I believe that people who often watch Japanese movies and anti-Japanese dramas will find that the hat worn by ordinary soldiers in Japan will have two things like curtains hanging behind them. What is the special significance? Although it is ugly, it is actually of great use in war.
First, the humble infantry use it to shield the wind and rain, you know, although the equipment of the Japanese soldiers is very good, but for the low-status infantry, they do not have helmets and other configurations, then they can only use cloth strips to protect their necks, in such a complex environment as the battlefield, more or less will have a certain protective effect on their necks, after all, it is better than nothing! Especially when it rains, it can block the wind and rain, although it is very shabby, it is still a very good configuration.
Second, after the Meiji Restoration, Japan began to learn from the West with great effort, and even the cloth strips on the hats were once discarded, but later the Japanese found that the French legions in North Africa also had strips of cloth behind them, so they began to restore their military hats. Later, it appeared in the Pacific War, the Russo-Japanese War, and the War of Aggression against China.
So fundamentally speaking, maybe the Japanese themselves don't know what use this thing is, but it can be regarded as a real decoration! But whether it is for the Japanese to protect the japanese in the battlefield or to be able to shield them from the wind and rain, or just for a decoration, I have to admit that this thing appears on the hat is really a bit ugly, but in the wartime period at that time, ugly can not be a criterion for an object! It will always be equipped as long as it is useful, and this continued until the end of World War 2, and it has become a representative of the japanese battlefield culture.
