Fukuzawa Yukichi is, of course, the most famous Japanese educator. His head is printed on Japan's 10,000 yen (10,000 yen is the largest denomination paper money in Japan), and he is known as the father of modern education in Japan.

Fukuzawa Yukichi founded a private school and taught many excellent students. Later, this private school grew bigger and bigger, and now it is Keio University, a top university in Japan.

But Fukuzawa Yukichi also has a black spot, that is, he visited Europe in his early years and saw the war-torn European continent. After returning to Japan, he thought that Japan, as an island country, had little development potential and wanted to expand its territory, so it had to invade.
