    The Ancient Japanese Secret to Health and Longevity

    At the heart of Tsubi Soup is miso - a traditional Japanese ingredient made by master crafters in Kyoto, Japan for six generations.


    We use only the highest grade Non-GMO soybeans blended with Koji (Aspergillus oryzae), a natural catalyst for the magical fermentation process that transforms soybean paste into the delicious and nutritious miso paste we use in our soups.


    Our three plant-based blends are carefully crafted to complement the unique toppings in each flavor, ensuring a delicious and satisfying soup every time. During the fermentation process, probiotics and enzymes naturally occur, aiding in long-term digestive health and balance of good bacteria in your gut. Miso is also rich in natural vitamins B's, K's, and E's, as well as minerals, making it a nutritious choice for any meal.


    To ensure the best possible taste and quality, our miso is left to mature for 3 to 12 months in a cool environment, allowing the flavors to develop and intensify. And with its delightful taste and numerous health benefits, it's no wonder they say, MI-SO Happy!

    Cruelty Free and Planet Friendly

    This is a common misconception. Miso soup is not plant-based or vegan due to the traditional use of dashi, a stock made from fish and seafood. Dashi is a crucial component in the making of miso soup, ramen, udon broths and soba. However, at Tsubi Soup, we have crafted a plant-based broth that simmers wild seaweed and shiitake mushrooms to create a deep, hearty umami flavor, without the use of fish or seafood. This ensures that no animals are harmed in the making of our soup.

    Japan has the world’s highest life expectancy rate thanks in large part to their diet, and one of Japan’s greatest superfoods – miso – has played a major role in everyday Japanese cuisine for centuries. Miso is a fermented soybean paste that is rich in probiotics and other essential nutrients that offer numerous health benefits.

    Tsubi Soup uses the highest quality NON-GMO soybeans that have been carefully fermented at a century-old miso maker in Kyoto, a region famous for its ancient miso crafting skills. Our three special blends have been tried and tested to complement the unique ingredients in each flavor.

    Miso is a complete protein, meaning it contains all essential amino acids, making it a great source of protein for vegetarians and vegans. It is also rich in B vitamins, which are essential for energy production, and antioxidants, which are great for anti-aging mechanisms and cell regeneration.

    The fermentation process involved in making miso produces enzymes that aid in digestion and helps to balance the healthy bacteria in your gut, promoting good gut health. Miso also contains a variety of beneficial microorganisms that help to boost your immune system, lower your risk of infections, and reduce inflammation in your body.

    Miso is also a low-calorie food that can help with weight management. It is a great alternative to traditional seasonings that are high in sodium and can lead to high blood pressure, heart disease, and stroke.

    In summary, miso is a nutrient-dense superfood that offers a wide range of health benefits. Incorporating miso into your diet, like in Tsubi Soup, can help to support your overall health and wellbeing.

    2. Retains Nutrients: Freeze-drying preserves the nutritional content of the food. The process of freeze-drying involves removing the water content from the food, but it doesn't remove the vitamins, minerals, and other nutrients that are present in the food.

    3. Lightweight and Portable: Freeze-dried food is lightweight and easy to transport, making it a popular choice for outdoor enthusiasts, backpackers, and emergency responders. Since freeze-dried food is dehydrated and lightweight, it is easy to pack and transport without adding excess weight to your backpack.
