Japanese authorities have unveiled plans to build a giant 250-mile long sea barrier to protect its coastline from devastating tsunamis.
According to the proposals, the £4.6bn ($6.8bn) barrier would reach 12.5m high in some places – stretching taller than a four storey building.
It would be made out of cement – and actually be composed of a chain of smaller sea walls to make construction easier.
The plan comes four years after a huge tsunami ravaged Japan’s north-eastern coast.
