Introduction to Kurosawa's film: "If a person leaves, will his shadow still exist?" This is a sentence from Akira Kurosawa's movie. Kurosawa is such a person, although he is dead, his shadow still exists. When a person leaves, the shadow is still there, because there is a "god" between "shape" and "shadow".

Before him, when the western world thought of Japan, it was Toyama, geisha and cherry blossoms. From him, when the western world thinks of Japan, Japan is Kurosawa, Sony and Honda. He is known as the "film emperor", which is said to be ironic at first, referring to his persistence and tyranny in directing the scene. Later it became an out-and-out honorific title. His works led the international film art trend in the 1950s and 1960s, and were a monument in the film industry. He was the first Asian filmmaker to break the monopoly of European and American film festivals and was praised as "inspiration from the East".
