養殖
養殖 in 30 Seconds
- Refers to aquaculture or the farming of fish, shellfish, and seaweed.
- Used to distinguish farmed seafood from wild-caught (tennen) varieties.
- Commonly found on food labels in Japanese supermarkets and menus.
- Crucial for discussions on sustainability and food technology in Japan.
The Japanese word 養殖 (ようしょく - yōshoku) is a specialized noun that refers to the systematic cultivation of aquatic life, including fish, shellfish, seaweed, and even pearls. In a country like Japan, where seafood is a cornerstone of the national diet, understanding the distinction between wild-caught and farmed products is essential for both daily life and professional culinary contexts. The term is composed of two kanji: 養 (yō), meaning to nurture, raise, or support, and 殖 (shoku), meaning to multiply, increase, or augment. Together, they describe the proactive human intervention in the lifecycle of aquatic organisms to ensure a stable food supply.
- Commercial Context
- You will most frequently encounter this word in supermarkets and at sushi restaurants. Labels will often specify whether a fish is tennen (天然 - wild) or yōshoku (養殖 - farmed). While wild fish often command a higher price due to perceived flavor depth and seasonal rarity, 養殖 products are praised for their consistent quality, year-round availability, and higher fat content, which is particularly prized in fish like salmon and yellowtail (buri).
近所のスーパーで、養殖のタイが安く売られていた。(At the local supermarket, farmed sea bream was being sold cheaply.)
- Technological Nuance
- In modern Japan, 養殖 is not just about nets in the ocean; it encompasses high-tech land-based systems (陸上養殖 - rikujō yōshoku) using filtered seawater or freshwater. This technology allows for the farming of species like pufferfish (fugu) in controlled environments, significantly reducing the risk of toxins. For a learner, using 養殖 demonstrates an awareness of the intersection between Japanese tradition (seafood culture) and modern industry.
日本は真珠の養殖技術で世界的に有名だ。(Japan is world-famous for its pearl cultivation technology.)
- Environmental Discussions
- In academic or news contexts, 養殖 is discussed in the framework of sustainability (持続可能性). As wild fish stocks dwindle due to overfishing, 養殖 is seen as a vital solution to global food security. However, it also brings up debates regarding water pollution and the use of chemicals, making it a common topic in JLPT N2 and N1 level reading comprehension passages.
海洋資源を守るために、養殖業の重要性が高まっている。(To protect marine resources, the importance of the aquaculture industry is increasing.)
In summary, 養殖 is a word that bridges the gap between the grocery store aisle and high-level environmental policy. It is a neutral, technical term that is indispensable for anyone living in or studying about Japan's relationship with the sea.
Using 養殖 correctly requires understanding its role as a noun that can also function as a modifier. It is most commonly paired with specific species of fish or followed by industry-related terms like 業 (gyō - industry) or 技術 (gijutsu - technology). Unlike 'farming' in English, which can apply to land animals, 養殖 is strictly reserved for the aquatic realm. For land animals, you would use 畜産 (chikusan - livestock) or 飼育 (shiiku - rearing).
このウナギは浜名湖で養殖されたものです。(This eel was farmed in Lake Hamana.)
- As a Compound Noun
- 養殖 is frequently combined with other nouns to create specific terms. For example, 養殖場 (yōshokujō) means a fish farm or hatchery. 養殖魚 (yōshokugyo) means farmed fish. In these cases, no particle is needed between 養殖 and the following noun.
彼は長年、真珠の養殖業に携わっている。(He has been involved in the pearl aquaculture industry for many years.)
- The 'No' Particle Usage
- When describing a specific product, use 'no' (の). For example: yōshoku no sake (farmed salmon). This distinguishes it clearly from tennen no sake (wild salmon). This is the most common way to use the word in a descriptive sense during conversation.
最近は、マグロの完全養殖が成功している。(Recently, the full-cycle aquaculture of tuna has been successful.)
