Hayashi Razan
The Tokugawa Shogun had the Southern Ming, Zheng Zhilong and Koxinga's official requests for Japanese military intervention compiled by Hayashi Razan. The Japanese viewed the Manchus as "barbarians", calling them "upstarts from a small territory known even there as the land of the northern barbarians" which was the view of most Japanese, and the book "Metamorphosis from civilized to barbarian" 華夷變態 was written about the Qing conquest by Hayashi Gaho, son of Hayashi Razan.
