Koji Market
In the same way that German sauerkraut complements sausages and hearty meat dishes, or American pickles add a refreshing bite to burgers, smoked meats, and barbecue, Japan has its own essential side dish that refreshes the palate. Known as Tsukemono, these Japanese pickled vegetables have been a part of the country’s culinary heritage for centuries. They are the foundation of Japan’s “pickling culture,” bringing vibrant colors and subtle layers of flavor to the dining table every day.
In this article, we will explore not only well-known favorites like umeboshi pickles and Takuan (Japanese pickled radish), but also lesser-known varieties, traditional preparation techniques such as nukazuke pickling, and the many types of tsukemono that make this culinary tradition so rich and diverse.
What is Tsukemono?
Tsukemono is the Japanese term for a wide range of preserved vegetables and fruits, created by immersing them in salt, miso, rice bran, soy sauce, or vinegar. This process enhances both flavor and shelf life. Long before refrigeration, pickles in Japan allowed people to enjoy seasonal produce year-round. Today, there are said to be more than 600 types, from classic oshinko tsukemono to tangy umeboshi pickles, each with its own regional character and place in everyday meals as well as in special occasions like New Year celebrations. These foods are not only a staple of Japanese cuisine but also a reflection of its deep respect for seasonality, balance, and the art of preserving nature’s flavors.
Famous Tsukemono Served with Japanese Cuisine
Have you ever noticed thin slices of pickled ginger served alongside sushi? In Japan, this is called “gari”, a type of tsukemono that is eaten between pieces of sushi. Its purpose is to cleanse the palate, removing lingering aromas and oils from the previous fish so you can better enjoy the next bite.
Another well-known example is the Japanese pickled radish called “takuan”, often made through nukazuke pickling. It is bright yellow, crisp, and slightly tangy, and is commonly used in sushi rolls for both its flavor and texture.
When enjoying Japanese curry, you might find a side of fukujinzuke, a soy-based pickle made from seven kinds of vegetables. This type of tsukemono balances the strong spices of curry, refreshing the palate between bites.
Accompanying Japan’s staple food, rice, is the small, round red umeboshi pickles, reminiscent of the Japanese flag. Among all tsukemono, umeboshi has the strongest sour taste. Its citric acid helps reduce fatigue, while catechins provide antibacterial benefits that can prevent foodborne illness. Traditionally used in lunch boxes and as a filling for rice balls, umeboshi has become one of the most iconic elements of Japan’s pickling culture.
Fermented and Non-Fermented Tsukemono
Tsukemono, the traditional pickles in Japan, can be broadly divided into fermented and non-fermented varieties. Fermented Japanese pickles are created through the action of lactic acid bacteria and yeast, slowly maturing over time. This process develops rich umami and tangy flavors while offering probiotic benefits that support gut health. Though they require patience and care during the fermentation process, their depth of flavor is unmatched.
Non-fermented Tsukemono, on the other hand, are prepared by seasoning vegetables quickly with salt, vinegar, sugar, miso, or soy sauce. These are ready in just a few hours to a day, preserving the vibrant color and crisp texture of the vegetables while providing a refreshing taste. Both styles are valued for their unique roles in Japanese cuisine, whether as everyday sides or accompaniments to special dishes.
Types of Tsukemono
The variety of types of tsukemono is vast, with flavors and aromas changing depending on the ingredients and seasonings used. Some are light and fresh, while others have a distinctive, bold character.
Salt Pickling
The simplest method, uses only salt to draw out moisture from vegetables and preserve them. Lightly salted vegetables, known as asazuke, can be enjoyed within hours, and retain a satisfying crunch. Umeboshi pickles, made from salted plums, are also part of this category.
Soy Sauce Pickling
A savory style where vegetables absorb the rich aroma and umami of soy sauce. These keep well and pair beautifully with rice or ochazuke. Fukujinzuke, often served with Japanese curry, is first salt-pickled and then finished in soy sauce. Beyond vegetables, this method is also used for ingredients like salmon roe or egg yolks.
Vinegar Pickling
The flavor changes depending on the vinegar used, whether rice vinegar, plum vinegar, or apple vinegar. Pickled ginger in sweet vinegar is called gari, while red pickled ginger uses plum vinegar. Rakkyo pickles and even Western-style pickles fall into this category.
Koji Pickling
Made with rice koji, a fermentation starter that imparts sweetness and depth. Well-known examples include Bettarazuke from Tokyo and herring pickles from Hokkaido. Koji pickling is also used for fish and meat.
Nukazuke Pickling
A traditional method where vegetables are buried in a fermented rice bran bed called nukadoko. Daily mixing is needed to maintain quality, but the result is rich in flavor and full of probiotics. This style is beloved among those seeking both taste and health benefits.
There are many other ways to prepare pickles as well. Combining local produce with regional traditions, Japan has over 600 varieties of pickles, each carrying a history that cannot be captured in a single sentence.
Regional Varieties of Tsukemono
Across Japan, each region has developed its own distinctive types of tsukemono, shaped by local climate, available ingredients, and culinary traditions. These unique pickles in Japan highlight the creativity and diversity of the country’s pickling culture.
Iburigakko – Akita Prefecture
In snowy Akita, where sunlight is scarce in winter, farmers traditionally hung daikon radishes above the household hearth to dry. This process infused them with a smoky aroma before they were salted and aged, creating a rich and flavorful form of Japanese pickled radish known locally as iburigakko. The name comes from the regional words for “smoked” (iburi) and “pickles” (gakko).
Sunki-zuke – Nagano Prefecture
The Kiso region of Nagano is far from the sea, where salt was once scarce and expensive. Instead of salting vegetables, locals fermented the stems of red turnips using naturally occurring lactic acid bacteria. This produced a distinctive sour pickle called sunki-zuke, one of the rare salt-free types of tsukemono, prized for its health benefits and unique flavor.
Narazuke – Nara Prefecture
Vegetables such as white gourd, cucumber, eggplant, and even watermelon are first salted, then repeatedly marinated in sake lees until they develop a deep amber color. The alcohol content increases during the process, improving both preservation and flavor. Narazuke is an example of how pickles in Japan can be both luxurious and long-lasting.
Papaya Pickles – Kagoshima Prefecture
In the warm climate of southern Kagoshima, unripe green papaya is thinly sliced and marinated in a sweet soy sauce mixture. The result is a crisp, refreshing pickle that often appears in local dishes, including Amami’s signature chicken rice. This tropical twist on tsukemono shows how the tradition adapts to regional ingredients.

Buying and Making Tsukemono
The seasonings and methods used to make tsukemono vary depending on the type, so it is best to check the Japanese pickles recipe and ingredients before you begin. Many traditional pickles in Japan use simple ingredients such as salt, vinegar, or soy sauce, making them easy to prepare at home. Today, ready-made pickling powders are also available, allowing you to quickly add depth of flavor and aroma to vegetables without complex steps.
How to make lightly pickled Japanese vegetables:
- Wash about 10 to 15 ounces of your favorite vegetables (about 4-5 cucumbers) and cut them into bite-sized pieces.
- Put the vegetables and one 10 gram bag of pickling powder in a Ziploc bag, mix well, remove the air from the bag and seal.
- Refrigerate for 2-4 hours (or overnight for a deeper flavor). Lightly drain and enjoy!
