The territory of Japan consists of four large islands, Hokkaido, Honshu, Shikoku, and Kyushu, and more than 3,900 small islands. It faces the ocean in the southeast and northwest. The island lacks resources, the land is barren, and it is often hit by volcanoes, earthquakes, and tsunamis. Survival is really difficult. However, its economy is developed and its civilization has spread far and wide, and it is actually a powerful country in the world. The secret of this cannot be known. And because China has been repeatedly bullied by Japan in the past century, even today, there are Japanese right-wingers who clamor for violating our territorial sovereignty all day long. There is a saying that "you must not have the intention to harm others, and you must have the intention to guard against others." There is also an ancient saying: "Know yourself and the enemy, and you will be victorious in every battle." If you want to protect yourself and strengthen yourself, you must know the details of Japan.
