Are Sanada Yukimura, Hattori Shimada Hanzo and Abe Seiming the Three Masterpieces of Japanese Culture?

First of all, this is half right. Yes, they can represent samurai, ninja, yin and yang teachers. But it's not all the peak.

As far as samurai are concerned. Understanding is different. Sanada Yukimura is regarded as "the first Japanese soldier" by Konka, but not necessarily the peak of samurai. Kusunoki Masashige (a famous soldier in the Southern and Northern Dynasties), Genanjing (a famous soldier in the Battle of Genping) and Uesugi Kenshin (a Japanese military god) are all outstanding representatives of samurai. Who is the peak depends on what you think.

For ninjas, Hattori Shimada Hanzo should be the pinnacle. Because ninjas are mysterious, the specific age of formation is generally considered to be the early Warring States period. Probably before and after the rebellion in Ren Ying, ninjas were generally unknown, so there were few famous ones. Plus Hattori's achievements and Tokugawa shogunate's propaganda. It can be said that this is a peak.

As for the teacher of Yin and Yang, it goes without saying that Abe Harumi is a must. He is the first division of Yin and Yang in Japan, and his family has produced three major divisions of Yin and Yang in Japan. At the same time, a man named Lu Wudao Man is also very famous. So personally, I think they are all the same except the samurai.

There are many Yamato cultures, such as tea ceremony, kendo, harmony songs, architecture, kimono and so on, which are still very interesting.