- Passive Voice in Industry
- In technical reports, you often see the passive form yōshoku-sareteiru. For example: "This species is farmed in many parts of Asia." This emphasizes the process rather than the actor (the farmer).
この地域の川では、アユが養殖されています。(Sweetfish are being farmed in the rivers of this region.)
Whether you are reading a menu or a scientific journal, the structure remains consistent: [Species] + [Particle] + 養殖 or [養殖] + [Industry Term]. Mastering this will allow you to navigate Japan's complex food labeling system with ease.
The word 養殖 is ubiquitous in Japan, appearing in places ranging from the mundane to the highly academic. Because Japan is an island nation with a massive seafood industry, the methods by which that seafood is produced are a matter of daily public interest. Here is where you will encounter it most often.
- 1. Retail and Grocery Stores
- This is the primary location for most learners. On every pack of sashimi or whole fish, there is a mandatory label. You will see 養殖 (Farmed) or 天然 (Wild). Often, farmed fish is cheaper, but for certain species like Buri (Yellowtail), the farmed version is actually preferred by some for its high fat content (toro-like texture).
「このサーモン、養殖だけど脂がのっていて美味しいよ!」("This salmon is farmed, but it's fatty and delicious!")
- 2. Television News and Documentaries
- Japanese TV frequently features specials on regional revitalization. Often, a small village will try to save its economy by starting a yōshoku project for a rare fish. You will hear phrases like yōshoku no chōsen (the challenge of aquaculture) or chiiki-okoshi no yōshoku (aquaculture for regional promotion).
ニュース:温暖化の影響で、養殖ワカメの収穫が減っています。(News: Due to the effects of global warming, the harvest of farmed seaweed is decreasing.)
- 3. High-End Sushi Restaurants
- In omakase settings, the chef might explain the origin of the fish. While high-end chefs usually pride themselves on tennen (wild) fish, they may mention kanzen yōshoku (full-cycle farmed) tuna to highlight technological progress or sustainability. It's a point of conversation regarding the future of Japanese cuisine.
レストランのメニュー:養殖トラフグのコース料理 (Course meal of farmed Tiger Pufferfish).
- 4. School Textbooks and Exams
- For those taking the JLPT or EJU, 養殖 is a standard vocabulary item in the 'Environment' or 'Economy' sections. It is often used in graphs comparing wild vs. farmed production over the decades. Understanding the kanji and its context is crucial for answering data-interpretation questions.
In summary, whether you are buying dinner, watching a documentary, or studying for a proficiency test, 養殖 is a keyword that reflects Japan's deep-rooted connection to the sea and its forward-looking approach to food technology.
While 養殖 (yōshoku) is a straightforward term, English speakers often make mistakes due to the nuances of 'farming' in English and the existence of Japanese homophones. Here are the most common pitfalls to avoid.
- 1. Homophone Confusion: 養殖 vs. 洋食
- This is the #1 mistake. 養殖 (yōshoku) means aquaculture. 洋食 (yōshoku) means Western-style Japanese food (like curry or croquettes). To the untrained ear, they sound identical. However, in 養殖, the 'yō' is a long vowel (よう), whereas in some contexts, people might mispronounce the short 'yo' of 洋食. Context is key: if you are at a fish market, it's aquaculture; if you are at a cafe, it's Western food.
❌ 洋食の魚を食べます。(Eating Western-style fish - grammatically okay but often a mistake for farmed fish.)
✅ 養殖の魚を食べます。(Eating farmed fish.)
- 2. Overextending the Meaning to Land Animals
- In English, we 'farm' cows and we 'farm' salmon. In Japanese, 養殖 is only for aquatic life. Using it for cows, pigs, or chickens is a major error. For land animals, use 飼育 (shiiku) or 畜産 (chikusan).
