Science and Technology Chronology of Japan before 1720
Two points are on order to those students who assume “Eastern” research projects following completion of “Western” ones, falsely thinking that the transition is seamless, which is my fault. First, Europeans and East Asians studied nature for different outcomes. In Europe natural knowledge was studied as a ‘phenomenon,’ whereas in East Asia it was studied as a ‘portent’; important difference. For example, Sino-Korean-Japanese astronomy was calendrical. There was no observational astronomy independent of the astrological and calendrical arts. Natural knowledge was part of the paraphernalia of dynastic legitimacy, and its revisions a confirmation of the mandate of heaven. The same situation applied to eclipses, medicine, health, and earth quakes; all were studied to understand the effect on an emperor, not for their own sake.
Second, unlike on the other chronologies that end at 1600, the interface to modern science, the chronology for Japan goes up to 1720, when it finally rescinded the ban on Western books, for the first time Western knowledge on an advanced and professionally useful level was transmitted and had a decisive influence on the course of Japanese history. (Though, before the early nineteenth century, the impact of Western learning on Japan was nevertheless negligible.) A corresponding date for the Asian continent is on order.
Third, some books overly exaggerate the influence of Western books and of Westerners on Japan 1543-1854, and some wrongly apply the Chinese context to Japan. Prior to the mid-nineteenth century, the historical record suggests little or nothing in the way of impact. Japanese understanding of was on the whole quite shallow and was quickly forgotten after isolation edicts were enacted in 1639, one hundred years after encounters with foreigners. The tributary of Western knowledge never flowed into the mainstream of traditional Chinese-style knowledge in Japan. The introduction of Western knowledge amounts, at best, to a mere page in Japanese scientific history, which was categorically dominated by contemporary Chinese science. Westerners were too distant from Kyoto, had little encounter with specialists in mainstream Japanese scholarly life. Frequent relocations of their Jesuit educational institutions compounded Jesuit difficulties in trying to transmit Western knowledge to Japan. On Nagasaki, the Dutch were prohibited from bringing any books other than those related to navigation and medicine, and were not permitted to study Japanese. No more than nineteen Dutchmen were ever at Dejima at once, and nearly none were scientists. The Dejima Dutch community at Nagasaki (est. 1641) were not effectively utilized to explore Western learning and science until the eighteenth century, when Japanese attitudes towards the West were somewhat revised. Dutch intellectual influence was almost nonexistent, consisting only of offhand help on rare occasions related to Japanese inquiry of cosmology and surgery.
In China, the Jesuits made direct contact with the scholars in the capital and other intellectual centers, produced many important translations, including scientific works, and a few were even appointed to posts in the central administration. No such claim can be made for the Jesuit enterprise in Japan in the late sixteenth and early seventeenth centuries. The isolation policy had the result of expulsion of non-Japanese Catholics, suppression of their native converts, and closure of the nation to most international intercourse. Adopting Western techniques was not as simple as importing ready-made goods. Certain elements in the performance of these skills were more or less different from the technical functions learned through use of Chinese-style techniques, and the new methods, such as Western nautical instruments, had to be learned the hard way through observation and trial and error. In Japan there were no organized institutes of instruction and the language barrier was formidable.
When Dutch learning was eventually popularized (Rangaku), it was monopolized by the Nagasaki interpreters at Dejima until finally broken around 1774.
