hatten saseru
Practícalo Ejemplos Notas y consejos 発展させる en 30 segundos
Explicación 発展させる in your Level:
At the A1 level, '発展させる' (hatten saseru) is quite advanced. However, you can think of it as 'making something bigger and better.' Imagine you have a small toy city, and you want to make it a 'big city.' That action of 'making it grow' is what this word describes. It is like the word 'make' combined with 'grow.' You won't use this word often in basic greetings, but you might see it in simple stories about a king making his country strong or a person making their small shop big. Just remember: it's about someone *doing* the growing to something else. A1 learners should focus on the idea that this word is for 'big things' like countries or businesses, not for small things like growing a plant (which is 'sodateru').

At the A2 level, you can start to understand '発展させる' as a formal way to say 'to develop.' You might use it when talking about your hobbies or a small project. For example, 'I want to develop my Japanese study into a job' (Nihongo no benkyou o shigoto ni hatten sase tai). It's a useful word for expressing goals. Notice the structure: [Something] を [New State] に 発展させる. This 'ni' tells us what the thing becomes. You might hear it in simple news clips about a city building new parks to 'develop' the area. It is more formal than 'ookiku suru' (to make big) and shows that you are talking about something more serious than just size.

For B1 learners, '発展させる' is a key vocabulary item for discussing social issues, business, and personal goals. At this level, you should be able to distinguish it from 'hatten suru' (to develop - intransitive). You will use 'hatten saseru' when you are the subject taking action to improve a situation. For example, 'The company developed a new market' (Kaisha wa atarashii ichiba o hatten saseta). It is also used for abstract things like 'developing an argument' in an essay. You should be comfortable using it in the 'te-form' to explain how one action leads to the development of something else. This word is essential for passing the JLPT N3 level and for participating in workplace discussions.
At the B2 level, you should master the nuances of '発展させる' compared to 'kaihatsu suru' (to develop/create) and 'seichou saseru' (to grow). You will encounter this word in complex texts about economics, sociology, and history. It describes the intentional advancement of civilizations or the evolution of complex systems. You should also be able to use it in the potential form ('hatten saserareru') and understand it in formal speeches or editorials. For instance, 'How can we develop our traditional culture in the modern age?' (Dentou bunka o gendai ni dou hatten saseru beki ka?). It carries a sense of responsibility and strategic planning. You will also see it used in scientific contexts regarding the development of theories.

At the C1 level, '発展させる' is used to discuss high-level conceptual evolution and systemic transformation. You will use it to describe how one historical event 'developed' into a major movement, or how a philosophical idea was 'developed' by later thinkers. The word is often found in academic papers and high-level business strategy documents. You should be able to use it with sophisticated adverbs and in complex grammatical structures, such as 'hatten saseru koto ni yotte' (by developing...). At this level, you understand that 'hatten saseru' implies not just growth, but a qualitative leap in complexity or efficiency. It is a word used to frame progress within a larger historical or social narrative.

For C2 learners, '発展させる' is a precise tool for articulating the dynamics of change and agency. You will analyze how different actors (states, corporations, individuals) 'develop' paradigms, infrastructures, and global networks. You can distinguish the subtle stylistic differences between 'hatten saseru' and more obscure synonyms like 'shinkou saseru' (to promote/advance). In professional or academic writing, you use this verb to precisely attribute the cause of progress. It is used in discussions about 'sustainable development' (jizoku kanou na hatten) and the ethics of 'developing' certain technologies. At this level, the word is not just a verb but a conceptual pillar for discussing the trajectory of human endeavor.

発展させる en 30 segundos

  • A formal verb meaning 'to develop' or 'to cause to grow'.
  • Used for systems, economies, ideas, and organizations.
  • The causative form of 'hatten suru' (to develop/expand).
  • Essential for business Japanese and formal writing contexts.

The Japanese verb 発展させる (hatten saseru) is a transitive verb that translates to "to develop," "to expand," or "to cause to grow." It is the causative form of the intransitive verb 発展する (hatten suru). In Japanese linguistics, the causative construction is used to indicate that an agent is initiating or facilitating a process. When you use 発展させる, you are emphasizing that a specific person, organization, or factor is the driving force behind the progress or expansion of something else. This word is highly versatile, appearing in contexts ranging from urban planning and economic policy to personal skill development and the elaboration of ideas.

