The Journey Behind Tsubi Soup
I've always loved soup. It's the ultimate comfort food—warming, nourishing, and deeply satisfying. But when I transitioned to a plant-based diet, I struggled to find quick, healthy meal options that weren't salads or sugar-laden bars.
I searched everywhere for an instant soup that was both delicious and healthy—one made with real ingredients, not artificial fillers. What I found were soups filled with MSG, seed oils, synthetic additives, and highly processed plant-based proteins.
That's when I realized that if I wanted a better instant soup, I'd have to make it myself. So, I did! I bought a food dehydrator, squeezed it into my tiny kitchen, and began experimenting.
My goal?
To create an authentic Japanese miso soup packed with real vegetables and premium ingredients that tastes like home.
What started as a personal project quickly grew into something bigger. People from all over the world connected with my mission. They, too, were searching for something better.
In 2017, I took the leap, left my corporate career, and made Tsubi Soup my life's work.
Today, our soups are enjoyed worldwide, but our mission remains the same: To redefine convenience food—by making instant meals that invigorate you, not just fill you up.
