Tsubi Soup Yellow Miso Soup Cubes — Instant Japanese Miso, Vegan & Gluten-Free (4 Pack, Garden Veggies)

Tsubi Soup Yellow Miso cubes are single-serve, freeze-dried Japanese miso packets that make a hot, plant-based cup of miso soup in five seconds with just hot water.

If you want an authentic, convenient miso experience without a stove or cleanup, these individually wrapped cubes deliver. Crafted in Kyoto by sixth-generation miso makers, the Yellow (awase) miso blend is balanced and versatile, paired with freeze-dried garden vegetables for texture and flavor. Each box contains four shelf-stable packets; larger multi-packs are available for frequent use, travel, or pantry stocking.

How quickly will I have a cup ready?

Your soup is ready in about five seconds: drop one cube into a cup, pour 6 ounces of boiling water, and stir. The freeze-dried cube dissolves almost instantly, producing a traditional 3/4 cup serving sized and seasoned to Japanese miso standards. For a fuller bowl, use two cubes with 12–13 ounces of water.

• Single cube yields a 6 oz serving
• Stirring after pouring hot water dissolves the cube in seconds
• Double the cube for a heartier portion
• No stove, no reheating, no utensils beyond a cup and spoon

What ingredients are in each cube and are they allergy-friendly?

Each cube uses a plant-based recipe built from real fermented Japanese miso and freeze-dried vegetables like spinach, cabbage, carrot, green onion, and shiitake mushroom. The formula is vegan, non-GMO soy, certified gluten-free, and contains no added MSG, artificial colors, flavors, preservatives, or seed oils. Sodium is lower than many instant alternatives, making it a cleaner instant option.

• Fermented miso paste forms the broth base
• Freeze-dried garden veggies for flavor and texture
• Certified gluten-free and non-GMO soybeans
• No MSG, artificial additives, or seed oils

How authentic is the flavor and where is it made?

The recipe is produced in Kyoto by a family of miso artisans using traditional fermentation techniques refined over generations. Ingredients are traceable to specific Japanese farms and processed in HACCP and ISO 22000 certified facilities for food-safety standards. Yellow (awase) miso gives a lighter, balanced profile that mirrors classic Japanese miso soup served across restaurants and homes.

• Made in Kyoto by sixth-generation miso craftsmen
• Farm-to-factory ingredient traceability
• HACCP & ISO 22000 certified production
• Yellow miso offers a mild, versatile broth base

How can I customize a Tsubi bowl?

Start with one cube for a delicate, traditional cup or combine two cubes for a richer serving. The mild Yellow miso complements additions like tofu, cooked rice, soba, seaweed, or extra fresh vegetables so you can build a complete, satisfying bowl quickly. Because cubes are shelf-stable, you can tailor servings anywhere—from office breaks to campsite dinners.

• One cube = light starter; two cubes = richer bowl
• Add tofu, rice, noodles, or seaweed for heartiness
• Fits travel, office, or home meal prep
• Also available in other miso varieties for variety

Who is this for: Tsubi Soup Yellow Miso is ideal for busy people who value authentic Japanese flavor with minimal effort—vegans, vegetarians, celiacs, travelers, office workers, and outdoor enthusiasts who want a fast, clean, hot soup without artificial additives. If you want a traceable, traditionally made miso broth that dissolves in seconds and adapts to many meal styles, these freeze-dried cubes are designed for you.
