‘Tsunami stones’ are ancient warnings written on stone tablets, some over 600 years old, that lie along the northeast coast of Japan.

After a tsunami struck Aneyoshi in 1933, residents moved uphill of a stone they placed that reads ‘Do not build your homes below this point!’, and when the devastating tsunami of 2011 hit, the entire village survived.
