Welcome to Nichinan

Opened in December 2022 within the elegant Hotel Thaxter, Nichinan brings authentic Japanese cuisine to Portsmouth. Named for our city's Japanese Sister City, a relationship dating back to the 1905 Portsmouth Peace Treaty, our restaurant honors this special connection through culinary excellence. Chef Andrew Swanson crafts guest favorites like Crispy Miso Eggplant, signature sushi rolls, and Wagyu Gyoza, complemented by expertly crafted cocktails and mocktails. Whether you're joining us for an intimate dinner or celebrating in our private Parlor Room, we invite you to experience the harmonious blend of tradition and innovation that defines Nichinan.
