Japanese missions to Sui China
Japanese missions to Sui China represent a lens for examining and evaluating the relationship between the Sui dynasty and Japan in the 7th century. The nature of these bilateral contacts evolved gradually from political and ceremonial acknowledgment to cultural exchanges; and the process accompanied the growing commercial ties which developed over time. Between 607 and 838, Japan sent 19 missions to China. Knowledge was the principal objective of each expedition. For example: Priests studied Chinese Buddhism. Officials studied Chinese government. Doctors studied Chinese medicine. Painters studied Chinese painting. Approximately one third of those who embarked from Japan did not survive to return home. See also