- 3. Confusing with 栽培 (Saibai)
- 栽培 (saibai) is used for plants (vegetables, fruits, rice). While seaweed is technically a plant-like organism, it is usually grouped under 養殖 because it happens in the water. However, if you are talking about tomatoes or mushrooms, use 栽培. Using 養殖 for land plants is incorrect.
❌ トマトの養殖 (Aquaculture of tomatoes)
✅ トマトの栽培 (Cultivation of tomatoes)
- 4. Misusing the Kanji 殖 (Shoku)
- The second kanji 殖 is relatively rare outside of this word and 繁殖 (hanshoku - breeding). Students often confuse it with 植 (shoku - to plant). While they sound the same, 植 is for land plants (like in shokubutsu). 殖 implies multiplying or increasing a population, which is more appropriate for biological breeding in aquaculture.
By keeping these distinctions in mind—especially the aquatic-only rule and the homophone with 'Western food'—you will use 養殖 like a native speaker and avoid confusing your listeners.
To truly master the concept of aquaculture in Japanese, it's helpful to understand the surrounding vocabulary. There are several words that overlap with 養殖, but each has a distinct usage and register.
- 養殖 (Yōshoku) vs. 栽培漁業 (Saibai Gyogyō)
- While 養殖 refers to raising fish in a confined space until they are ready for market, 栽培漁業 (sea ranching) involves hatching fish, raising them to a certain size, and then releasing them into the open ocean to be caught later. It's a 'hybrid' between farming and wild fishing.
この県では、ヒラメの栽培漁業に力を入れている。(This prefecture is focusing on sea ranching for flounder.)
- 養殖 (Yōshoku) vs. 飼育 (Shiiku)
- 飼育 is the general word for raising or breeding animals, including pets or livestock. While you could use it for fish in an aquarium, 養殖 is the specific professional term for food production. If you have a goldfish at home, you are doing shiiku, not yōshoku.
家で金魚を飼育しています。(I am keeping goldfish at home.)
- 養殖 (Yōshoku) vs. 繁殖 (Hanshoku)
- 繁殖 refers specifically to the biological process of reproduction and breeding. In an aquaculture setting, 繁殖 is one part of the 養殖 process. You might hear about the hanshoku of a rare species being difficult, which is the technical reason why yōshoku might be expensive.
絶滅危惧種の繁殖に成功した。(Successfully bred an endangered species.)
- Advanced Term: 孵化 (Fuka)
- In the context of fish farming, you will also see 孵化 (hatching). A fukajō is a hatchery. This is where the 養殖 process begins. Understanding these related terms will help you read more complex articles about the Japanese fishing industry.
By distinguishing between these terms, you can speak more precisely about biology, industry, and environmental conservation in Japanese.
How Formal Is It?
Fun Fact
While aquaculture feels like a modern technology, Japan has been 'farming' oysters and seaweed since the Edo period (1603–1867). The word 養殖 became standardized in the late 19th century as Japan modernized its industrial terminology.
Pronunciation Guide
- Pronouncing it as 'yoshoku' (short o), which means Western food (洋食).
- Confusing the pitch accent with 'yōshoku' (Western food), though they are often both Heiban, context is the main differentiator.
- Mispronouncing 'shoku' as 'shaku'.
- Failing to elongate the 'yō' sound.
- Over-emphasizing the final 'u'.
Difficulty Rating
The kanji are intermediate level (N3/N2). 養 is common, but 殖 is rarer.
The kanji 殖 has many strokes and is easy to miswrite as 植.
Pronunciation is easy, but must distinguish from 'Western food'.
Context is required to distinguish from 'yoshoku' (Western food).

How to Use It
High in food, economic, and environmental contexts in Japan.
-
Using 'yōshoku' for vegetables.
→
栽培 (saibai)
養殖 is strictly for aquatic organisms. For land plants, 'saibai' is the correct term.
-
Pronouncing it the same as 'Western food'.
→
Yōshoku (long o)
洋食 (Western food) has a short 'yo' in some dialects or is simply written differently, but 養殖 must have the long 'ō' sound.
