A Japanese dining table at dusk: steaming miso soup, freshly cooked rice, and sashimi arranged on small plates. Among them sits a bottle that immediately draws attention. The liquid inside is completely clear, yet the label boldly says “soy sauce.” This is Fundodai’s Clear Soy Sauce. Its appearance overturns everything we normally associate with soy sauce, leaving guests momentarily speechless. Even before chopsticks are lifted, curiosity fills the room and conversations begin. This mysterious condiment, with its unusual charm, is quietly becoming a topic of interest both in Japan and abroad.
Clear Soy Sauce is praised not only for its surprising appearance but also for its depth of flavor. Because it has no color, it doesn’t overshadow the natural beauty of the ingredients. Instead, it enhances presentation while still delivering the rich umami and aroma of traditional soy sauce. As a result, it has become popular not only in Japanese cuisine but also among French and Italian chefs, earning recognition across culinary genres. The technology behind its transparency is not just playful experimentation—it is the result of combining long-standing tradition with meticulous innovation.
This innovation stems from Fundodai, a company with more than 140 years of history. Founded in Kumamoto, the company has long supported Japan’s food culture through soy sauce and miso while consistently identifying emerging culinary needs and offering new value. Clear Soy Sauce is a symbolic example of that spirit. Perfecting a method that removes color without sacrificing flavor took years of trial and error and stands as a testament to the company’s craftsmanship.
Tourists from overseas are equally fascinated. Seeing a symbol of Japanese cuisine transformed into something so modern feels like witnessing the very moment when tradition evolves. Clear Soy Sauce is more than just a condiment—it may well be a glimpse into the future of Japanese cooking.
Clear Soy Sauce Overview
Clear Soy Sauce is an innovative condiment developed by Fundodai, a long-established soy sauce maker based in Kumamoto Prefecture. Although completely transparent, it still delivers the full umami flavor of soy sauce. Beyond its striking appearance, its most distinctive feature is the concept of “adding flavor without adding color.” It enhances the natural beauty of ingredients while providing saltiness and umami, earning a place both in professional kitchens and home cooking.
The ingredients follow the basics of traditional soy sauce—soybeans, wheat, and salt. Through fermentation and aging, their umami is carefully extracted. Afterward, Fundodai’s unique refining method removes only the pigment components. This makes the sauce clear while preserving its aroma and flavor. The fragrance is subtle, with a clean and refreshing aftertaste. It is especially valued in delicate dishes where color transfer is undesirable, making it suitable for all types of cuisine.

Fundodai has continued to produce products that make use of Kyushu’s clean water and high-quality ingredients for over 150 years. Its strength lies in protecting traditional brewing methods while also developing products suited for modern culinary trends and international needs. Clear Soy Sauce symbolizes this approach and reflects the company’s philosophy of blending tradition with innovation.
In Japan, it is increasingly used in high-end restaurants, hotels, and traditional dining establishments. Overseas, it has gained strong attention amid the global boom in Japanese cuisine. Especially in Europe and North America, its visual elegance and the new culinary possibilities it offers have drawn interest, with some Michelin-starred chefs incorporating it into their menus. As it expands internationally, the company continues to strengthen its production systems and quality control to uphold the reliability of the “Japan Brand.”
Fundodai aims to keep developing products for global markets while making use of Kumamoto’s natural resources. Clear Soy Sauce is at the forefront of this mission, introducing a new form of traditional Japanese seasoning to the world.
Production Method and Flavor of Clear Soy Sauce
Clear Soy Sauce is created by applying a unique process to standard dark soy sauce to remove its color. Although it looks as clear as spring water, each drop retains the unmistakable character of soy sauce. Its transparency is not achieved through artificial coloring or chemical additives. Instead, pigment molecules are removed through a careful physical refinement process, allowing it to deliver rich umami without changing the natural colors of the ingredients it accompanies.
The production process begins just like traditional soy sauce brewing: soybeans, wheat, and salt are fermented and aged to develop depth and aroma. After aging, a special step separates the pigment components. Multiple rounds of filtration, combined with precise control of temperature and pressure, remove the color while preserving flavor and aroma. Although the liquid appears completely clear, the moment it touches the tongue, the familiar saltiness and depth of soy sauce unfold.
From Process to Palate
Interestingly, the label reads “soy sauce-style seasoning.” This indicates that while it captures the essence of soy sauce, it represents a new category of product. Its aroma is light and gentle, with a clean, refreshing taste and a subtle umami that lingers. It blends seamlessly into dishes that are usually heavy or rich and enhances the natural flavors of the ingredients themselves.
