Here is a selection of old anatomical illustrations that provide a unique perspective on the evolution of medical knowledge in Japan during the Edo period (1603-1868).



Pregnancy illustrations, circa 1860

These pregnancy illustrations are from a copy of Ishinhō, the oldest existing medical book in Japan. Originally written by Yasuyori Tanba in 982 A.D., the 30-volume work describes a variety of diseases and their treatment. Much of the knowledge presented in the book originated from China. The illustrations shown here are from a copy of the book that dates to about 1860.

Anatomical illustrations, late 17th century [+]

These illustrations are from a late 17th-century document based on the work of Majima Seigan, a 14th-century monk-turned-doctor. According to legend, Seigan had a powerful dream one night that the Buddha would bless him with knowledge to heal eye diseases. The following morning, next to a Buddha statue at the temple, Seigan found a mysterious book packed with medical information. The book allegedly enabled Seigan to become a great eye doctor, and his work contributed greatly to the development of ophthalmology in Japan in the 16th and 17th centuries.

Japan's first recorded human dissection, 1754

These illustrations are from a 1754 edition of a book entitled Zōzu, which documented the first human dissection in Japan, performed by Tōyō Yamawaki in 1750. Although human dissection had previously been prohibited in Japan, authorities granted Yamawaki permission to cut up the body of an executed criminal in the name of science.

The actual carving was done by a hired assistant, as it was still considered taboo for certain classes of people to handle human remains.

Japan's second human dissection, 1758 // First human female dissection, 1759

In 1758, a student of Tōyō Yamawaki's named Kōan Kuriyama performed Japan's second human dissection (see illustration on left). The following year, Kuriyama produced a written record of Japan's first dissection of a human female (see illustration on right). In addition to providing Japan with its first real peek at the female anatomy, this dissection was the first in which the carving was performed by a doctor. In previous dissections, the cutting work was done by hired assistants due to taboos associated with handling human remains.
