    Not All Soups Are Created Equal

    Tsubi Soup is a freeze-dried, instant soup. The broth and veggies are combined and compressed into a cube (about the size of an AirPods case). Each cube makes one serving of soup.


    All you need is 6oz of hot water and a cup.


    Pour hot water over the cube and watch the miso broth and veggies rehydrate and blossom instantly while releasing beautiful umami flavor profiles and creating the perfect cup of miso soup in seconds.


    We simply wanted to create a snack for the busy and health-conscious person who cares about natural flavors and textures. We wanted to recreate a healthy, homemade soup, without the hassle of cooking.


    Each cube is loaded with vegetables and toppings from the finest ingredients sourced from Japan. Every ingredient is fully traceable, plant-based and gluten-free.


    Yes, it comes in a wrapper, but we are not a processed, junk food.
    There is no MSG, no artificial colors, flavors, or preservatives.

    The Ancient Japanese Secret to Health and Longevity

    The key ingredient in Tsubi Soup is miso. Our miso is crafted in Kyoto, Japan. Our master crafters have been making miso for over 6 generations. Our three plant-based blends have been carefully balanced to complement the unique toppings in each flavor.


    We use the highest grade Non-GMO soybeans with Koji (Aspergillus oryzae), which acts as a catalyst for the magical fermentation process.
    Probiotics and enzymes naturally occur during fermentation and aid in long-term digestive health and balance good bacteria in your gut. Miso also has an abundance of natural vitamins B's, K's, and E's and minerals.


    That's why they say, MI-SO Happy! Oh, and it tastes wonderful too.

    Cruelty Free and Planet Friendly

    This is a common misconception. Miso soup is usually not plant-based.


    The fundamental base ingredient in all Japanese cuisine: 'dashi' is a stock made from broiling down tuna and other seafood. Dashi is a critical ingredient in miso soup and many other soba and udon broths.


    Our dashi is plant-based. Created by simmering wild seaweed and shiitake mushrooms to naturally bring you that same hearty umami and flavorful depth.


    No animals were harmed in the creation of Tsubi Soup :)


    Compare Our Numbers

    Many instant soups are loaded with icky ingredients that you would never find in your own kitchen, not to mention loaded with extreme amounts of sodium that will leave you thirsty for days.


    Miso requires koji bacteria and salt to begin the year-long fermentation journey. It is the crucial ingredient in our soups and this magical fermentation of nature results in an abundance of health benefits that outweigh the salt content.


    Tsubi Soup contains an average of 440 milligrams of sodium per serving which is less than half of our competitors. We've focused on using the best ingredients we can source without overloading them with salt to bring you a gentle but truly satisfying flavor that comes naturally from our miso and vegetables.


    You be the judge.

    Some More Details about Tsubi Soup

    vegan tsubi soup



    Tsubi Soup is a 100% Vegan instant soup cube that delivers all the delicious and nutritional benefits of authentic Japanese miso in an easy-to-make, single-serve package.


    We use a dehydration process called freeze-drying which gently removes the water content from the soup and vegetables, without changing the composition and structure of the ingredients. By using this method we are able to retain up to 98 percent of the nutritional value while weighing only 20 percent of its original weight.

    As a result, Tsubi Soup is super light – weighing a tiny 15 grams – and jam packed full of crunchy vegetables that magically blossom into a fresh soup with the touch of hot water, making it a fast, healthy, and tasty snack for people of all ages that can be enjoyed at any time of day.


    The compact packaging makes it convenient to carry while on the go and has a shelf life of up to 18 months without using artificial preservatives.


    Simply open Tsubi Soup into a mug, pour in 160ml (6oz) of boiling water, and watch the ingredients come to life!

    Feasting on such wholesome goodness has never been easier!

    Today's students, professionals and parents often sacrifice healthy meal choices to stay on top of hectic schedules and tight deadlines. As a result, we're constantly consuming highly processed foods and synthetic additives which can lead to complications like allergies, gastric problems, skin ailments, asthma and even cause cancer. Yet manufacturers continue to inject these toxic ingredients into consumer products for their cheap manufacturing costs and their bigger profits...


    Tsubi Soup is a fast yet satisfying meal that relies only on natural flavors. We believe that every bowl of Tsubi Soup should truly nourish the body, and every ingredient should be something you would find in your own kitchen. Only pure goodness from nature.

    Japan has the world’s highest life expectancy rate thanks in large part to diet, and one of Japan’s greatest superfoods – miso – has played a major role in everyday Japanese cuisine for centuries. Even used in modern cuisine, it has made it's mark as one of the world’s most important superfoods.


    The miso in Tsubi Soup is made of the highest quality NON-GMO soybeans that have been carefully fermented at our 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 also a complete protein, meaning it contains all essential amino acids and is packed with B vitamins and antioxidants, which are great for anti-aging mechanisms and cell regeneration.


    Being a fermented product, probiotics found in miso aid in long-term digestive health and helps balance the healthy bacteria in your gut. It's a perfect savory snack for children and adults.

    Oh, and it tastes amazing too!

    There are so many great reasons to adopt a plant-based diet, from maintaining a healthy weight to increased energy levels throughout the day, better gut health to reducing your impact on the environment.

    You don't have to be a vegan to enjoy Tsubi Soup. In fact, I know many meat-eaters who love Tsubi Soup.

    Its all about baby steps! Try removing meat or dairy one day a week. Go from there and you'll be amazed at how quickly you can see and feel the difference :) There are also global community events like 'Meatless Mondays' where you can participate in the vegan movement even once a week to contribute to the environment and express your support to a healthier and cruelty free lifestyle.
