Japan has carried out exercises to see whether a missile defence shield could be deployed in the capital, Tokyo.
A team of about fifty troops set up radio masts and tested communications at a park (Shinjuku Gyoen) close to the city's major business and entertainment districts.
The military wants to see whether Patriot missiles - designed to shoot down an incoming missile, possibly from North Korea - could be deployed at such sites.
