1. Introduction to Japanese Nori
What’s nori? Nori is an edible seaweed that is shredded and dried to create sheets. Or, nori sheets.
These nori sheets look black and the process of making them is similar to paper-making.
Japanese people have been eating Nori since ancient times and it is a part of many Japanese dishes. Nori is very versatile. You can use it to wrap sushi, eat it with rice, or eat it as a snack.
Japanese nori is popular all over Japan and makes up an important part of Japanese food culture.
Outside of Japan, it is eaten in Korea, where they have their own version called gim. Gim is flavored by sesame oil and salt. In Western countries, nori is eaten as a health food and most people associate it with sushi.
2. So, What Makes Nori Special?
Glad you asked.
Nori is unique because the process of making it is tied into the development of paper-making technology. Before the Edo period, nori was mainly eaten as a paste. But then, Japanese people realized they could use the same technology for paper-making in nori. So, the Edo period was also the time when sushi became popular. And, this is why many types of sushi contain nori.

Another reason why Japanese people love nori is that it’s a great way to hold rice. In part 3, you’ll learn all about all the kids of Japanese Food that contain nori. The dry sheets help keep your hands clean when you’re eating sushi, rice balls, or mochi (sticky rice). Nori also adds a depth of flavor to the plain rice.
In terms of nutritional benefits, nori is extremely healthy. It contains protein and valuable vitamins such as vitamin A and vitamin B. Nori also contains niacin, iron, and zinc.
Japanese Nori contains:
- Vitamin A
- Vitamin B
- Vitamin C
If we’re going to mention benefits, then we should also include health risks too. Daily consumption of too nori is discouraged due to toxic metals and/or amphipod allergens (crustaceans). So, long story short: Don’t eat too much every day.
“However, Porphyra sp. contains toxic metals (arsenic and cadmiun) and/or amphipod allergens, the levels of which vary significantly among nori products. Further evidence from human studies of such beneficial or adverse effects of nori consumption is required.”J. Agric.

4. Different Types of Japanese Seaweed
So, Japanese Nori aside…
There are other types of Japanese sea weed. You’ll see pictures for each one and the pictures are linked (affiliate) to Amazon where you can learn more. Take a look…
A) Ao nori (green laver)
Although it contains the name “nori”, this seaweed is a completely different seaweed from nori. In Japan, ao nori is dried into flakes and sprinkled as a topping to many dishes! These dishes include takoyaki, okonomiyaki, yakisoba, and even tempura. It has a green color, and it is a good source of calcium, magnesium, vitamins, and amino acids.

It has a jelly-like texture that is also high in fiber, though you’d mostly find it sold in powder form. Outside of Japan, it has become a popular plant-based alternative to gelatin.
Hijiki is a black colored seaweed that’s been eaten in Japan since ancient times. It’s usually simmered together with other ingredients like tofu, vegetables, or fish. Hijiki is a great source of fiber, calcium, iron, and magnesium. However, outside of Japan there are warnings for eating too much hijiki because it contains small amounts of arsenic.
This seaweed is usually dried and soaked in water before eating. It’s used in soups and salads. The most common dish with wakame is miso soup. It’s said that wakame can help with burning fat and contains healthy nutrients like omega 3.
Mozuku is a unique superfood that is found in Okinawa, Japan. This is a brown colored seaweed that can be helpful against cancer. It’s usually eaten with a vinegar sauce.
G) Umi budou (sea grapes)
