1904, 2 1 year old, Takano 56 graduated from the naval school. As a second lieutenant, he worked on the warship "Golden Sun" and immediately took part in the Russo-Japanese War. After the end of the Russo-Japanese War, Takano 56' s position in the navy continued to rise. He served as a lieutenant in 1907 and a captain in 1909, and became an instructor of Zonggu detachment of the training fleet to guide interns. 1910121,Takano 56 was admitted as a Class B student in a general school by the Naval University, studying naval guns, mines and navigation. 19 14 was once again registered as a class A student of the general school by the Naval University. 19 15 was awarded the fourth-class Ruibao medal and promoted to the rank of naval petty officer. After the baptism of war and higher education, Gaoye 56 has gradually matured in all aspects. He is still silent and expressionless, but he can ponder over any major issue, think carefully and think independently. Once he makes a decision, he will act boldly and leave a deep impression on the people around him. During this period, two more important things happened in Takano's life. One is to change his surname to Yamamoto, and the other is to marry Reiko Kobayakawa Guangqiao.

Nagaoka, the hometown of Takano 56, is a place where Bushido spirit prevails, with a long feudal history and strong remnants of feudal thought. After the Warrior's War, Nagaoka's position in the whole country plummeted, and it often became people's talk. Nagaoka warriors are ashamed of this and are always ready to rally and shake Nagaoka again. Samurai believes that the best way to make Nagaoka famous is to cultivate noble families. As a result, Nagaoka people invariably turned their attention to the rising star Takano 56. Because the 56th Gate was a general, it could not represent Nagaoka in reputation, and the Yamamoto family, the most famous family in Nagaoka, had no heir after Chen Wu War, so some people began to plan the activity of changing Takano's surname. In this way, Takano 56 can inherit the legacy of Nagaoka famous Yamamoto.

At 19 15, with Takano Shaozuo graduating from the naval university, they saw hope. Because besides Takano himself is a promising naval officer, he is also a descendant of Takano Rongxuan, and he has become an iron friend with ZTE Shizu Mountain in Yamamoto's family, and almost no one else has inherited Yamamoto's mantle. The suzerain Konoha racked his brains and made extraordinary efforts to beg Takano to get married again, and mobilized Takano's parents, such as Tanaka Langjiang and Yamamoto's old minister Watanabe Jilian, to do Takano's work together.

At this time, the Yamamoto family, after the impact of the Meiji Restoration, had already been confiscated by the government and dissipated. As an inheritable property, Xingmiao, the squad leader of Changgang City, only has a faded linen warrior suit and Yamamoto's desolate cemetery. However, the clever Takano 56 did not care about these. He considered the relationship between the Takano family and the Yamamoto family since ancient times. More importantly, Takano 56, who is full of Bushido thoughts, realized that inheriting Yamamoto's legacy has an inestimable role in its future development. Because it is in line with the needs of modern Japanese imperial power system to strengthen the rule by using feudal remnants and expand and invade abroad, in his words, it is a destiny for the Nagaoka vassal to inherit the Nagaoka first family. After much consideration, he agreed to Konoha's request.

1965438+May, 200619, after careful preparation, the most memorable anniversary of the completion of Nagaoka City was chosen and a ceremony was held to change Takano's surname to Yamamoto. Under the proof of his fifth brother, Yoshihachi Takano, the 56-year-old Takano, as the heir of the Yamamoto family, was renamed Isoroku Yamamoto.