-
Using 'yōshoku' for pets.
→
飼育 (shiiku)
養殖 implies industrial farming for food or resources. For a pet fish at home, 'shiiku' (rearing) is appropriate.
-
Confusing 殖 with 植 in writing.
→
養殖
植 (shoku) is for planting trees/plants. 殖 (shoku) is for multiplying/breeding. They are different kanji.
-
Thinking 'yōshoku' is always lower quality.
→
N/A
In modern Japan, some 'yōshoku' fish are premium brands and can be more expensive/delicious than wild ones. Don't assume it's 'cheap' only.
Tips
Look for the Kanji
When at a Japanese supermarket, look for the character 養 (yō) on the label. It's usually in a small box. If you see it, the fish is farmed. If you see 天 (ten), it's wild. This helps you understand the price difference immediately.
Long Vowel Alert
The difference between 'aquaculture' (yōshoku) and 'Western food' (yoshoku) is just the length of the 'o'. Practice saying 'Yoo-shoku' for the fish farm. Context usually saves you, but clear vowels make you sound more fluent.
Use with 'no'
To describe a fish, always use 'yōshoku no' + [Fish Name]. For example, 'yōshoku no sake' (farmed salmon). This is the most natural way to use the word in daily conversation.
Kindai Maguro
If you want to impress Japanese friends, mention 'Kindai Maguro.' It's the famous farmed tuna from Kinki University. It's a great conversation starter about technology and food in Japan.
Don't use for Cows
Remember that 養殖 is only for things that live in water. If you want to talk about farming cows or pigs, use 畜産 (chikusan). Using 養殖 for land animals is a common and funny mistake for beginners.
Kanji Breakdown
The first kanji 養 (nurture) is the same as in 栄養 (eiyō - nutrition). The second 殖 (multiply) is the same as in 繁殖 (hanshoku - breeding). Linking these words helps you remember the meaning of 養殖.
Contextual Clues
In a sushi restaurant, if the chef says 'tennen,' he is bragging. If he doesn't say anything, or says 'yōshoku,' he is being honest about the source. Listen for these keywords to understand the quality of the meal.
The 'Natural' Joke
Japanese people use 'tennen' to describe someone who is naturally airheaded. Sometimes they joke that someone is 'yōshoku' (farmed/fake airhead), meaning they are acting ditzy on purpose. Use this carefully with friends!
JLPT Context
For the JLPT, 養殖 usually appears in reading passages about the environment or sustainable development. Focus on how it's contrasted with 'overfishing' (ran-kaku) and 'resource depletion' (shigen no kokatsu).
Fat Content
Farmed fish (yōshoku) is generally fattier. If you are making a dish that needs a rich, buttery flavor, 養殖 is actually a better choice than the leaner 天然 (wild) version.
Memorize It
Mnemonic
Think of 'Yo!' (養) as calling out to the fish you are raising, and 'Shoku' (殖) as the 'Shock' of how many more fish you have now. 'Yo! Shocking amount of fish farmed!'
Visual Association
Imagine a large circular net in the blue ocean filled with jumping salmon. On the net, there is a big label with the kanji 養殖.
Word Web
Challenge
Go to a Japanese grocery store (or look at photos online) and find the word 養殖 on a seafood label. Compare its price to a label that says 天然.
Word Origin
The term is a Sino-Japanese compound (Kango). The first character '養' (yō) dates back to ancient Chinese, representing a hand holding a whip over a sheep, originally meaning to 'graze' or 'nurture'. The second character '殖' (shoku) combines 'bone' and 'increase', originally referring to the multiplication of living things or wealth.
Original meaning: To nurture and multiply living resources.
Sino-Japanese (Kango)Cultural Context
There are ongoing debates about the environmental impact of 養殖, such as waste and antibiotic use. Be mindful of this when discussing the industry in environmental contexts.
