Here is a question about this article: The attacks on the torch in London and Paris were described as "despicable" by the Chinese government, condemning them as "deliberate disruptions... who gave no thought to the Olympic spirit or the laws of Britain and France" and who "tarnish the lofty Olympic spirit", and vowed they would continue with the relay and not allow the protests to "impede the Olympic spirit". Large-scale counter-protests by overseas Chinese and foreign-based Chinese nationals became prevalent in later segments of the relay. In San Francisco, the number of supporters were much more than the number of protesters, and in Australia, Japan, South Korea, the counter-protesters overwhelmed the protesters. A couple of skirmishes between the protesters and supporters were reported. No major protests were visible in the Latin America, Africa, and Western Asia legs of the torch relay.
What is the answer to this question: Who overwhelmed the protesters in Japan?