Semantic Range
It covers physical growth (cities), abstract growth (theories), and systemic growth (economies).

One of the most common uses is in business and economics. You will frequently hear leaders talk about how they intend to hatten saseru their company or the local economy. It implies a deliberate, strategic effort to move from a current state to a more advanced, complex, or successful state. Unlike simple growth verbs like ookiku suru (to make big), 発展させる carries a nuance of sophistication and qualitative improvement, not just quantitative increase.

新しい技術を使って、この産業をさらに発展させる必要があります。
(We need to use new technology to further develop this industry.)

In academic or creative contexts, this verb is used when taking a basic concept and building upon it. For example, a scientist might hatten saseru a hypothesis into a full-fledged theory through rigorous testing. A writer might hatten saseru a short story into a novel. It suggests a process of maturation and refinement. It is also used in social contexts, such as developing a relationship or a conversation, though it remains slightly more formal than everyday colloquialisms.

Transitivity Note
Remember that this takes the particle 'o' (を) because you are acting upon an object to make it develop.

彼は自分のアイデアをビジネスに発展させた。
(He developed his idea into a business.)

Finally, the word is often paired with adverbs like yori (more) or kyuugeki ni (rapidly) to describe the pace or scale of the development. Because it is a causative construction of a Sino-Japanese (Kango) word, it feels more authoritative than native Japanese (Wago) equivalents like nobasu. In summary, use 発展させる when you are the architect of growth, whether that growth is a city, a company, or a complex thought.

Using 発展させる correctly requires understanding its grammatical structure as a causative verb. Since it is the causative of 発展する, it follows the pattern: [Agent] + が/は + [Object] + を + 発展させる. This structure clearly identifies who is responsible for the growth. In many formal documents, the agent might be omitted if it is understood to be the speaker or the organization they represent.

Grammatical Pattern
[Target] を [Result] に 発展させる (To develop [Target] into [Result])

A common construction involves the particle ni (に) to show the end state of the development. For example, if you are developing a small shop into a nationwide chain, you would say "shop o chain ni hatten saseru." This 'into' nuance is crucial for describing transformation. It is not just about making something bigger; it is about evolving it into a new form or status.

政府は地方の経済を発展させるための新しい政策を打ち出した。
(The government launched a new policy to develop the local economy.)

The verb is also frequently used in the potential form hatten saserareru (can develop) or the passive-causative hatten saserareru (be made to develop), though the latter is rare. More common is the use of the te-form to link actions: "We will invest capital and develop the business" (shihon o touki shite, jigyou o hatten saseru). This shows a logical sequence of cause and effect.

In interpersonal communication, you might hear it in a more metaphorical sense. For instance, "Let's develop this conversation further" (kono hanashi o motto hatten saseyou). Here, it implies moving from small talk to a deeper discussion or a concrete plan. It shows intent and directionality. In writing, it is often found in the concluding sections of reports where future goals are discussed, emphasizing the proactive stance of the author.

私たちはこのプロジェクトをグローバルな規模に発展させるつもりです。
(We intend to develop this project to a global scale.)

Common Collocations
文化を発展させる (develop culture), 国を発展させる (develop a country), 議論を発展させる (develop an argument).

When using it in the negative form, hatten sase nai, it often implies a failure to capitalize on an opportunity or a lack of resources to foster growth. For example, "Without funding, we cannot develop the research" (shikin ga nakereba, kenkyuu o hatten sase rarenai). This highlights the conditional nature of the causative action.

You will encounter 発展させる most frequently in formal environments. If you watch NHK News or read a Japanese newspaper like the Asahi Shimbun, this word appears almost daily. It is the standard term for discussing national growth, technological advancement, and international relations. It conveys a sense of officialdom and serious intent.

News Context
Used when reporting on GDP growth, urban redevelopment projects, or diplomatic ties being 'developed' into partnerships.

In the corporate world, this word is a favorite in 'Mission Statements' and 'Annual Reports.' CEOs use it to describe their vision for the future. During a job interview, a candidate might use it to describe how they want to 'develop' their skills or how they can 'develop' the company's sales channels. It marks the speaker as someone who is forward-thinking and results-oriented.

わが社は、持続可能な社会を発展させるために貢献します。
(Our company contributes to developing a sustainable society.)

