A large number of sardines washed up on the shore along the coast of Mukawamachi, Hokkaido, on Monday.
The fish were found at around 6 a.m. by local fishermen who said the sardines had washed ashore along a four-kilometer stretch of coastline, Hokkaido Shimbun reported Tuesday.
One fisherman, 74, told media that he had never seen so many fish washed ashore in his life.
Fishing and marine experts believe that a large number of the sardine's natural predator, the yellowtail (also known as Japanese amberjack), may have been hunting the sardines and causing them to group together as they attempted to flee from their pursuers. In their escape, the large schools of fish may have accidentally come too close to the beach and washed up along the shore.© Japan Today
