Why are Japanese bows so long? Is it because a long bowstring is more powerful? Our bow strings are generally shorter, but why the long range?

There are two types of Japanese bows, the Japanese bow and the half-bow. But the former is more common, is very long kind. Absorbing the characteristics of the Han bow and improving on them, such a long bow is easy for the user to control the range and the trajectory of the arrow with experience, and is also very powerful.

The same bow is basically longer and more powerful.

China's bows are different from Japan's and the shape of the bow is different. Japan's bows are basically straight-armed, while China's traditional bows are recurve. For the same arm length, the recurve bow is more powerful. It's not the string material, it's the bow.
