What Is Namasu? Japanese Vinegared Vegetables Explained
Oct 04, 2026
Namasu (膾 / なます) is a Japanese dish of thinly cut ingredients seasoned with vinegar. Today, many familiar versions use vegetables such as daikon and carrot, although regional namasu can also contain fish or other seafood.
The category overlaps with sunomono, the wider family of vinegar-seasoned dishes. Namasu is useful to think of as a more specific preparation style: ingredients are usually cut into fine strips or small pieces and dressed with vinegar.
What does namasu mean?
Namasu names a family of finely cut foods dressed with vinegar. Modern recipes often combine crisp vegetables with a sweet-sour vinegar seasoning.
The term has a long history and its meaning changed over time. MAFF’s regional cuisine material notes that older forms could contain raw meat or fish, while later vinegar-based vegetable and seafood preparations became established. That history should not be confused with the way most people encounter namasu today.
What is kōhaku namasu?
Kōhaku namasu is a red-and-white namasu made mainly from carrot and daikon. The carrot provides the red-orange colour and the daikon the white.
It is strongly associated with Japanese New Year food and often appears as part of osechi. The colour pairing, kōhaku, is used in celebratory settings in Japan, but everyday namasu does not have to use this combination.
How is namasu made?
The basic process is to cut the ingredients finely, salt or soften them as needed, remove excess moisture and dress them with seasoned vinegar.
For daikon and carrot namasu, salt draws out water and softens the vegetables slightly while keeping some bite. The vegetables are then squeezed or drained before the vinegar seasoning is added.
What is the dressing made from?
Rice vinegar, sugar and salt are common in simple namasu dressings, but recipes vary. Some versions add citrus, dashi, soy sauce or other seasonings.
MAFF’s yuzu namasu recipe uses yuzu for fragrance as well as vinegar seasoning. Regional versions may use locally available citrus or seafood.
What is yuzu namasu?
Yuzu namasu is a namasu scented and flavoured with yuzu citrus. Daikon and carrot are common ingredients, with yuzu peel adding aroma and colour.
It is especially associated with winter and New Year cooking because yuzu is a winter citrus, although recipes and serving occasions vary.
Can namasu contain fish or seafood?
Yes. Vegetable namasu is very familiar today, but regional Japanese cuisines also include namasu made with fish, shellfish or other seafood.
MAFF records regional examples that preserve this broader use. The word should therefore not be defined as “pickled daikon and carrot” alone.
Is namasu the same as sunomono?
They overlap, but they are not perfect synonyms. Sunomono is the broad category of foods seasoned with vinegar. Namasu usually points to a preparation of finely cut ingredients dressed with vinegar.
A namasu can therefore be understood as part of the wider vinegared-dish world. Japanese culinary categories often overlap rather than forming perfectly sealed boxes.
Is namasu the same as tsukemono?
No. Namasu is dressed with vinegar for eating as a dish; tsukemono belong to the wider world of Japanese pickles and preservation.
The techniques can meet at the edges because salt and vinegar may appear in both. At the table, however, tsukemono and namasu are normally treated as different preparations.
Is namasu raw?
Many vegetable namasu use ingredients that are not cooked with heat, but “raw” is not a complete definition. Salt, vinegar and preparation change the texture, and regional namasu can include seafood that has been treated or cooked in different ways.
It is better to define namasu by the cutting and vinegar dressing than by assuming every ingredient is simply raw.
Why are the vegetables cut thinly?
Thin cutting helps the seasoning reach the ingredient quickly and gives the finished dish a light, crisp texture.
Fine strips also make it easy to combine two vegetables evenly, as in daikon and carrot namasu.
Why salt the vegetables first?
Salt draws out excess water and softens firm vegetables before the vinegar dressing is added. Removing that water helps prevent the final seasoning from becoming too diluted.
The aim is usually to keep some texture rather than make the vegetables completely soft.
What bowl is used for namasu?
A small bowl such as a kobachi works well for an individual portion. The dish is usually served in a modest amount rather than as a large salad.
See Kobachi, Kozara & Mamezara for small Japanese bowl and plate vocabulary.
Is namasu only a New Year dish?
No. Kōhaku namasu is strongly linked with New Year, but namasu as a preparation is broader and appears in regional and everyday cooking.
Separating the New Year version from the larger category avoids turning one famous example into the whole definition.
Does namasu vary by region?
Yes. Regional versions can change the vegetables, seafood, citrus and seasoning.
MAFF’s regional cuisine archive documents several forms, including yuzu-scented namasu and seafood-based preparations. The shared idea is vinegar-seasoned, finely prepared ingredients, not one national recipe.
