The US military has banned all troops stationed in Japan from drinking alcohol, following a deadly crash on Okinawa island linked to drunk driving. In a statement, the US military announced that soldiers on Okinawa are banned from leaving their base and their residences. <br/><br/>The military also announced mandatory training to address responsible alcohol use, risk management and acceptable behaviour for all its troops across Japan. <br/><br/>The move comes after a US soldier crashed his truck into a mini van, killing the local driver of the other vehicle on Sunday. Okinawa hosts more than half of the US troops in Japan but locals have long resented the heavy military presence.