In English, we often use 'farmed' or 'aquaculture.' 'Farmed' can sound negative to some health-conscious consumers, but in Japan, 'yōshoku' is often marketed as 'safe' and 'consistent.'

Frequently Asked Questions
10 questionsYes, 'yōshoku' fish in Japan is subject to strict safety regulations regarding feed and medicine. In fact, some farmed fish like 'fugu' (pufferfish) are considered safer because their diet is controlled to prevent toxin buildup. Many people prefer 'yōshoku' for its consistent quality and safety.
'Yōshoku' (養殖) means farmed, and 'tennen' (天然) means wild-caught. 'Tennen' is often more expensive and considered a seasonal delicacy, while 'yōshoku' is available year-round and often has a higher fat content, which many find delicious in sushi.
Yes, 'yōshoku' is commonly used for seaweed like 'wakame' or 'nori.' While seaweed is a plant, because it is grown in the water as part of the marine industry, 'yōshoku' is the standard term rather than 'saibai' (which is for land plants).
The first syllable 'yō' is long, like 'yo' in 'yo-yo'. The second part 'shoku' is short. Be careful not to say 'yoshoku' (short 'yo'), as that means 'Western food.' Think: 'Yoo-sho-ku'.
As wild fish populations decline due to overfishing, 'yōshoku' provides a way to meet the global demand for seafood without depleting natural ocean resources. However, it must be managed carefully to avoid polluting the surrounding water.
'Kanzen yōshoku' (完全養殖) or 'full-cycle aquaculture' means raising fish from eggs produced by farmed parents. This is a major breakthrough because it means the farm doesn't need to catch any wild juvenile fish to start the process, making it truly sustainable.
The most common ones are salmon (sake), sea bream (tai), yellowtail (buri/hamachi), eel (unagi), and various types of shellfish like oysters (kaki). Farmed bluefin tuna (maguro) is also becoming increasingly common.
Yes, 'yōshoku' is the direct equivalent of 'aquaculture.' It covers fish, crustaceans, mollusks, and aquatic plants. It's the most professional and common term used in Japan for this industry.
Not necessarily. 'Yōshoku' fish often have more Omega-3 fatty acids because of their controlled diet. However, some people prefer 'tennen' fish because they have a leaner texture and are perceived as more 'natural.' It depends on your personal health goals and taste preferences.
Yes, 'shinju no yōshoku' (pearl aquaculture) is a very common phrase. Japan is world-famous for this, especially the Akoya pearls from Mie Prefecture. It follows the same principle of human-managed growth.

Summary
養殖 (yōshoku) is the Japanese term for aquaculture. It is vital for understanding food origins in Japan, where 'yōshoku' (farmed) and 'tennen' (wild) are the two primary categories for seafood. Example: 養殖のサケ (farmed salmon).
- Refers to aquaculture or the farming of fish, shellfish, and seaweed.
- Used to distinguish farmed seafood from wild-caught (tennen) varieties.
- Commonly found on food labels in Japanese supermarkets and menus.
- Crucial for discussions on sustainability and food technology in Japan.
Look for the Kanji
When at a Japanese supermarket, look for the character 養 (yō) on the label. It's usually in a small box. If you see it, the fish is farmed. If you see 天 (ten), it's wild. This helps you understand the price difference immediately.
Long Vowel Alert
The difference between 'aquaculture' (yōshoku) and 'Western food' (yoshoku) is just the length of the 'o'. Practice saying 'Yoo-shoku' for the fish farm. Context usually saves you, but clear vowels make you sound more fluent.
Use with 'no'
To describe a fish, always use 'yōshoku no' + [Fish Name]. For example, 'yōshoku no sake' (farmed salmon). This is the most natural way to use the word in daily conversation.
Kindai Maguro
If you want to impress Japanese friends, mention 'Kindai Maguro.' It's the famous farmed tuna from Kinki University. It's a great conversation starter about technology and food in Japan.
