Practice it Examples Notes & Tips 持続可能 in 30 Seconds

Explanation 持続可能 in your Level:

At the A1 level, learners are just beginning their journey into the Japanese language. The concept of 'sustainability' (持続可能 - jizokukanou) is generally too complex and abstract for this stage, both conceptually and grammatically. A1 learners focus on immediate, concrete vocabulary related to their daily lives, such as basic greetings, numbers, food, and simple objects. Instead of learning a complex four-kanji compound like 持続可能, an A1 student might learn simpler, related concepts. They might learn the word for 'nature' (自然 - shizen), 'tree' (木 - ki), or 'water' (水 - mizu). They might also learn basic verbs like 'to use' (使う - tsukau) or 'to protect' (守る - mamoru). If an A1 learner wants to express a basic idea related to the environment, they would use very simple sentence structures. For example, instead of saying 'We need sustainable practices,' they might say 'Nature is important' (自然は大切です - shizen wa taisetsu desu) or 'Please do not waste water' (水を大切にしてください - mizu o taisetsu ni shite kudasai). The grammatical structure required to use 持続可能 as a na-adjective modifying abstract nouns (like 'society' or 'development') is beyond the A1 curriculum. However, introducing the concept early through simple actions—like using an 'eco-bag' (エコバッグ)—lays the groundwork for understanding sustainability later. Teachers might introduce the katakana word 'エコ' (eko) as it is short, easy to pronounce, and highly visible in Japanese daily life, serving as a stepping stone toward the more formal 持続可能.

As learners progress to the A2 level, they begin to construct more complex sentences and expand their vocabulary to include topics beyond immediate personal needs, such as shopping, local geography, and basic societal concepts. While 持続可能 (jizokukanou) remains a challenging word, A2 learners might start encountering it passively, perhaps seeing the kanji on recycling bins or in simple public service announcements. At this stage, learners can understand the individual components of the word if broken down: they might know 持つ (motsu - to hold) and 続く (tsuzuku - to continue). A teacher might explain that combining these ideas means 'to keep going.' A2 learners can start using the katakana equivalent, サステナブル (sasutenaburu), which is increasingly common in everyday Japanese, especially in contexts like fashion or food. They can form sentences like 'This bag is eco-friendly' (このバッグはエコです) or 'I bought sustainable coffee' (サステナブルなコーヒーを買いました). They are also learning how to use na-adjectives, so they can practice the grammatical structure required for 持続可能, even if they primarily use simpler adjectives. The focus at A2 is on recognizing the context—knowing that when they see the green recycling symbols or hear about the SDGs on simple news programs, words like 持続可能 and エコ are likely being used. They learn to express basic opinions, such as 'Recycling is good for the environment' (リサイクルは環境にいいです), paving the way for more nuanced discussions in the future.

At the B1 level, learners cross the threshold into intermediate Japanese. They can handle a wide variety of topics, including current events, work, and general societal issues. It is at this stage that 持続可能 (jizokukanou) officially enters their active vocabulary. B1 learners are expected to understand and discuss the news, and since sustainability is a major global topic, this word is unavoidable. They learn how to use it correctly as a na-adjective to modify nouns, creating essential collocations like 持続可能な社会 (sustainable society) and 持続可能なエネルギー (sustainable energy). At this level, learners can express their opinions on environmental issues using more complex grammar, such as giving reasons (〜からです) or making suggestions (〜たほうがいいです). For example, a B1 student might say, 'To protect the earth, we should use sustainable energy' (地球を守るために、持続可能なエネルギーを使ったほうがいいです). They also begin to understand the distinction between the casual loanword サステナブル and the formal Japanese term 持続可能, knowing when to use which depending on the context (e.g., talking to a friend vs. writing a short essay). The introduction of the SDGs (持続可能な開発目標) in reading comprehension exercises is common at this level, challenging learners to read short articles about environmental initiatives and summarize the main points using this newly acquired vocabulary.

