Generally speaking, when the Mongols attacked Japan, Japan had entered the shogunate era, and it was popular in Japan at that time to "ride the war", that is, to fight one-on-one.
What Mongols are not good at is one-on-one combat. You know that the best tactics of Mongols are horse riding and archery, but this can't be used in Japanese island countries. First of all, the sea breeze is particularly strong, and Mongolian bows and arrows are not allowed to shoot (Japanese bows and arrows are flat and have a short range, so they are not greatly affected), so horses can't run away in Japanese beaches and mountains. So I can only be forced to fight hand-to-hand with the Japanese, that is, one-on-one combat.
Think about it, the Mongols who were good at riding and shooting originally could not ride and shoot, so they were forced to dismount and fight one-on-one with the Japanese samurai who had been fighting one-on-one for one or two hundred years. Isn't that death? (Take WOW as an example, a hunter with a talent for shooting goes hand-to-hand with a warrior with a talent for violence ...)
In addition, Mongolian weapons are not suitable for disassembly operations and must not be used conveniently. In addition, the targets of Japanese samurai's "riding war" are basically Mongolian senior generals and commanders, and once these people die, their morale will be in chaos, so there is a rumor that "Japanese swords are very strong" ...
To sum up, the old view is:
1, Japanese Dao does have exaggerated elements in it.
2. There are not many examples of Japanese knives cutting Mongolian weapons, because Japanese knives are not used to destroy other people's weapons, whether it is skill or forging process. ....
3. Mongolians lost to the Japanese in one-on-one combat mainly because Mongolians are not hand-to-hand combat, while the Japanese are just the opposite.
