Yokosuka’s fresh fish appeal 

Chef Oshima: Yokosuka’s seafood is special because of its freshness. Being surrounded by Tokyo Bay and Sagami Bay, we have access to plenty of fresh ingredients. I personally visit the fishing port and get the freshest seafood from Mr Kuriyama of ‘Yasura Port Kaeimaru’. 

I carefully select the best time of year for each ingredient, and if it’s fish, I age it for three to four days to enhance its flavor. 

In French cuisine, we use every part of the animal to make soups and sauces that showcase the seasonal produce. Don’t miss the chance to try Yokosuka’s local fish and seafood prepared in the French culinary style.