The B2 level is where learners achieve a high degree of fluency and can engage in detailed, nuanced discussions on complex, abstract topics. 持続可能 (jizokukanou) is a quintessential B2 vocabulary word. At this stage, learners are not just using the word in simple sentences; they are integrating it into complex arguments, debates, and professional or academic writing. They are comfortable using the noun form, 持続可能性 (jizokukanousei - sustainability), and the negative form, 持続不可能 (jizokufukanou - unsustainable). A B2 learner can read and understand newspaper editorials, corporate CSR reports, and government policy summaries regarding environmental and economic strategies. They can articulate the multifaceted nature of sustainability, discussing not just the environmental aspects, but also the economic and social dimensions. For instance, they can debate whether a specific corporate policy is truly sustainable or just 'greenwashing.' They use advanced grammar structures to express conditions, hypotheses, and logical conclusions. A typical B2 sentence might be: 'If we do not shift to a sustainable business model, long-term economic growth will be impossible' (持続可能なビジネスモデルに移行しなければ、長期的な経済成長は不可能です). They also master a wide range of collocations and related vocabulary, such as 環境保全 (environmental conservation), 再生可能エネルギー (renewable energy), and 資源の枯渇 (depletion of resources), allowing them to speak about sustainability with the precision and authority expected in professional environments.

At the C1 level, learners possess an advanced, near-native command of the language. Their use of 持続可能 (jizokukanou) goes beyond mere comprehension and standard usage; they can manipulate the language to express highly sophisticated, abstract, and critical thoughts. C1 learners engage with primary sources—academic papers, legal documents, and high-level political discourse—where this term is used in its most formal and rigorous contexts. They understand the subtle historical and cultural nuances of how sustainability is discussed in Japan, perhaps comparing modern SDGs with traditional Japanese concepts like 'Mottainai' or the Edo period's circular economy. At this level, learners can write comprehensive essays or deliver formal presentations on the macro-economic impacts of sustainable development goals. They use complex, formal grammar (such as 〜ざるを得ない, 〜にほかならない) to argue their points. A C1 learner might state: 'The transition to a sustainable society is not merely an environmental imperative, but an urgent economic necessity that dictates the survival of modern corporations' (持続可能な社会への移行は、単なる環境的要請にとどまらず、現代企業の存続を左右する焦眉の経済的課題にほかならない). They are also adept at recognizing and using highly specialized compound words and jargon related to sustainability, seamlessly integrating terms like 循環型社会 (circular economy) and 炭素中立 (carbon neutrality) into their discourse, demonstrating a profound mastery of both the language and the subject matter.

The C2 level represents mastery of the Japanese language, equivalent to that of a highly educated native speaker. At this pinnacle of language proficiency, the use of 持続可能 (jizokukanou) is effortless, precise, and deeply integrated into a vast web of related concepts. C2 learners can critique, deconstruct, and philosophize about the very concept of sustainability. They can read the most dense, technical literature—such as United Nations reports translated into Japanese or advanced treatises on environmental economics—without hesitation. They are capable of leading high-level negotiations, drafting corporate sustainability policies, or publishing academic research in Japanese. A C2 user understands the sociolinguistic implications of the word, recognizing when a politician might be using it as empty rhetoric versus when it is applied as a rigorous scientific metric. They can play with the language, perhaps creating novel compound words or using rhetorical devices to emphasize the urgency of sustainability. Their vocabulary is expansive, encompassing obscure or highly technical terms that even some native speakers might not know. A sentence at this level might read: 'In evaluating the efficacy of current environmental paradigms, one must critically assess whether the ostensible pursuit of sustainability merely perpetuates systemic inequalities under the guise of ecological stewardship' (現行の環境パラダイムの有効性を評価するにあたり、表向きの持続可能性の追求が、エコロジー管理という美名の下に構造的불平等を温存しているに過ぎないのではないかという点を、批判的に検証せねばならない). At C2, 持続可能 is a tool for profound intellectual engagement.

持続可能 in 30 Seconds

Means 'sustainable' or 'able to be maintained'.
Commonly used in environmental and economic contexts.
Functions grammatically as a na-adjective.
Key vocabulary for discussing the UN's SDGs.

