The origin and much of Wakame seaweed’s history is found in Asia, specifically in Japan. Native to cold temperate coastal locations of Japan, Korea, and China, in recent decades wakame has become established in temperate regions around the world, consisting of New Zealand, the United States, Belgium, France, Great Britain, Spain, Italy, Argentina, Australia and Mexico.

How is Wakame Farmed?

Wakame growing was first studied at Dalian, northeast China, by Japanese scholar Youshiro Ohtsuki who patented cultivation techniques in 1943. Considering that the mid-1960s wakame seaweed has actually been extensively farmed there at a commercial level, however it can likewise be gathered from the wild. In the Republic of Korea, growing of wakame began in 1964, and was mostly developed, promoted and industrialised throughout the 1970s, at that phase accounting for 30% of seaweed farming production in 2013.

In China, substantial production started in the mid-1980s, primarily in 2 northern provinces which have given that become the primary wakame manufacturers worldwide. Consumption of this macroalgae as a seafood is divided in two categories; the processed midribs are consumed inside China, while the sporophylls and blades are mainly exported to Japan and other Asian nations.

In 1983, wakame farming was deliberately presented into the North Atlantic in the seaside areas of Brittany and at first cultivated at three websites. Wakame growing is likewise being established in Northwest Spain.

Coming closer to house, in 2010, the New Zealand federal government approved commercial harvest and farming of wakame under specific conditions– basically, that it be harvested from a manufactured structure. There is still much work to be done in this space as a few of the New Zealand guidelines are outdated and complicated. The more we learn about wakame, the easier this ought to end up being.

Wakame as an ‘Invasive Types’– aka a ‘weed’!

Surprisingly, wakame has actually been considered a poisonous intrusive seaweed in countries aside from those where it is thought about to be native. It is thought that wakame was first presented to foreign waters through the ballast water of cargo ships from Asia, as the spores (gametophytes) included in the water can endure long-distance journeys.

In New Zealand, wakame remained in reality declared an undesirable organism in 2000 under the Biosecurity Act 1993. It was first found in Wellington Harbour in 1987 and it is thought it likely shown up in our water as hull fouling on shipping or fishing vessels from Asia. Wakame is now found throughout our marine environment in New Zealand, from Stewart Island to as far north as Karikari Peninsula. Even though it is an intrusive seaweed, in 2012 the federal government enabled the farming of wakame in Wellington, Marlborough and Banks Peninsula.

Wakame spreads in 2 methods: naturally, through the countless tiny spores released by each fertile organism, and through human activities, a lot of frequently by means of the hull of shipping vessels or marine farming equipment. It is an extremely effective and fertile types, which makes it a major invader. However, its effects are not well understood and can vary depending upon the location.

Is Wakame a Buddy or Enemy?

So as we discover wakame, do we see it as a good friend or opponent? The drawback of wakame is that it is intrusive and can alter the structure of ecosystems, specifically in locations where native seaweeds are missing. By forming a dense canopy, it shades the sub-canopy, and can affect the growth of slower-growing native seaweed species. For example, in New Zealand the native coralline algae which are necessary for paua (edible marine snail) settlement were partly displaced by wakame, resulting in decreased paua amounts.

Moreover, this intrusive seaweed can impact not only the biodiversity of plants, however likewise the fauna communities which are based on these phytogroups. Wakame can grow on reefs which use sanctuaries for fish, and gradually cause habitat loss of fishes that harp on the reefs. Studies carried out in the Nuevo Gulf showed that the removal of wakame from attacked sites resulted in a boost in the biodiversity at those locations.

Research suggests that the wakame seaweed or sea vegetable has the prospective to end up being a problem for marine farms because it increases labour and harvesting costs, due to fish cages, oyster racks, scallop bags and mussel ropes becoming covered. This development can likewise restrict water circulation through cages.

On the other hand, Pacific Harvest is proud to offer a tidy, fairly gathered wild wakame, which is largely healthy and useful for health. The accountable harvesting and appropriate drying of wakame, and subsequent use of it as an astonishingly helpful kitchen area pantry staple, indicates we rid our oceans of a ‘insect’, minimize costs of elimination, and contribute to a circular economy.

Wakame vs. Nori (Plus Other Seaweed)

Before we begin comparing some typical seaweeds, let’s answer this concern: Is seaweed a veggie?

Technically, seaweed is a form of algae, but seaweeds are often described as “sea vegetables” and typically treated as veggies for culinary purposes.

