Fukuzawa Yukichi, who introduced British utilitarianism to Japan and advocated natural rights, assumed that human rights were given by Heaven. He considered the development of the civilization to be the development of the human spirit, and it was assumed that one's independence led to independence of one country. Fukuzawa thought that government is for the "sake of convenience", and its appearance should be suitable to the culture. He said that there is no single ideal form of government. In addition, he insisted that Japan should have gone into the continent externally against the Great Powers.
