hooligans in japan

hooligans in japan?

went to watch a football match in tokyo and this sign was posted in the entrance of the home backstand side. translated it reads 'no one wearing away goods is permitted past this point. home fans area' apparently they had some issues when some away fans wandered into the home side backstand and they got beat up or tussled. yes, football hooligans in japan! now only if they could play ball like in europe... was a terrible game that was only saved by the beer.