The Japanese word 持続可能 (jizokukanou) is a highly significant and frequently used term in modern discourse, translating directly to 'sustainable' in English. To truly understand this word, we must break down its kanji components, explore its historical context, and examine its application in contemporary society. The word is composed of four distinct kanji characters: 持 (ji), meaning to hold or maintain; 続 (zoku), meaning to continue or persist; 可 (ka), meaning possible or acceptable; and 能 (nou), meaning ability or capacity. When combined, these characters form a powerful concept that goes beyond mere continuation. It implies an active, deliberate capability to maintain a certain state, process, or resource indefinitely without causing depletion, degradation, or collapse. In recent years, this term has become synonymous with environmental conservation, corporate responsibility, and global development goals. The concept of sustainability is not just an environmental buzzword in Japan; it is deeply embedded in traditional Japanese philosophies such as 'Mottainai' (a sense of regret concerning waste) and the harmonious coexistence with nature seen in Shinto beliefs. However, the modern usage of 持続可能 is heavily influenced by international frameworks, most notably the United Nations' Sustainable Development Goals (SDGs), which are widely referred to in Japan as 持続可能な開発目標 (jizokukanou na kaihatsu mokuhyou).

Etymological Breakdown: The term is a compound of 'jizoku' (continuation) and 'kanou' (possible), creating a clear, logical structure that makes its meaning immediately apparent to native speakers.

地球環境を守るためには、持続可能なエネルギーへの移行が不可欠です。

Understanding this word requires recognizing its dual nature: it is both a technical term used in policy documents and a common adjective used in everyday marketing. For instance, you might see it on packaging for eco-friendly products, in news reports about climate change, or in corporate mission statements. The versatility of 持続可能 allows it to modify various nouns, such as society (社会), agriculture (農業), and economic growth (経済成長).

Societal Impact: The adoption of this term reflects a societal shift towards long-term thinking, moving away from the rapid consumption models of the post-war economic boom.

この企業は持続可能なビジネスモデルを構築しています。

The concept also extends to personal lifestyle choices. Many Japanese consumers now actively seek out products that are labeled as 持続可能, indicating that the materials were sourced responsibly and that the manufacturing process minimized environmental impact. This shift in consumer behavior has forced companies to adapt, leading to a proliferation of the term in advertising and public relations.

Nuance in Usage: While often used interchangeably with 'eco-friendly' (エコ), 持続可能 carries a heavier, more systemic implication, focusing on long-term viability rather than just immediate environmental benefits.

私たちは持続可能な未来を子供たちに残す責任があります。

地域の資源を活用した持続可能な観光が注目されています。

そのプロジェクトは資金面で持続可能ではないと判断された。

In conclusion, mastering the word 持続可能 is essential for anyone looking to engage in meaningful conversations about the future of our planet, the economy, and society in Japanese. It represents a critical intersection of language, policy, and global awareness, making it a cornerstone vocabulary word for intermediate to advanced learners.

Using 持続可能 (jizokukanou) correctly in Japanese requires a solid understanding of its grammatical properties and the specific contexts in which it thrives. Primarily, 持続可能 functions as a na-adjective (形容動詞). This means that when it directly modifies a noun, it must be followed by the particle な (na). For example, 'sustainable society' becomes 持続可能な社会 (jizokukanou na shakai), and 'sustainable development' becomes 持続可能な開発 (jizokukanou na kaihatsu). This is the most common way you will encounter and use the word. It is essential to remember this 'na' connection, as omitting it is a frequent mistake among early learners.

Grammar Point: Na-Adjective: Always append 'な' when placing 持続可能 directly before a noun to describe it. Without 'な', the grammatical link is broken.

政府は持続可能な都市計画を発表した。

When used as an adverb to describe how an action is performed, the 'na' changes to 'ni' (に). For instance, if you want to say 'to grow sustainably', you would say 持続可能に成長する (jizokukanou ni seichou suru). This adverbial form is particularly useful in business and academic contexts where the manner of a process is being analyzed. Furthermore, 持続可能 can be used at the end of a sentence as a predicate. In formal contexts, it is followed by です (desu) or である (de aru). For example, 'This method is sustainable' translates to この方法は持続可能です (kono houhou wa jizokukanou desu).

