Japan s Shizuoka Prefecture residents reported a strange metal ball on the beach late last month. Fearing it could be a naval mine, local authorities restricted access to the beach and called in the Self-Defence Forces. A week later, a similar object was discovered in Kagoshima Prefecture.
The Japanese police have restricted access to Enshuhama Beach in the city of Hamamatsu, Japan s prefecture of Shizuoka, after a suspicious ball about 1.5 meters (4.9 feet) in diameter, believed to be made of metal, was found on the shore.
