The association between "Shimizu" and fish stems from the historical prominence of Shimizu Port in the Shizuoka Prefecture, which has long been one of Japan’s largest and most important hubs for tuna and skipjack landings. While the Shimizu Corporation (the construction firm) is not involved in fisheries, the location of Shimizu (the ward/port) is famously associated with the high-quality maguro (tuna) trade. Specifically, Shimizu Port is legendary for its massive landings of sashimi-grade tuna, including bluefin, bigeye, and yellowfin varieties. The local seafood markets and culinary traditions in the region around Shizuoka are deeply connected to the tuna fishing industry, making it a famous pilgrimage site for seafood enthusiasts and professional chefs who travel specifically to secure the freshest tuna available from the Pacific coastal waters that land at the port facilities in the Shimizu area.
