Kesennuma (気仙沼) sits on the Sanriku coast in Miyagi prefecture, Japan, a region famed as one of the three most productive fishing grounds in the world. In 1611, Spanish explorer Sebastián Vizcaíno proclaimed Kesennuma “the best port in every way”, a sentiment that was to ring true in centuries to come as the city’s port established itself as a popular base for deep-sea and offshore fisheries.
