Kendo is a Japanese martial art that descended from the sword fighting techniques that were used in the days of the samurai warriors.
If you ask anyone to name one martial art from Japan, it is probably going to be judo or karate. Judo has been spread all over the world and is practiced as a common way to teach kids and adults self-defense.
While the most popular sport in many parts of the world might be soccer and American Football, in Japan the most popular sport is definitely baseball.
Karate literally means 'empty hand', and it was developed in Okinawa having been influenced by Chinese martial art Kung Fu. Karate is a striking art where practitioners use both hands/arms and feet/legs.
Winter Sports in Japan
If you are fond of skiing and snowboarding, Japan is a great December-April destination for you. There are over 500 ski resorts across Japan from the northern island of Hokkaido to the southern main island of Kyushu, which vary in size from large resorts with dozens of runs to small one-lift slopes.
While judo and karate are the most popular martial arts to practise outside of Japan, sumo is probably the martial art from Japan that appeals most to the imagination. It is indeed quite the spectacle to watch, and many tourists who come to Japan want to incorporate sumo in their itinerary for exactly this reason.
