Tsubi Soup Instant Freeze-Dried White Miso Soup Cubes — Aosa Seaweed & Tofu, Vegan

Tsubi Instant Miso Soup Aosa Seaweed & Tofu is a freeze-dried, ready-in-5-seconds vegan miso cube that makes a traditional Japanese cup of soup by simply adding hot water.

This single-serving box contains four individually wrapped cubes formulated with Kyoto-style white (shiro) miso, freeze-dried aosa seaweed, tofu, and green onion. Designed for fast preparation without sacrificing authentic flavor, each cube produces a 6 oz savory broth that reflects generations of Japanese miso craftsmanship. The recipe is vegan, certified gluten free, non-GMO, and free of MSG, artificial colors, flavors, preservatives, and seed oils.

How do I prepare a cup in five seconds?

Preparing Tsubi is intentionally simple: drop one sealed cube into a cup, pour 6 oz of boiling water over it, and stir for a few seconds until the cube dissolves. No stove or utensils beyond a cup and kettle are required, making it ideal for quick meals and travel.

• One individually wrapped cube per 3/4 cup (6 oz) serving
• Stir five seconds—fully dissolves into a clear miso broth
• No cooking, no cleanup—ready wherever you are

What ingredients and dietary benefits does it offer?

Tsubi uses white miso paste as its base and adds freeze-dried aosa seaweed and tofu for texture and umami. The formulation targets clean-label preferences: it’s plant-based, gluten free, and produced from non-GMO soybeans with no added MSG or artificial additives.

• White (shiro) miso for a mild, creamy finish
• Freeze-dried aosa seaweed and tofu included for authentic texture
• Certified gluten free, vegan, and no artificial preservatives

Where can I take these cubes and how long do they last?

Each cube is shelf-stable for 12 months and individually wrapped, so you can store them in a pantry, a desk, a carry-on, or a camping pack. Their compact size and no-refrigeration requirement make them convenient for office lunches, hotel rooms, flights, and outdoor trips.

• Shelf-stable up to 12 months with no refrigeration
• Perfect for travel, work, camping, or quick home meals
• Available in 4-, 12-, and 24-pack options for different needs

How authentic is the flavor and where is it made?

Tsubi cubes are handcrafted from a white miso recipe perfected in Kyoto by sixth-generation miso artisans, then freeze-dried to retain aroma and depth. Ingredients are traceable to specific Japanese farms, and production follows HACCP and ISO 22000 standards to ensure consistent food safety and quality.

• Crafted in Kyoto using traditional fermentation know-how
