Aosa & Shirasu Umami Oil Topping

Japanese Seaweed & Baby Sardines Infused in Savory Aromatic Oil

Aosa is a type of Japanese green seaweed known for its light, breezy ocean aroma and crisp texture.

In this topping, aosa from Fukushima’s coastal Matsukawaura area is combined with fragrant dried shirasu (baby sardines) and slowly infused in savory aromatic oil.

Just a spoonful brings a clean, well-rounded umami that blends effortlessly into everyday dishes.

Taste Profile — Easy to Enjoy, Even for First-Time Seaweed Users

• Light ocean aroma
  Refreshing like a coastal breeze, without any strong fishiness.

• Natural umami from shirasu
  Lighter and softer than anchovies, with a mild, pleasant saltiness.

• Crisp aosa texture
  Delicate and slightly crisp, similar to thin basil flakes.

• Balanced savory oil
  Aromatic sesame oil ties the flavors together for a clean, versatile finish.

The combination is distinctly Japanese, yet familiar and easy to pair with Western and Asian dishes alike.
