Locals were puzzled by a large, metal sphere that washed up along a Japanese shore. It triggered a frenzy of speculation.
Authorities are unable to say yet what it is – not even the bomb squad or police sent to investigate.
It is not dangerous, but it is hollow. Many believe it is a type buoy.
Locals have given the find in Hamamatsu, a coastal city, various names such as “Godzilla egg”,’mooring buoy’ and “from space” to be fascinated.
NHK, a Japanese broadcaster, showed footage of Enshuhama Beach officials looking at the rusty metal sphere measuring 1.5m (4.9ft).