Noun Form Conversion: Adding the suffix 性 (sei - nature/property) transforms the adjective into the abstract noun 持続可能性 (sustainability), used similarly to words like 可能性 (possibility).

企業の持続可能性が投資家から評価されている。

It is also crucial to understand the collocations—words that frequently pair with 持続可能. Common pairings include 開発 (kaihatsu - development), 社会 (shakai - society), エネルギー (enerugii - energy), 農業 (nougyou - agriculture), and 成長 (seichou - growth). Mastering these collocations will make your Japanese sound much more natural and fluent. When writing essays or giving presentations, using these established phrases demonstrates a high level of proficiency.

Negative Forms: To express 'unsustainable', it is more common to use the prefix 不 (fu) to create 持続不可能 (jizokufukanou) rather than conjugating the adjective negatively.

現在の消費ペースは明らかに持続可能ではない。

環境に配慮し、持続可能に資源を利用する。

そのシステムは長期的に見て持続可能ですか？

By practicing these various forms—the na-adjective modifier, the adverbial form, the noun form with 性, and the negative form—you will be well-equipped to use 持続可能 accurately and effectively in any Japanese language setting, from casual discussions about recycling to formal debates on global economic policies.

The presence of 持続可能 (jizokukanou) in modern Japanese society is ubiquitous, reflecting a global shift towards environmental consciousness and responsible governance. You will encounter this word across a wide spectrum of media, daily life, and professional environments. One of the most prominent places you will hear and see this word is in the news. Whether it is a broadcast on NHK or an article in the Yomiuri Shimbun, reports on climate change, international summits (like COP), and government policies frequently utilize the term. It is the standard vocabulary for discussing long-term environmental and economic strategies.

News and Media: Journalists use this term to describe policies, international agreements, and scientific reports regarding the environment and economy.

ニュースで持続可能な社会の実現に向けた議論が報道された。

Beyond the news, the corporate world has fully embraced the concept. If you work in Japan or interact with Japanese companies, you will find 持続可能 in CSR (Corporate Social Responsibility) reports, mission statements, and marketing materials. Companies are eager to present themselves as contributing to a 'sustainable society' (持続可能な社会). This is not just limited to heavy industries or energy sectors; even fashion brands, food manufacturers, and tech companies highlight their 'sustainable' practices, such as using recycled materials or reducing carbon footprints.

Corporate Marketing: Brands use the term to appeal to eco-conscious consumers, often printing it on packaging alongside recycling symbols.

この商品は持続可能な素材で作られています。

In everyday life, you might spot the word in supermarkets or department stores. Labels on seafood might indicate 'sustainable fishing' (持続可能な漁業), or coffee packaging might boast 'sustainably sourced beans'. Educational institutions also play a massive role in disseminating this vocabulary. Japanese schools integrate the SDGs into their curricula, meaning students are taught the importance of 持続可能な開発 (sustainable development) from a young age. This educational push ensures that the word is deeply ingrained in the cultural lexicon.

Everyday Consumerism: Shoppers encounter the word on product labels, guiding them toward ethical and environmentally friendly purchasing decisions.

大学で持続可能な環境学について学んでいます。

スーパーで持続可能な水産物の認証マークを見つけた。

私たちの目標は、持続可能な地域社会を作ることです。

Whether you are reading a high-level government white paper, listening to a corporate pitch, or simply buying groceries, 持続可能 is a word that bridges the gap between macro-level global goals and micro-level daily choices in Japan.

While 持続可能 (jizokukanou) is a highly useful word, learners of Japanese often make several common mistakes when trying to incorporate it into their vocabulary. These errors usually stem from grammatical misunderstandings, confusion with similar-sounding words, or misapplying the context. The most frequent grammatical mistake is forgetting that it is a na-adjective. Many learners try to connect it directly to a noun without the particle な (na), saying things like '持続可能社会' instead of the correct '持続可能な社会' (jizokukanou na shakai). While native speakers might understand the intent, it sounds grammatically incomplete and unnatural.

