In the early evening of 23 April nearly a hundred people took to the street in front of the Japanese mission to UN organisations in Geneva. The march left the UN building at 18.00 and proceeded to walk to the Japanese mission, stopping for photos at the Canadian mission along the way.
Japanese public broadcasting- NHK- ran an English language news report on the demonstration- which can be seen here.
