What is Kohaku Namasu ?
Namasu (なます or 膾) is a Japanese dish in which fish, shellfish, vegetables, etc. are cut into thin strips and mixed with seasonings and vinegar. Kohaku Namasu (紅白なます) is one type of “namasu” made with thinly sliced carrots and daikon radish. The word “kohaku” means “red and white” in Japanese.
The colors of Kohaku Namasu resemble “mizuhiki” (水引), a red and white obi string that is used as a traditional decoration for celebrations and gifts. It is considered a good-luck charm to wish for family peace and because of its resemblance, Kohaku Nasamu is considered an auspicious dish and often served during Japanese New Year celebrations.
Ingredients & Substitution Ideas
While it’s not essential, it’s common to flavor Kohaku Namasu with a citrus fruit such as yuzu. The citrus flavor really compliments the dish and makes it seriously refreshing and addictive! Here are the ingredients I used to make yuzu infused Kohaku Namasu including a few substitutions for ingredients that might be hard to come by.
- Daikon Radish: A key ingredient in this dish with a wonderful crunchy texture. If you can’t get hold of daikon, white turnips or jicama could be used instead.
- Carrot: I use regular orange carrots since they’re easy to find, but since this is “kohaku” namasu, red carrots are great to use if you can get them!
- Salt: Regular sea salt is the best option since it dissolves easily into the pickling liquid.
- Yuzu Juice & Peel (optional): One of my favorite additions to this dish is adding the flavor of Yuzu (citrus). If you can’t get yuzu juice, substitute for lemon juice or an equal amount of vinegar. If you can get fresh yuzu, adding the peel will add wonderful flavor to the dish. If you can’t get it, I recommend orange peel as a substitute.
- Rice Vinegar: It’s best to use rice vinegar for a more authentic Japanese taste, but in a pinch apple cider or sherry vinegar also work.
- Water: Helps balance the flavor of the pickling juice.
- Sugar: Adds sweetness and acts as a preservative. Regular white caster sugar or granulated sugar work best.
- Soy Sauce: Kikkomanis a reliable and affordable option globally. For more insights and alternatives, consultmy comprehensive soy sauce guide.
- Dried Kombu: Adds depth and umami to the pickles. If you can’t get kombu, you can omit.

Visual Walkthrough & Tips
Here are my step-by-step instructions for how to make Kohaku Namasu at home. For ingredient quantities and simplified instructions, scroll down for the Printable Recipe Card below.
STEP
Cut the daikon and carrot
Generally, the daikon and carrot in kohaku namasu are cut into thin “matchsticks” to represent “mizuhiki”. How thin you cut depends on preference, but I personally like slightly thick sticks so that it still has crunch. The ratio of daikon to carrot is usually 2:1.
Start by cutting off the round edges to make a block. The picture only shows daikon, but I use the same process for carrot too. You can peel and cut the leftovers, either adding them to the namasu (although the pieces won’t be uniform) or using them in another recipe such as hotpot.
Then cut the block into thin slices.
Finally, cut the slices into matchsticks about 2-3mm thick.
STEP
Draw out excess moisture
Place the carrot and daikon in a mixing bowl and add salt. Massage the salt into the carrot and daikon, then leave it for 15 minutes. During this time, the salt will extract the excess moisture which will prevent it from watering down the pickling liquid later.
STEP
Make the pickling liquid
While the carrot and daikon are dehydrating, you can prepare the pickling liquid.
If you’re using fresh yuzu, wash and peel off some of the skin then cut it into thin strips. If you can’t get yuzu, you can grate orange or lemon peel instead.
Next, take a sealable bag and add rice vinegar, yuzu juice, water, sugar, salt and soy sauce. Mix them together by scrunching the bag. Once the salt and sugar have dissolved into the mixture, add the yuzu peel and a piece of kombu (dried kelp).
STEP
Squeeze water out of vegetables
Once 15 minutes have passed, squeeze the carrot and daikon thoroughly and pour away the excess liquid.
Squeeze thoroughly
Make sure to remove as much moisture as possible otherwise your pickling liquid will be watered down! Also, do not wash it after it’s been dehydrated!
STEP
Pickle
Transfer the carrot and daikon strips into the ziplock bag, push the air out and seal it up. Store it in the fridge for at least 12 hours, preferably overnight.
STEP
Serve
Serve as a side pickle or as part of a Japanese New Year Osechi meal! For an extra wow factor, some people like to scoop out half a yuzu and serve it in the skin. It’s a beautiful way to present kohaku namasu!
Enjoy!

FAQ
What is the meaning behind Kohaku Namasu in Osechi Ryori?
Osechi Ryori (おせち料理) are dishes eaten during New Year’s celebrations in Japan, and each element of Osechi has various wishes and meanings. The colors of Kohaku Namasu (red and white) are the symbols of celebration, and is associated peace and tranquility.
In addition to this, it is said that the daikon and carrot, which have their roots in the ground and grow straight through the soil, are superimposed on the wish for “stability of the house and family business” and “to keep one’s feet on the ground”.
What is the history of Namasu?
Namasu is said to have originated from China more than 2000 years ago and was made of thin strips of raw meat or fish, such as carp or sea bass. In Japanese, the word “Namasu” originally meant “raw meat”, but in the late Heian period (794-1185) the term was changed to mean fish and vegetables chopped into small pieces and mixed together. From there, the Japanese version of the dish developed, using its own unique ingredients.
Before the Muromachi period (1336-1573), Namasu was made using a condiment called irizake (煎り酒), which was made by adding dried bonito flakes and pickled plums to sake and boiling it down. These days, simple rice vinegar is used, often with the addition of dashi ingredients like kombu (dried kelp) to add umami to the dish. Up until the Edo period (1603-1867), Namasu was consumed as a “main dish” due to it more commonly being made with fish, however these days, it is often made with vegetables and served as a side dish.
Can Namasu be made with other ingredients?
Kohaku Namasu made with daikon and carrot is the most well-known, but there are also regional variations of “Namasu” such as:
Hizu Namasu (氷頭なます): A local dish from cold/north regions, which is made from the cartilage part of the salmon’s snout.
Imo Namasu (いもなます): Namasu made with potatoes from around Iiyama City, Nagano Prefecture.
Mizu Namasu (水なます): Namasu made with fresh horse mackerel and other bluefish.
Nuta Namasu (ぬたなます): A dish of vegetables and seafood dressed with vinegared miso, which is considered as a type of namasu.
Kaki Namasu (柿なます): Kohaku namasu made with daikon radish and carrot with dried persimmon, from Nara Prefecture.
