A recent series of crimes has sparked anger over the presence of US military bases on the southern Japanese island of Okinawa. First came the arrest of a former US marine for the rape and murder of a local woman, then, two weeks later, a sailor was arrested for causing a crash while driving under the influence of alcohol. In response, tens of thousands of people took part in a demonstration demanding the closure of the US bases. Our team reports from Japan.
