow the "precious document showing Imperial diplomacy" from the museum and exhibit it in Nagoya this summer.

Puyi, the last emperor of the Qing Dynasty of China, was installed as the regent following the conquest of Manchuria by the Imperial Japanese Army, and became emperor of Manchukuo in March 1934. Emperor Showa died in January 1989.