Its transparency introduces a completely new concept: “adding flavor without adding color.” It is ideal for dishes where the dark color of soy sauce was previously avoided, such as white fish sashimi, clear soups, and delicate appetizers. Its versatility also extends well beyond Japanese cuisine. French, Italian, Chinese, and even dessert dishes benefit from its flavor-enhancing qualities.
Clear Soy Sauce is more than an unusual-looking condiment—it represents a new category of seasoning created through a combination of traditional craftsmanship and modern refinement technology.
Culinary Applications and Versatility

The greatest appeal of Clear Soy Sauce is its ability to enhance flavor without altering appearance. Regular soy sauce darkens the ingredients it touches, but Clear Soy Sauce preserves their natural colors. This is especially striking in white chawanmushi, delicately colored carpaccio, or brightly hued vegetable marinades. It adds depth to sashimi, white fish, jellies, and soups without compromising presentation, improving the overall finish of the dish.
The official website showcases a variety of creative recipes such as “Cod Sautéed with Butter and Soy Sauce,” “Cream Cheese Marinated in Clear Soy Sauce,” and “Carpaccio with Clear Soy Sauce Jelly.” These dishes highlight the playful contrast between the clear appearance and the rich flavor. In jelly form, it shines beautifully under the light, making it a striking addition even to restaurant course menus.
Its uses extend well beyond Japanese cuisine. It complements Western, Chinese, and even dessert dishes. Adding it to caramel sauce or pudding introduces a subtle saltiness that enhances sweetness, creating a refined, well-balanced flavor. A few drops in cheesecake or ice cream leave a gentle umami note in the aftertaste, transforming them into sophisticated, adult-friendly desserts.
For meat dishes, using it as a finishing touch on steak or roast beef adds saltiness and umami while preserving the meat’s natural color. For vegetables, adding it to light pickles or salad dressings enhances flavor without dulling vibrant colors. It also pairs well with pasta and risotto, where its synergy with olive oil or butter enhances aroma.
Clear Soy Sauce, with its unique feature of adding flavor without adding color, expands creative possibilities for professional chefs and brings new enjoyment to home cooking. Its ability to preserve visual appeal makes it perfect for dishes that shine on social media, contributing to its growing popularity among food enthusiasts.
The Story Behind Its Development and Challenges
The creation of Clear Soy Sauce was driven by the persistence of Fundodai’s engineers and their deep respect for tradition. At first, removing pigment from soy sauce while preserving its flavor was considered nearly impossible. This is because the brown color of soy sauce naturally develops during fermentation and aging, carrying with it the aroma and umami that define its character. Removing the color risked losing the distinctive depth and richness of flavor.
Even so, the development team, motivated by a strong mission to create “the soy sauce of the next era” in honor of the company’s 150th anniversary, launched the project. Although there were skeptical voices within the company, its culture of embracing challenges supported the effort, and prototyping continued for years.
Overcoming Development Challenges
In the early stages, transparency was achieved, but the flavor often became too weak, or the signature aroma of soy sauce disappeared, resulting in repeated setbacks. Production costs and maintaining consistent quality in mass production added further difficulties. It soon became clear that the goal required more than simply “removing color.” A new methodology was needed to preserve the essential character of soy sauce.
The team began by reexamining their choice of raw materials. They fine-tuned the varieties and ratios of soybeans and wheat, as well as fermentation temperatures and aging times, carefully testing the balance between color and flavor. They also developed a proprietary filtration method during refining that selectively removes pigments. This advanced process combines micro-fine filtration with precise temperature and pressure control to achieve clarity while preserving aromatic compounds.
The finished Clear Soy Sauce resulted in an innovative seasoning that looks like water but delivers unmistakable soy sauce umami. When it first launched, many consumers reacted with surprise, asking, “Is this really soy sauce?” and it quickly became a hot topic on social media. Professional chefs also welcomed the new culinary possibilities of “adding flavor without adding color,” which led to rapid adoption, especially in visually delicate dishes such as French cuisine and traditional Japanese fare.
One member of the development team commented in an interview, “The greatest challenge was passing on the flavor we’ve preserved for 150 years to the next generation in a new form without compromising it.” The success of Clear Soy Sauce symbolizes not only Fundodai’s technical expertise but also its spirit of honoring tradition while embracing change.
