I have been told that this is a special issue
devoted to "Science inJapan." Since science
pursues truth and scientific technology puts
truth to the use of mankind, it is desirable
that such studies be pursued through cooperation that transcends national and other
boundaries. I am pleased to note that, in
recent years, when I visit research institutes
inJapan, I often come across foreign researchers. Through my own study of ichthyology, I
have come to feel strongly the importance of
international cooperation in conducting scientific studies. I recall with a sense of gratitude that behind each one of the papers I
have published there has been the unsparing
cooperation of people abroad. I shall be delighted if this issue "Science in Japan" deepens the understanding of scientific activities
here and contributes to the further promotion of international exchange.
When one thinks of the development of
science in Japan, one recalls the untiring efforts ofthe people who nurtured its growth in
ages past when communication with foreign
countries was limited. I am not a student of
the history of sciences, but as a person interested in this field, and on the occasion ofthis
special issue, I would like to acknowledge some
of these early cultivators of science in Japan.
Japan had been learning from Chinese
civilization from olden times, but it was only
in the latter half of the 16th century that the
country came in contact with European science. It is said that in 1543 Tanegashima, an
island in the south of Japan, was visited by
Portuguese who introduced firearms to the
inhabitants. Within only a few years, several
dozen guns had been manufactured on the
island, and the techniques for their manufacture had begun to spread throughout Japan.
In the meantime, the Portuguese returned
home with stories about Japan, and thereafter
Portuguese ships loaded with merchandise for
trade appeared frequently in Japanese ports.
After 1549, Francis Xavier and many other
Jesuits came to Japan, serving both as missionaries and as conduits of European learning. It was during this period, for example,
that the Japanese first learned that the earth
was round and were first exposed to European medical practices, including surgery,
which was not part of Chinese medicine.
However, the Copernican theory, which had
been formulated in the same year as the first

over 200 years, until the arrival of an American fleet in 1853 and the subsequent signing
of the Treaty of Peace and Amity between
the United States and Japan.
During the period of Japan's national seclusion, Europe produced many eminent
scholars, such as Newton, Lavoisier, and
Linnaeus, and saw great scientific progress;
meanwhile, in Japan, due to the severe restriction of exchange with Europe, European
learning waned year by year. Engelbert
Kaempfer, who stayed in Japan from 1690 to
1692 as a physician of the Dutch trade office,
gathered an astonishing amount of information about the country and later published a
book entitled History ofJapan. Notably, the
book contains no accounts of exchanges with
Japanese scholars, except for one reference to a
physician of the shogun who sought medical
advice during one ofhis two visits to Edo in the
company ofthe chief ofthe Dutch trade office.
However, in 1716, when Tokugawa Yoshimune assumed power as the eighth shogun,
the domestic situation began to change.
Yoshimune tried to absorb knowledge of European civilization from the chiefof the Dutch
trade office when he traveled to Edo. He also
placed orders for books and various goods
from Europe and encouraged the study of the
Dutch language. When he embarked on calendar reform, he received a suggestion that
the new calendar should not be based on
Chinese calendar theory, which had many
errors, but should be based on European theory.
Yoshimune subsequently authorized the importation ofChinese translations of European
scientific books that were unrelated to Christianity. The government had long maintained
a policy of minimizing contacts between Japanese and foreigners, but from this period onward, a willingness to learn from advanced
European science began to appear.
There were changes in the field of medicine, too. Some physicians who had been
trained in Chinese medicine began to question its validity, turning instead to the concept of trial and experimentation and showing great interest in the accurate anatomical
drawings in Dutch medical books. Among
such physicians was Yamawaki Toyo, a court
physician in Kyoto. He observed the first
officially approved dissection of the human
body and, for the first time in Japan, published in 1759 the record of the dissection in
several anatomical illustrations under the title
of Zoshi (Record of Internal Organs). However, because virtually no physicians in those
days could read Dutch books (with the exception of some interpreters in Nagasaki who
studied medicine under Dutch physicians),
they had to satisfy themselves with looking
at the illustrations.
It was during this period that Ontleedkundige Tafelen (Anatomical Tables), written originally in German by Johan Adam Kulmus in
1734, was translated from Dutch into Japa-

Dutch and Chinese ships in Nagasaki Harbor, 17th century. During the period of national
seclusion, only the Dutch and Chinese, who had come to Japan solely for trading purposes, were
allowed to stay. The Dutch were confined to a small man-made island off Nagasaki, called Dejima,
where they maintained a trade office.

Kyoto, while supporting himself as a secondhand copper-ironmonger and as a masseuracupuncturist, and that he had no particular
teacher. Although he could not read Dutch,
he referred to Dutch medical books and also
read Chinese medical books. However,
Gen'etsu attached utmost importance to what
he observed with his own eyes and touched
with his own hands. One of his major contributions was the development of a new method
for delivering a deceased fetus with an iron
hook when the mother's life was in danger.
With Gen'etsu's method it became possible for
the first time to save the mother's life.
Gen'etsu published his work, Sanron
(Theory of Obstetrics), in 1765. In this book
he described his own finding that a child in
the mother's womb is normally positioned
head downward. In A New Book of Anatomy,
which was published nearly 10 years after the
publication of Theory of Obstetrics, Genpaku
commented that he had doubted Gen'etsu's
theory because it was different from the traditional view and because he could not find
corroboration in various Dutch books of
anatomy. Genpaku later had occasion to look
at an English book on obstetrics whose drawings confirmed Gen'etsu's theory. Realizing his
mistake, Genpaku praised Gen'etsu's achievement, admitting that he had been wrong to
doubt the theory and expressing regret that he
had doubted so easily something that he had
never seen and had been unable to verify.
