Big Tokyo Quake To Cram Streets In Rush For Home JAPAN: April 4, 2008 TOKYO - A big earthquake in Tokyo during the day would force more than 12 million people to try to walk home, cramming streets and causing confusion, the government said. Tokyo's transport network would stop running, leaving people with journeys of up to 15 hours on foot to get home on roads packed with people -- possibly more than six people per square metre (11 square feet), similar to a rush-hour train, it said.
