Translation guide
A large group of mostly marine multicellular algae, including many seaweeds. In Japanese, the most common and general term is 褐藻 (かっそう), used in scientific and everyday contexts. For edible seaweeds, specific names like 昆布 (こんぶ) or ワカメ are more natural.
Referring to brown algae as a biological group (Phaeophyceae) in scientific, educational, or general contexts.
The standard biological term for brown algae. Used in academic, scientific, and formal contexts. Can also be used in general writing when referring to the group as a whole.
褐藻は主に海に生息する。

Brown algae perform photosynthesis.
Referring to edible brown algae commonly eaten in Japan, such as kelp, wakame, or hijiki. In everyday conversation, specific names are used rather than the general term.
Kelp, a type of brown algae used extensively in Japanese cuisine for dashi stock and simmered dishes.

A slightly more formal or written way to say 'brown seaweed'. 褐色 (かっしょく) means 'brown color'.

When talking about edible brown algae, it's much more natural to use the specific names like 昆布 (こんぶ), ワカメ, ひじき, or もずく. Using 褐藻 in a recipe would sound overly scientific.
海藻 (かいそう) is the general term for 'seaweed' and includes green and red algae as well. 褐藻 specifically refers to brown algae. In everyday conversation, 海藻 is more common unless you need to specify the color or biological group.
I put wakame in miso soup.
Simmered hijiki is nutritious.
