Our Commitment to Sustainability

Sure, we could serve bluefin tuna like the other guys, but what a lot of people don’t know is that it is perilously on the edge of extinction. In fact, nearly 75% of the world’s fisheries are fished to capacity or overfished.


Our seafood choices have the power to make this situation worse or improve it. Although there is no international policy regarding this, we believe in sustaining wild, diverse and healthy ocean ecosystems that will exist long into the future.


We do our part by purchasing seafood that is fished or farmed in ways that don’t endanger the fish or harm the environment. When there is scientific uncertainty, we err on the side of conservation. We follow the guidelines and recommendations from the Monterey Bay Aquarium and its Seafood Watch program.


You can learn more and also follow the guidelines by visiting the Monterey Bay Aquarium website and downloading their iPhone/Android app or handy pocket guide. And if you have any questions, don’t hesitate to ask your server or sushi chef next time you visit Masu.
