Allowed people to see the direction and to some extent the intensity of wind.
The windsock was invented in the early 20th century, around 1915, by Albert J. Lindstrand, a Swedish aeronautical engineer. It was originally used in aviation to indicate wind direction and strength for pilots during takeoff and landing.

A Japanese windsock is known as a "koinobori" and is a decorative item shaped like a carp fish. It is traditionally flown in Japan to celebrate Children's Day, as the carp symbolizes strength and success. The windsock is usually displayed outdoors, and the number of fish on the string represents the family members in order of their age.
