Karate, another martial art that originated in Japan, has also become a popular sport and is practiced by millions of people around the world.

The Allied occupation of Japan following World War II brought about major political and social changes, including the drafting of a new constitution and the abolition of the samurai class.

The Taisho period, which lasted from 1912 to 1926, was marked by political instability and social change, including the rise of labor unions and women's rights movements.
