Nagatanien Matsutake Osuimono: Instant Suimono Soup

Japanese soup comes in two types. One is Miso-Shiru (味噌汁: miso soup), and the other is Suimono (吸い物) or Osuimono (お吸い物).

Miso soup is a representative Japanese soup seasoned with miso (fermented soybean paste).

Suimono Soup

On the other hand, Suimono is usually lightly seasoned with salt and soy sauce and doesn’t contain many ingredients in the broth.

As with miso soup, the clear soup Suimono is a staple soup dish in Japan, so it is also available in instant form.

Among such products, this Matsutake Osuimono is one of my favorite Suimono soups, which Nagatanien (永谷園) introduced into the market in 1964.

This instant soup has deep-rooted popularity here in Japan, loved by many people. It is a very low-calorie food (only 5 kcal per serving) packed with delicious flavor.


The soup base doesn’t contain real Matsutake (because the mushroom is expensive) but uses a flavoring that recreates its taste. Nagatanien Matsutake Osuimono consists of

Seasoning granules (Salt, Sugar, Katsuobushi bonito powder, Bonito extract, soy sauce), Fu dried wheat gluten, Nori seaweed, Shiitake mushroom, Dried scallion, Seasoning (Amino acid), Caramel pigment, Flavoring, Antioxidant (Vitamin E), Citric acid (Partially including Wheat and Soybean)
