Iwamoto was a Go champion and famously was playing in the "atomic bomb game" outside of Hiroshima when the atomic bomb was dropped. After the war he travelled and created Go centers in North and South America and in Europe. He saw Go as a way to not only promote individual development, but to foster cross communication between cultures and lead to a more peaceful world.
Staffed entirely by volunteers the NGC has a regular schedule of events and classes. It is very welcoming to beginners and there is always instruction, formal and informal for both beginners and more advanced players.
On Saturdays there is Family Go, a program for children where parents can stay and participate as well. With pizza and fun activities, kids learn the game while developing skills in math and logical reasoning. They also learn cultural precepts of the game such as respecting ones opponent and being graceful if losing a game.
The NGC is recognized as a formal chapter within the American Go Association, the official national organization for American Go players, cooperating with similar national organizations around the world. The AGA supports many activities nationally and internationally including publishing the American Go E-Journal and maintaining a national ratings system. The NGC conducts regular AGA rated tournament events that allow measurement of progress and continued growth with game reviews and analysis.
