What is the relationship between those Japanese generals in the naval battle in Liang Ming?

They all have different names. They are not related by blood or kinship.

The Japanese navy general played by Seung-yong Ryoo was shot several times, and was finally beheaded by Li Shunchen. He was the only Japanese killed in the invasion of Korea. Of course, he was shot with an arrow. As for being beheaded, it was an exaggeration of Korean art. Laidao was originally from Murakami Suigun in Seto Inland Sea, Japan, and later took refuge in Noshin Oda, who joined Toyotomi Hideyoshi after his death. After he came to the island, he died in Korea. After he came to the island, he took the wrong side in the battle of Guanyuan, occupied the western army against Tokugawa, and was once expelled from the Francisco. But later, with the help of Fukushima and the former Toyotomi who took refuge in Tokugawa, he was spared and regained his fief. Later, Laidao changed its surname to Landao. Viscount Ludao is the descendant of this unlucky name among China people after Meiji Restoration.

In the film, Gao Qiao Fujitani, the commander-in-chief of the Japanese water army's calligraphy practice, is easy to recognize with his helmet with two big hats and wings. At first glance, it must be him. Their family used to be a vassal of Shinoda's brother-in-law, Asai. After Asai's family was destroyed by Oda, it was changed to Oda Nobunaga. Has been under the command of Toyotomi Hideyoshi, became the monkey's old men. After the monkey died, he took refuge in Tokugawa. In the battle of Guanyuan, he made great contributions to Tokugawa's defeat of Xiliang Army. After the war, he became the leader of the Kim family in Yi Shi. After the Meiji Restoration, he became the earl of China. Originally, according to the vassal strength of their family and the order of taking refuge in the Meiji government, it should be the marquis. Just because of his close relationship with the shogunate, he was knighted and dropped by one level when he became an earl.

In the film, the fat man who has been bowing beside Gao Qiao Fujikura should be Kato Jiaming, who defected to Toyotomi Hideyoshi since childhood. He is one of the cheap Yueqi cannons and is regarded as the army of Toyotomi. In the battle of Guanyuan, it was also the East Army that voted for Tokugawa, which saved its prosperity. Although the child was corrupt and renamed by the shogunate, it became worse and worse. However, after the Meiji Restoration, as a vassal of Shuikou, he also mixed a viscount. His name was wrongly written as Katou Kiyomasa in the movie, which was a big mistake. How could Katou Kiyomasa be a follower of Takayasu Fujitani? In addition, in history, Ming Kai Kato and Gao Qiao Fujitani also had disagreements, and there had been disputes over merits and demerits before. In the end, it was the monkey who preferred Fujikura who subdued Kato Jiaming. So Kato can't please Fujikura.

There is also a Japanese general in this battle, that is, Fei Hua Tai Er, who is also one of the seven cannons of Jianyue. However, he was filmed as a soy sauce maker by Koreans in the film. This elder brother carried Li Shunchen twice in the Korean War, and both survived. You can't just say it by luck. In the battle of Guanyuan, he defected with Kobayakawa Hideaki and attacked the western army. After the war, he was rewarded for his achievements and became a vassal of this continent.

In a word, there are basically two sources of the Japanese navy in the war of invading Korea: one is a water thief from Kansai, Japan, represented by the alcoholic Jialong, commander-in-chief of the Japanese navy invading Korea, and the other is a general who came to the island. On the other side are Chen Feng's cronies and upstarts. In particular, the so-called "Seven Yue" Seven Guns were all children of Chen Feng. The two factions don't agree with each other and don't like each other. This disharmony should also be a reason for the poor record of the Japanese navy in the invasion of Korea.
