[00:00:00]A Japanese mapmaker, named Ino Tadataka, was blind in one eye. At 70, he began walking across Japan with a telescope and compass, measuring coastlines and mountains on foot. For 17 years, he mapped an entire nation with extraordinary precision. He died before completion. His apprentices finished the work. Japan's government classified the maps as military secrets for 50 years.

[00:00:28]When finally revealed, they were so accurate that modern surveyors still reference them. A blind man saw Japan clearer than anyone.
