Datsu-A Ron “On Leaving Asia”—from the Jiji shinpō newspaper, March 16, 1885

(Published anonymously but generally attributed to Fukuzawa Yukichi)

International communication has become so convenient these days that once the wind of Western civilization blows to the East, every blade of grass and every tree in the East follow what the Western wind brings. Ancient Westerners and present-day Westerners are from the same stock and are not much different from one another. The ancient ones moved slowly, but their contemporary counterparts move vivaciously at a fast pace. This is possible because present-day Westerners take advantage of the means of transportation available to them. For those of us who live in the Orient, unless we want to prevent the coming of Western civilization with a firm resolve, it is best that we cast our lot with them. If one observes carefully what is going on in today’s world, one knows the futility of trying to prevent the onslaught of Western civilization. Why not float with them in the same ocean of civilization, sail the same waves, and enjoy the fruits and endeavors of civilization? The movement of a civilization is like the spread of measles. Measles in Tokyo start in Nagasaki and come eastward with the spring thaw. We may hate the spread of this communicable disease, but is there any effective way of preventing it? I can prove that it is not possible. In a communicable disease, people receive only damages. In a civilization, damages may accompany benefits, but benefits always far outweigh them, and their force cannot be stopped. This being the case, there is no point in trying to prevent their spread. A wise man encourages the spread and allows our people to get used to its ways.

The opening to the modern civilization of the West began in the reign of Kaei (1848– 1858). Our people began to discover its utility and gradually and yet actively moved toward its acceptance. However, there was an old-fashioned and bloated government that stood in the way of progress. It was a problem impossible to solve. If the government were allowed to continue, the new civilization could not enter. The modern civilization and Japan’s old conventions were mutually exclusive. If we were to discard our old conventions, that government also had to be abolished. We could have prevented the entry of this civilization, but it would have meant loss of our national independence. The struggles taking place in the world civilization were such that they would not allow an Eastern island nation to slumber in isolation.

At that point, dedicated men recognized the principle of “the country is more important than the government,” relied on the dignity of the Imperial Household, and toppled the old government to establish a new one. With this, public and the private sectors alike, everyone in our country accepted the modern Western civilization. Not only were we able to cast aside Japan’s old conventions, but we also succeeded in creating a new axle toward progress in Asia. Our basic assumptions could be summarized in two words: “Good-bye Asia (Datsu-A).”

Japan is located in the eastern extremities of Asia, but the spirit of her people have already moved away from the old conventions of Asia to the Western civilization. Unfortunately for Japan, there are two neighboring countries. One is called China and another Korea. These two peoples, like the Japanese people, have been nurtured by Asiatic political thoughts and mores. It may be that we are different races of people, or it may be due to the differences in our heredity or education; significant differences mark the three peoples. The Chinese and Koreans are more like each other and together they do not show as much similarity to the Japanese. These two peoples do not know how to progress either personally or as a nation. In this day and age with transportation becoming so convenient, they cannot be blind to the manifestations of Western civilization. But they say that what is seen or heard cannot influence the disposition of their minds. Their love affairs with ancient ways and old customs remain as strong as they were centuries ago. In this new and vibrant theater of civilization when we speak of education, they only refer back to Confucianism. As for school education, they can only cite [Mencius’s] precepts of humanity, righteousness, decorum, and knowledge. While professing their abhorrence to ostentation, in reality they show their ignorance of truth and principles. As for their morality, one only has to observe their unspeakable acts of cruelty and shamelessness. Yet they remain arrogant and show no sign of self-examination.

In my view, these two countries cannot survive as independent nations with the onslaught of Western civilization to the East. Their concerned citizens might yet find a way to engage in a massive reform, on the scale of our Meiji Restoration, and they could change their governments and bring about a renewal of spirit among their peoples. If that could happen they would indeed be fortunate. However, it is more likely that would never happen, and within a few short years they will be wiped out from the world with their lands divided among the civilized nations. Why is this so? Simply at a time when the spread of civilization and enlightenment (bummei kaika) has a force akin to that of measles, China and Korea violate the natural law of its spread. They forcibly try to avoid it by shutting off air from their rooms. Without air, they suffocate to death. It is said that neighbors must extend helping hands to one another because their relations are inseparable. Today’s China and Korea have not done a thing for Japan. In the perspectives of civilized Westerners, they may see what is happening in China and Korea and judge Japan accordingly, because of the three countries’ geographical proximity.

For example, the governments of China and Korea still retain their autocratic manners and do not abide by the rule of law. Westerners may consider Japan likewise a lawless society. Natives of China and Korea are deep in their hocus pocus of nonscientific behavior. Western scholars may think that Japan still remains a country dedicated to the yin and yang and five elements. Chinese are mean-spirited and shameless, and the chivalry of the Japanese people is lost to the Westerners. Koreans punish their convicts in an atrocious manner, and that is imputed to the Japanese as heartless people. There are many more examples I can cite. It is not different from the case of a righteous man living in a neighborhood of a town known for foolishness, lawlessness, atrocity, and heartlessness. His action is so rare that it is always buried under the ugliness of his neighbors’ activities. When this influence become apparent, it will indirectly affect our normal conduct of diplomatic affairs. How unfortunate it is for Japan.

What must we do today? We do not have time to wait for the enlightenment of our neighbors so that we can work together toward the development of Asia. It is better for us to leave the ranks of Asian nations and cast our lot with civilized nations of the West. As for the way of dealing with China and Korea, no special treatment is necessary just because they happen to be our neighbors. We simply follow the manner of the Westerners in knowing how to treat them. Any person who cherishes a bad friend cannot escape his bad notoriety. We simply erase from our minds our bad friends in Asia.