Missing Particle: Always remember the 'na' when modifying a noun. It is the glue that connects the adjective to the subject it describes.

❌ 持続可能開発 -> ⭕ 持続可能な開発

Another common pitfall is confusing 持続可能 with simpler terms like 長持ち (nagamochi - long-lasting) or 環境に優しい (kankyou ni yasashii - eco-friendly). While a sustainable product might be long-lasting and eco-friendly, 持続可能 implies a systemic, macro-level capability to be maintained without depleting resources. You wouldn't typically say 'This battery is sustainable' (この電池は持続可能だ) just because it lasts a long time; you would use 長持ちする. 持続可能 is reserved for systems, practices, societies, and resources.

Contextual Misuse: Avoid using 持続可能 for simple, everyday objects just because they are durable. Reserve it for systemic or environmental contexts.

❌ この靴は持続可能だ -> ⭕ この靴は長持ちする (But: この靴は持続可能な素材で作られている is correct)

Furthermore, learners sometimes struggle with the negative form. Instead of saying 持続可能じゃない (jizokukanou ja nai), which is grammatically acceptable but slightly clunky in formal writing, it is much more natural and professional to use the prefix 不 (fu) to create 持続不可能 (jizokufukanou - unsustainable). This sounds much more authoritative and is the standard usage in news and academic writing.

Formality Levels: Using 'ja nai' for negation is too casual for the contexts where 持続可能 is typically used. Opt for 'de wa nai' or 'fukanou'.

❌ その計画は持続可能じゃない -> ⭕ その計画は持続可能ではない / 持続不可能である

正しい使い方：持続可能なエネルギー源を開発する。

正しい使い方：企業の持続可能性を評価する。

By paying attention to the 'na' particle, understanding the systemic nuance of the word compared to simple durability, and using the correct negative forms, learners can avoid these common mistakes and sound highly proficient when discussing sustainability in Japanese.

When expanding your vocabulary around the concept of sustainability in Japanese, you will encounter several similar words and synonyms to 持続可能 (jizokukanou). Understanding the subtle differences between these terms will greatly enhance your ability to express complex environmental and economic ideas accurately. The most direct and modern synonym is the loanword サステナブル (sasutenaburu), derived directly from the English word 'sustainable'. In recent years, especially in marketing, fashion, and lifestyle media, サステナブル has become incredibly popular. It carries a trendy, modern, and accessible nuance compared to the more formal, academic-sounding 持続可能.

Loanword Equivalent: サステナブル (sasutenaburu) is used interchangeably in casual and commercial contexts, often appealing to younger demographics.

最近、サステナブルなファッションが流行している。（＝持続可能な）

Another related term is エコ (eko), short for ecology or eco-friendly. While related, エコ is much narrower in scope. It refers specifically to things that are good for the environment, like an eco-bag (エコバッグ) or eco-car (エコカー). 持続可能, on the other hand, encompasses not just environmental protection, but also economic viability and social equity. Therefore, while all 'eco' things aim to be sustainable, not all discussions of sustainability are limited to just 'eco' topics.

Narrower Scope: エコ (eko) focuses purely on environmental friendliness, lacking the economic and social dimensions of sustainability.

エコな生活を心がけることは、持続可能な社会への第一歩です。

You might also encounter the word 維持できる (iji dekiru), which means 'can be maintained'. This is a more literal, functional translation of 'sustainable' but lacks the specific environmental and global policy connotations that 持続可能 has acquired. If you are talking about maintaining a machine or a specific personal habit, 維持できる is appropriate. If you are talking about the future of the planet, 持続可能 is the required term.

Functional Maintenance: 維持できる (iji dekiru) is used for practical maintenance of states or objects, without the grander socio-environmental implications.

