The Tohoku University Library in Japan has an online display of the painfully real Kaibo Zonshinzu anatomy scrolls, painted in 1819 by Kyoto-area physician Yasukazu Minagaki. The style is markedly different to the Western anatomy drawings, showing blood and gore, and often faces of convicts status post decapitation.
