The ocean off the Sanriku Coast of Miyagi, is known as one of the world's three most fertile fishing grounds. Tokura district in this area had long produced some of Japan's best oysters. But as the popularity grew, the waters started deteriorating due to over-farming. When the Great East Japan Earthquake of 2011 devastated this coast, GOTO Kiyohiro, a local oyster farmer, made this a chance to make a fresh start. He proposed to the other oyster farmers to cultivate less and plan for sustainability. The sea recovered, and it now produces more oysters, even better quality than before.
