Japanese Soy Sauce Maker Hamaguchi Goryō's 1854 Tsunami Actions and Legacy Detailed
In 1854, during a tsunami that struck Hiro, Japan, soy sauce maker Hamaguchi Goryō used rice-straw fires to guide villagers to higher ground in the darkness. This event occurred on December 24, 1854, following the Ansei-Nankai earthquake. Goryō, who nearly drowned himself, returned to help others, setting fires to illuminate the path to Hirohachiman Shrine. The US Geological Survey credits these fires with guiding nine people to safety, though 36 lives were lost. Following the disaster, Goryō financed and oversaw the construction of an embankment from 1855 to 1858. This structure, measuring 652.3 meters long and 3-3.4 meters high, was designed to protect the community from future tsunamis. The embankment proved effective, notably protecting most of Hiro during the 1946 Nankai tsunami, 88 years after its completion. Goryō also provided housing, tools, and fishing equipment to help families rebuild and offered employment through the embankment's construction.
