Well, I'm very interested in Japan and Japanese culture. I have a large collection of books. If you have patience, time. I suggest you read Tokugawa Ieyasu written by Yamaoka Sōhachi. This book is mainly about Tokugawa Ieyasu, a famous general in the Warring States Period. This book profoundly reflects the national essence of the Japanese with this history. One in seven Japanese people has read it. Kōnosuke Matsushita, the founder of Panasonic Group, asked every employee to read carefully. Former Japanese Prime Minister Nakasone Yasuhiro also said that whenever you encounter political difficulties, you should think about how Tokugawa Ieyasu did it. In a word, its value is quite high. If you are short of time. Then study chrysanthemums and knives. Benedict noticed. Although the Japanese nature is thoroughly exposed, this book's understanding of the Japanese can only stay at an old level and is not applicable to the Japanese now. Therefore, it is necessary to understand contemporary Japan and understand the changes in contemporary Japan. Some of the latest introductions of Japan, I suggest you watch Yan Song Seeing Japan. If you want to be comprehensive. Look at Japan head on. I suggest you watch The Ugly Japanese by Mr. Bai Yang. But if you want to see pictures. Very authoritative. You'd better buy Japan, where great powers are rising. In short, there are still many books, but among the books I have read about Japan, I think these books are the most typical. I hope my advice can help you.