このペースで走り続けるのは維持できない。（Not 持続可能）

環境保全と経済成長の両立が持続可能な開発の鍵だ。

サステナビリティ（持続可能性）は現代のビジネスにおいて必須の概念です。

By distinguishing between the trendy サステナブル, the specific エコ, the functional 維持できる, and the comprehensive 持続可能, you can navigate Japanese discussions on the environment and future planning with precision and native-like nuance.

Sentence Patterns

How to Use It

nuance

While it translates to 'sustainable', in Japanese it carries a very strong, formal, and systemic nuance. It is less about personal endurance and entirely about ecological, economic, and societal viability.

colloquialisms

Rarely used colloquially. In casual speech, people say エコ (eko) or サステナブル (sasutenaburu).

Common Mistakes

Saying 持続可能社会 instead of 持続可能な社会 (forgetting the 'na').
Using it to describe personal physical endurance or stamina.
Confusing it with 長持ち (long-lasting) for simple everyday objects.
Pronouncing the 'zoku' as 'joku'. It is ji-zo-ku.
Writing 持続可能じゃない in formal essays instead of 持続不可能.

Tips

Don't forget the 'na'

The most common mistake is dropping the 'na' before a noun. Always practice saying 'jizokukanou NA shakai' to build muscle memory.

Learn the noun form

Add 'sei' (性) to the end to make 'sustainability' (持続可能性). This is crucial for reading business reports.

Use 'sasutenaburu' casually

If you are chatting with friends about a cool new eco-friendly cafe, use 'sasutenaburu' instead. It sounds much more natural in a casual setting.

Use 'fu' for the negative

In essays, write 持続不可能 (unsustainable) instead of 持続可能じゃない. It instantly elevates your writing to an advanced level.

Listen for the collocations

Train your ears to expect words like 'shakai' (society), 'kaihatsu' (development), or 'enerugii' (energy) immediately after hearing 'jizokukanou na'.

Look for the SDG badge

Notice the colorful circular badges Japanese businessmen wear on their lapels. They represent the SDGs (持続可能な開発目標). Mentioning this in a business meeting is a great icebreaker.

Break down the kanji

If you forget the meaning, look at the kanji: 持 (hold) + 続 (continue) + 可能 (possible). It literally means 'possible to hold and continue'.

Not for personal stamina

Never use this word to say 'I can't sustain my energy.' It sounds like you are a failing economic system. Use it for macro-level concepts.

Essential for interviews

If you are interviewing for a Japanese company, prepare a sentence about how you value their 持続可能な取り組み (sustainable initiatives).

Know the difference with 'eco'

Remember that 'eco' is just about the environment, while 'jizokukanou' includes the economy and society as well. Use the right word for the right scope.

Memorize It

Mnemonic

Imagine holding (持) a continuing (続) green earth, knowing it is possible (可能) to save it. Ji-zoku-ka-nou: Holding the continuation is possible!

Word Origin

Cultural Context

Highly professional. Using this word shows you are educated and aware of global issues. It is preferred over 'eco' in serious discussions.

Frequently Asked Questions

No, it is not natural to use 持続可能 for human stamina or energy. For a person, you would use words like 体力 (tairyoku - physical strength) or スタミナ (sutamina). 持続可能 is reserved for systems, societies, the environment, and business models.

They mean the exact same thing ('sustainable'), but 持続可能 is the formal, native Japanese term used in government, news, and academic contexts. サステナブル is a trendy English loanword used more in fashion, lifestyle marketing, and casual conversation.

If you are placing it directly before a noun to describe that noun (e.g., sustainable society), yes, you must use 'な' (持続可能な社会). If it is at the end of a sentence (e.g., This is sustainable), you use 'です' or 'だ' instead.

You add the suffix 性 (sei), which means 'nature' or 'property'. So, 持続可能性 (jizokukanousei) translates to 'sustainability'.

In formal writing and professional speaking, 持続不可能 (jizokufukanou - unsustainable) is preferred as it sounds more concise and academic. However, 持続可能ではない is grammatically correct and perfectly fine for intermediate learners to use.

SDGs stands for 持続可能な開発目標 (jizokukanou na kaihatsu mokuhyou), which translates literally to Sustainable Development Goals.
