Kombu Tea (Kelp Tea) vs Ume Plum Tea vs Shiitake Tea

It is said that drinking green tea every day is good for health, for the beverage contains plenty of healthy components such as catechin and theanine. In fact, many benefits can be expected from the intake of the tea. If I give several examples of such health benefits, they are as follows,

  • Cancer prevention
  • Prevention of arteriosclerosis and hypertension
  • Fat absorption inhibition
  • An antioxidative effect that helps keep beautiful skin
  • A relaxing effect
  • Recovery from fatigue
  • Lowering the risk of heart attack
  • Obesity prevention

However, don’t you want to keep your health by drinking more tasty tea like soup? For those who agree with this, today I will introduce 3 different varieties of unique Japanese tea, that is, Kombu tea, or Japanese “Kombucha” (昆布茶: kelp seaweed tea), Ume plum tea, and Shiitake tea. They all taste quite good as though they are soups.

Although I’m a Japanese man born and raised in Japan, I don’t consume Japanese green tea very much in daily life, rather prefer drinking coffee. Instead, I sometimes have a craving for these 3 soup-like teas, and among them, I like Kombucha the most. Then, what kinds of beverages are Kombu tea, Ume plum tea, and Shiitake tea? Today, let me talk about that.

Kombu Tea (Kelp Seaweed Tea)

Kombu Tea (Kelp Tea)

Kombu-Cha (昆布茶)“, literally Kombu (kelp seaweed) tea, is a little salty, umami-rich, tasty tea. Since its base powder is made by pulverizing Kombu, a species of seaweed that is used in making Dashi soup stock, this Japanese tea is especially characterized by its umami taste.

In Japan, Kombu tea is most commonly drunk among these 3 soup-like teas, and its base powder actually can also be used as a seasoning in cooking, instead of salt or soy sauce. The kelp seaweed tea tastes very good, but its salt content is high so you shouldn’t drink it too much in a day.


It is said that drinking Kombu tea properly is good for health because kelp tea is a rich source of minerals and healthy components such as potassium, alginic acid, and iodine. The Japanese seaweed tea is caffeine-free and you can expect the benefits shown below by taking the tea properly.

  • Prevention of arteriosclerosis, high blood pressure, and cancer
  • Lowering cholesterol
  • Prevention of swollen feet
  • Relief of constipation
  • A dieting effect

Ume Plum Tea (Ume Kombucha)

Ume Plum Tea

Ume plum tea, also known as “Ume Kombucha (梅こんぶ茶)”, is a little salty, acidic-sour, umami-rich tea whose base powder is made from powdered Kombu and particles of Umeboshi plums. As with the seaweed tea Kombucha, Ume plum tea is also commonly drunk in Japan. The plum kelp tea is refreshing and very delicious, but you shouldn’t drink it too much in a day because its salt content is also high.


Ume Kombucha has the same benefits as kelp tea, so drinking Ume plum tea properly also promotes health. Plus, it contains healthy components of Umeboshi plums, such as citric acid, from which you can expect recovery from fatigue.

Shiitake Mushroom Tea

As its name indicates, the base powder of Shiitake tea is made from Shiitake mushrooms. In recent years, the popularity of this mushroom tea has been increasing in Japan. Shiitake tea is something like a palatable mushroom soup. Containing lots of glutamine acids that are known as umami ingredients, the Japanese mushroom tea also tastes very good. Of course, it is caffeine-free.


The mushroom, Shiitake is a rich source of minerals, so is Shiitake tea. The mushroom tea contains healthy components such as Eritadenine and lentinan, from which you can expect the following benefits.

  • Lowering cholesterol and Prevention of arteriosclerosis
  • Cancer prevention
  • Reducing neutral fat
  • Prevention of anemia and high blood pressure
