The ancient Japanese soldiers were so short, why the Japanese bow was so long, 2.2 meters, even longer than the British longbow at that time, although the Japanese bow was very powerful.

As far as I know, Japanese bowing is a joke. Due to the backward productivity and low level of social development, the Japanese bow is mainly a single bamboo bow, that is, there is no post-flexion, and many materials are not used to strengthen its tension.

In this case, the Japanese bamboo bow has to provide stronger bow force by adding a long bow arm, just like another famous single bow. Only the longbow in Britain is made of rosewood, and its unit power coefficient is much higher than that of bamboo. Moreover, bamboo is easy to deform and simple to process, but its durability is also much worse.

As for the so-called Mongolian record that the Japanese bamboo bow is more powerful than the British longbow, this is very doubtful. Because Mongols have never been in contact with English longbowmen. When the Mongols swept across Eurasia, the English longbowmen only left their mark in Wales, but they have not yet entered the European battlefield. When the West invaded Europe, Mongolia's main enemies were also Eastern European countries, and it also had a little contact with the governors of Central Europe, and basically did not fight against the Western European powers.

In the war between Mongolia and Japan, the main participants were not the famous Mongolian cavalry, but the newly attached troops after the collapse of the Southern Song Dynasty. Not to mention its combat effectiveness, it is certain that this army has never been to the European battlefield.

Therefore, I really can't imagine how the Mongols put the English longbow and the Japanese bamboo bow together to evaluate.

Finally, Japan's bamboo bow is famous for its poor fighting capacity and low price, and it has been dubbed as a toy by some military historians. Not convinced, the Japanese used modern science and technology to produce a batch of Japanese bamboo bows with excellent performance, which was ridiculed more-because it was impossible to have this level of technology when Japanese bamboo bows prevailed.

As for the so-called peace bow, its specific origin is unknown, especially in Japanese military history. But in general, it belongs to a single bow similar to the English longbow (some people call it Stone Age technology).

Moreover, the bow also has the same characteristics as the English longbow, such as high material requirements, simple manufacturing process, low maintenance requirements, extremely high training requirements and long training time. Qualified archers are bound to suffer from serious spinal diseases in their later years.

Crucially, Kazuo has never shined in Japanese military history. Even in the whole Japanese military history, archers are just a decoration. To tell you the truth, I doubt the so-called bow and arrow very much. It is just a handicraft made by the Japanese using modern scientific research and traditional handicrafts after the bow and arrow is no longer practical.

In other words, no matter how beautiful and powerful the bow of peace is today, it is not a qualified bow that can be put into use in large quantities and play a role in war.

Another thing that needs to be added is that users of English longbows need to be tall to use longbows effectively. As a bow longer than the English longbow, I find it difficult to use without the height of 1.7 meters. In Japan before the end of World War II, I doubt that Japan can find many archers who use longbows to train-you know, qualified longbows need more than 10 years of training.

Japan is so close to China, why is Japan still using a single bow (mainly bamboo bow) instead of learning China's compound bow? Personally, the reasons are as follows:

The manufacturing cost of compound bow is high, the process is complex and the time is long. Manufacturing composite bows requires horns and tendons of cattle and sheep, high-quality wood (more than two kinds), at least five kinds of adhesives and at least three years of processing time.

Similarly, the arrow in the bow and arrow is not much less difficult to manufacture and the cost is not much lower. It needs to be made of special high-quality wood, hairiness, arrows and high-quality adhesives.

Only when bows and arrows are made so finely can they be regarded as soldiers' weapons and penetrate the enemy's leather armor within the range-they are still fragile in the face of real armor.

With Japan's national strength before the founding of the People's Republic of China, I doubt whether Japan has such a level of social development and national strength to produce such complicated and expensive militaristic weapons-of course, Japanese soldiers don't need such weapons, because the bamboo mahjong armor worn by the Japanese can easily penetrate without such a weapon as militarism.

PS:

Among the single bows, the only effective bow is the English longbow, but the English longbow has its particularity. Although the manufacturing process is relatively simple, it requires very high skills of users. In the history of Britain, in order to have enough excellent longbowmen, strict laws were enacted to force all British people to give up all entertainment and leisure. From the age of six or seven, they practiced archery all day besides making a living.

Even so, among the millions of British people who practice bow and arrow, at most, less than 10 thousand qualified longbowmen are selected. Moreover, it is said that all qualified longbowmen are bound to suffer from serious spinal diseases in their later years.

Finally, the actual record of the British longbow is not so dazzling. Several famous victories of the British longbow were achieved by excellent commanders with the most effective and reasonable tactics, giving full play to the advantages of the British longbow as a weapon. Of course, their enemies also cooperated very much, and chose the stupidest tactics to fight according to the baton of the British commander.

In fact, in the battle of Ginkul, the real enemy was not the English longbow, but the dagger of the longbow soldier-the French knight who exhausted his strength on the muddy uphill road. The number of people who were stabbed to death by longbowmen with daggers far exceeded the number who were shot to death by bows and arrows.

Britain's subsequent victory was only due to the political infighting in France.

In the era of Joan of Arc, before muskets were popularized, the English longbowmen were unable to fight against the United French army.
