Go originated in ancient China, centuries before its earliest known references in 5th century BC writing. Buddhist priests had visited China and took the game to Japan around 1,200 to 1,400 years ago. There, the game of GO reached its maximum potential. GO was studied by Japanese warrior class who acquired the passion for it and passed down their techniques to their family members in the same way they did with techniques of sword-making and the code of the samurai. GO's popularity stayed alive as the passion for it spread to all levels of society. Wealthy, poor, old, young, all enjoyed a game of Go. Soon it reached a status equal to that of the tea ceremony in Japan.
Go is mostly popular in East Asia, but has nowadays gained some popularity in the rest of the world as well. Go is noted for being rich in strategic complexity despite its simple rules.
