One of the most chilling stones is located in the village of Aneyoshi.

The 10-foot-tall tablet reads: High dwellings are the peace and harmony of our descendants.

Remember the calamity of the great tsunamis.

Do not build any homes below this point.

Other stones offer broader yet essential advice.

There are also tablets that indicate ground high enough to be safe from a fatal wave.

The slabs dot Japan’s coastline, and some are over 600 years old.

While some groups are aware of the threat, others have built communities closer to the ocean.

The tsunami stones are warnings across generations, telling descendants to avoid the same suffering of their ancestors.