What eats seaweed? In addition to people, seaweed (in its natural environment) is commonly consumed by sea urchins, sea snails and plant-eating fish, such as the rabbit fish and parrot fish.

There are three primary varieties of seaweed frequently utilized as food: wakame, nori and kombu seaweed. However, these are certainly not the only edible seaweeds.

Other consumable choices, include

  • kelp (offered as fresh or dried kelp, as a supplement or in kelp powder form)
  • ogo seaweed (generally used in dried kind for poke recipes)
  • dulse seaweed (commonly utilized as fresh, raw dulse or dulse flakes)

While wakame is consumed fresh or dried, nori is primarily available in dried form. What is nori? It’s the most typical papery seaweed covering for sushi rolls, and unlike wakame, it is never soaked before serving.

Nori is best eaten wrapped around other items (like sushi) or toasted.

Kombu belongs to the kelp family, and like wakame, it’s a brown seaweed. Kombu is commonly used to make dashi, a delicious broth traditional to Japan and used to make miso soup.

Kombu and wakame have numerous overlapping health benefits and a similar flavor profile, however wakame is slightly sweeter. Both kombu and wakame are commonly used in seaweed salads and soups.

Kelp belongs to the brown algae class (Phaeophyceae), and kombu is a specific range of kelp that’s incredibly common in Japanese, Chinese and Korean food. It can be used in salads, soups and shakes, and there’s likewise kelp sushi.

As with “land vegetables,” sea vegetables also have distinct specific health advantages along with numerous overlapping advantages. In general, wakame, nori, kombu and kelp are all distinctly various yet share resemblances in their flavor profiles, uses and possible health benefits. [6]

Where to Purchase Wakame

A lot of Asian markets will have wakame, however other supermarkets might have wakame in the international aisle, or in a section dedicated to sushi, where the sushi rice, soy sauce, and nori are equipped. Another option is to discover it online. Wakame is most frequently found in little bags in its dried type, but the dry salt-preserved kind will remain in the refrigerated area, probably in an Asian market rather than the common supermarket. [7]

Negative Effects of Seaweed

The seaweed advantages and negative effects go together. A benefit to a single person may be a negative effects to another.

The high-fiber content in seaweed can assist digestion, however it can likewise cause digestive discomfort. Each gram of fiber adds up, and a number of servings of seaweed each day can easily press you over the suggested day-to-day allowance of fiber. Excessive fiber can cause bloating, gas and irregularity.

People with health problems associated with the thyroid ought to be specifically mindful of overconsuming seaweed because of its high iodine content. According to a March 2014 study published in Nature Reviews Endocrinology, excess iodine consumption does not have significant effects in the typical individual. However, people with particular danger elements connected to thyroid diseases– such as hypothyroidism and hyperthyroidism– may discover that too much iodine can impact their thyroid function and thyroid medications.

One side effect of consuming seaweed is associated with the environment rather than the actual food. The majority of the world’s seaweed is grown in China, however Korea and Japan are also major producers of seaweed. There is issue that seaweed grown on Japanese coasts is contaminated by radioactivity arising from the Fukushima nuclear accident in 2011. A January 2014 research study released in the Journal of Plant Research discovered polluted samples of algae. However, researchers do not encourage limiting your seaweed intake due to possible radioactive direct exposure.

Another adverse effects related to the environment is heavy metal exposure. According to a February 2018 study published in Scientific Reports, red seaweed consists of substantially greater levels of copper, nickel and other metals compared to brown seaweed. Though scientists found heavy metals like lead and mercury, they report the risk level is low. However, they recommend the regular monitoring of metals in seaweed.

When it comes to seaweed and seafood, inspecting the source of your items will assist avoid contamination. The health dangers are low, however getting to know where your food comes from is part of being a notified, health-conscious consumer. [8]


The correct amount of wakame consumption may differ from one individual to another. For the very best suggestions, you must speak with a nutritional expert, a dietitian or another health specialist.

Typically, most people who often eat wakame eat small amounts at a time, especially if the wakame is mixed in a soup or in sushi rolls. Be cautious not to consume excessive wakame, as it might result in negative effects, as mentioned above. [9]

The Bottom Line

Wakame is a highly nutritious, edible seaweed that can add a variety of minerals and vitamins to your diet for a low variety of calories.

It’s likewise been related to various health advantages, consisting of lower cholesterol levels, decreased high blood pressure, boosted weight loss and minimized blood sugar.
