Pregnancy Dolls of Edo: Curiosity, Education, and Spectacle

In the bustling streets of Edo (present-day Tokyo) during the 18th and 19th centuries, entertainment took many forms, from kabuki theatre to sumo wrestling. Among the more unusual attractions were the misemono, or sideshow carnivals, which catered to the city’s ever-curious residents. These temporary exhibitions featured a wide array of spectacles, blending education with entertainment in a way that was both engaging and, at times, deeply bizarre. Among the many attractions designed to evoke wonder and curiosity, one of the most intriguing was the Pregnancy Dolls—a mechanical or anatomical model that revealed the stages of foetal development inside the human womb.

The Appeal of Misemono Exhibitions

Misemono were a distinctive feature of Edo-period urban culture. They were transient affairs, setting up in bustling areas like Asakusa and Nihonbashi, and showcased everything from exotic animals and performing artists to oddities of nature and mechanical automata. While many exhibits catered to the public’s love for the strange and grotesque, others had an educational purpose, demonstrating new discoveries in science, medicine, and natural history.

One of the most fascinating attractions within these exhibitions was the pregnant doll. Records from 1864 describe a particularly popular show in Asakusa that focused on educating audiences about the human body. A pregnant doll was displayed whose abdomen could be opened, revealing a series of meticulously crafted foetal models representing various stages of prenatal development. This feature captivated audiences, offering them a rare glimpse into the hidden world of human gestation.

The Role of Foetal Models in 19th-Century Japan

While it is commonly believed that these dolls were primarily created as training tools for midwives, the reality is more complex. The Edo period saw significant developments in obstetric knowledge, much of it influenced by Dutch medicine (Rangaku), which introduced anatomical studies previously unavailable in Japan. Medical practitioners sought ways to improve midwifery education, and anatomical models provided an invaluable teaching aid.

However, the presence of these foetal models in sideshow carnivals suggests that they also held a strong entertainment value. The spectacle of a mechanical doll that could "give birth" was not just a medical teaching tool but a marvel in its own right, blending curiosity, performance, and emerging scientific knowledge. The fine craftsmanship and anatomical precision of these models were impressive, and they undoubtedly fueled public fascination with the mysteries of life and reproduction.

Japan’s First National Industrial Exhibition and the Work of Motoyoshi Hasegawa

By the late 19th century, Japan was undergoing rapid modernisation under the Meiji government. The 1877 First National Industrial Exhibition, held in Ueno, Tokyo, was a major event designed to showcase the nation’s industrial, artistic, and scientific advancements. Among the exhibitors was a physician from Yamagata Prefecture named Motoyoshi Hasegawa, who presented an elaborate set of foetal models demonstrating seven different stages of human gestation, from embryo to full-term infant.

The models displayed at this exhibition were a refined version of what had previously been seen in misemono carnivals, but they continued to captivate audiences. The attention they received suggests that, despite the increasing focus on scientific progress, the public’s fascination with the human body and its hidden processes remained as strong as ever.

Today, these early foetal models are preserved at the Edo-Tokyo Museum, offering insight into the intersection of entertainment, education, and science in 19th-century Japan. They serve as a reminder of a time when learning about the human body was not confined to medical schools but was part of a broader cultural curiosity that extended into public entertainment.

While the pregnant dolls were initially displayed in lively street fairs alongside acrobats and exotic creatures, they also played a role in shaping Japan’s medical education. Their presence in both settings highlights the blurred lines between spectacle and instruction in Edo and Meiji-period Japan. Whether in a carnival tent or an exhibition hall, these models captured the imaginations of those who encountered them, leaving a legacy that continues to intrigue historians and scholars today.
