The Site of the World’s First General Anesthesia Surgery
Shunrinken is particularly significant because it was the setting for a groundbreaking achievement in medical history. In 1804, Hanaoka Seishu successfully performed surgery to remove a breast tumor using general anesthesia.
This achievement took place approximately four decades before the widespread development of general anesthesia in Europe and the United States. Seishu’s success is therefore regarded as a remarkable milestone not only in Japanese medicine but also in the history of global surgery.
Inside the facility, visitors can experience dramatic recreations of the historic operation using figures and audio presentations. These displays help convey the atmosphere of the surgery and the challenges faced by doctors at a time when modern anesthetic techniques did not yet exist.
The exhibitions also recreate scenes of Seishu teaching his students and conducting research into anesthetic medicines. Through these displays, visitors can understand how Shunrinken functioned as both a medical institution and a center for medical education.
Shunrinken as a School of Medicine
Shunrinken was not simply a clinic where patients received treatment. It also became an influential school of medicine. After Seishu’s success with general anesthesia surgery became widely known, patients came from many parts of Japan, while aspiring physicians also traveled to Shunrinken to study his surgical techniques.
As the number of students increased, the original facilities became too small. Seishu therefore established larger facilities capable of accommodating many disciples. More than 1,000 students are believed to have studied under him at Shunrinken.
When students who studied at the branch school known as Gasuido in Nakanoshima, Osaka, are included, the total number exceeded 2,000. These students later returned to different parts of Japan and spread the surgical techniques of the Hanaoka School, contributing significantly to the development of medical care throughout the country.
The Life and Philosophy of Hanaoka Seishu
Hanaoka Seishu was born in 1760 in the historical province of Kii, an area that corresponds roughly to present-day Wakayama Prefecture. As a young man, he traveled to Kyoto to continue his studies, where he learned both traditional Chinese medicine and Western medicine introduced to Japan through the Dutch.
Seishu developed his own approach to medicine by combining knowledge from different medical traditions. One of his greatest concerns was how to relieve the suffering of patients. This goal motivated him to devote many years to researching general anesthesia.
Developing his anesthetic, known as Mafutsusan, was extremely difficult. After numerous experiments and setbacks, he eventually developed a formula that enabled him to perform surgery while the patient was unconscious.
The successful operation in 1804 was the culmination of years of research and experimentation. It became one of the most remarkable achievements in the history of surgery and established Seishu’s place as a pioneer of anesthesia.
“Theory and Practice United”
Seishu also promoted the philosophy expressed by the phrase “Naigai Ichigō, Katsubutsu Kyuri”, emphasizing the integration of different medical traditions and the importance of investigating the principles of medicine through practical observation.
Rather than relying solely on established theories, Seishu valued experimentation and evidence obtained through actual medical practice. This approach has strong parallels with the principles of modern medicine and demonstrates how forward-thinking his medical philosophy was for his time.
Highlights of Shunrinken Today
Today, Shunrinken is preserved and opened to the public as a central attraction within Seishu no Sato in Kinokawa City. Visitors can explore the historic main residence and storehouses, which retain elements of Edo-period architecture, as well as reconstructed buildings such as the hospital ward and pharmacy.
One of the highlights is the facility’s immersive exhibition style. Scenes depicting surgery and medical lectures are recreated with figures, sound, and other interpretive displays. Rather than simply viewing historical objects behind glass, visitors can gain a more vivid understanding of how medicine was practiced and taught in the Edo period.
Michi-no-Eki Seishu no Sato
Adjacent to Shunrinken is Michi-no-Eki Seishu no Sato, a roadside station where visitors can combine sightseeing, learning, dining, and shopping.
The complex includes exhibition spaces introducing Hanaoka Seishu’s achievements, as well as restaurants serving dishes made with local ingredients and shops offering regional products.
The central Flower Hill Museum was designed by renowned Japanese architect Kisho Kurokawa. Its distinctive architecture was inspired by the flower of the mandrake plant, which Seishu used in his research into anesthesia.
Inside the museum, visitors can see personal belongings associated with Seishu, historical medical instruments, and valuable documents. These exhibits provide a deeper understanding of his life, medical research, and contribution to surgery.
Local Food and Hands-On Experiences
The roadside station is also a popular place to enjoy local cuisine. Its buffet restaurant uses fresh vegetables and fruit produced in the surrounding area. Kinokawa City is particularly well known as a fruit-growing region, allowing visitors to enjoy seasonal flavors throughout the year.
Nearby, the park and herb garden offer beautiful seasonal flowers and provide pleasant spaces for walking and picnicking. Bicycle rentals and hands-on activities are also available, making the area an enjoyable destination for families as well as individual travelers.
Discovering Kinokawa City’s History and Nature
Kinokawa City, where Shunrinken and Seishu no Sato are located, is blessed with a mild climate and rich natural surroundings. The area offers a combination of historical sites, scenic landscapes, and local food that makes it an appealing destination for travelers interested in discovering a quieter side of Wakayama.
Nearby attractions include Kokawa-dera Temple, a historic Buddhist temple, and Mount Ryumon, a popular destination for enjoying nature and hiking. These attractions can be combined with a visit to Shunrinken to create a well-rounded itinerary.
The area is also accessible from the Kyoto, Osaka, and Kobe region via the Keinawa Expressway, making it a convenient destination for travelers exploring the Kansai region by car.
Visitors can learn about the history of medicine, enjoy the surrounding natural scenery, taste locally produced food, and experience the culture of Wakayama—all in one trip.
A Fascinating Journey into Medical History
Shunrinken and Seishu no Sato offer far more than a conventional sightseeing experience. They provide a rare opportunity to explore the history of Japanese medicine and learn about an achievement that influenced the history of surgery around the world.
The story of Hanaoka Seishu is a story of curiosity, determination, experimentation, and compassion. His desire to reduce the suffering of patients led him to pursue research that was extraordinarily ambitious for his era.
For travelers interested in history, medicine, Japanese culture, architecture, or educational tourism, Shunrinken is a fascinating destination. A visit here offers an opportunity to step into the world of an Edo-period physician and discover how one Japanese doctor helped change the history of surgery.