Academic lectures and scientific documentaries also rely heavily on this term. Whether it's discussing how life evolved (though shinka is more specific for biological evolution, hatten is used for the development of civilizations) or how a mathematical proof was developed, 発展させる provides the necessary level of formal description. It bridges the gap between 'starting something' and 'perfecting something.'

Another interesting place to hear this is in the context of games and simulations. Strategy games (like Civilization or SimCity) often use hatten saseru in their tutorials or menus when referring to upgrading buildings or expanding your empire. It gives the player a sense of agency—you are the one making the city grow.

この村を大きな町に発展させるのが私の夢です。
(It is my dream to develop this village into a large town.)

Cultural Nuance
In Japanese culture, 'development' is often viewed as a collective effort. Even if one person says they will 'develop' something, it often implies they will lead a team to do so.

Lastly, in educational settings, teachers encourage students to hatten saseru their ideas during group work. It moves beyond just having an idea to exploring its implications and applications. It is a word of encouragement for intellectual curiosity and thoroughness.

One of the most frequent errors learners make is confusing 発展させる (hatten saseru) with its intransitive counterpart 発展する (hatten suru). Remember: hatten suru means "something develops" (e.g., the city develops), while hatten saseru means "someone develops something" (e.g., the mayor develops the city). Using the wrong one can change the meaning from a natural process to a deliberate action, or vice-versa.

Transitivity Error
Wrong: 経済が発展させた (The economy developed [something]).
Right: 経済が発展した (The economy developed).

Another mistake is using 発展させる for physical objects that are being 'built' or 'created' rather than 'developed.' For example, you don't 'develop' a house in the sense of building it; you use tateru (to build). Hatten saseru implies a process of improvement or expansion of an existing entity or a complex system. It is about the *evolution* of the thing, not its initial construction.

Incorrect: 家を発展させる。
Correct: 家を建てる (Build a house) or 庭を整える (Fix up the garden).

Learners also sometimes confuse it with kaihatsu suru (開発する). While both can mean 'develop,' kaihatsu suru is specifically for developing resources, software, or land (like 'R&D'). Hatten saseru is more about the ongoing growth and advancement of a state or concept. You kaihatsu a new app, but you hatten saseru the digital economy of a country.

Overusing the word in casual conversation can also sound stiff. If you are just talking about making a party more exciting, moriageru is better. Hatten saseru sounds like you are writing a white paper. Avoid it when a simpler, more emotional verb would suffice.

Too formal: パーティーを発展させる。
Natural: パーティーを盛り上げる。

The 'Ni' Particle Mistake
Forgetting to use 'ni' when describing the transformation. If you develop A into B, B must be followed by 'ni'.

Lastly, ensure the subject is capable of the action. Usually, an agent (person/group) or a catalyst (new technology) is the subject. If you say "The weather developed the city," it sounds illogical in Japanese unless the weather is a metaphorical personified force.

Japanese has several words for 'develop' or 'grow,' and choosing the right one is key to sounding natural. 発展させる is the go-to for systematic and qualitative advancement. Let's compare it with its closest relatives.

発展させる vs. 成長させる (Seichou saseru)
Seichou saseru is primarily for biological growth (plants, children) or the growth of a company's scale. Hatten saseru is for the advancement of systems, civilizations, or ideas. You 'grow' a child, but you 'develop' a society.
発展させる vs. 開発する (Kaihatsu suru)
Kaihatsu suru is 'to develop' in the sense of creating something new from scratch or exploiting resources (e.g., land development, software development). Hatten saseru is about taking something that exists and making it better or more complex.

新薬を開発する (Develop a new drug) vs. 医療技術を発展させる (Develop/advance medical technology).

Another alternative is 進歩させる (Shinpo saseru). This specifically means 'to make progress' or 'to advance.' It is often used for skills or technology where there is a clear linear path of improvement. 発展させる is broader and can involve expanding in multiple directions, not just moving forward.

Comparison Summary
1. 発展させる: Systems, economies, sophisticated ideas (Transitive).
2. 成長させる: Living things, company size (Transitive).
3. 開発する: New products, land, resources (Transitive).
4. 普及させる (Fukyuu saseru): To spread something (like a new custom or technology) among the public.

When talking about 'developing' a story or plot, tenkai saseru (展開させる) is often used to describe how events unfold. If you want to say 'develop' in the sense of 'cultivating' a skill or quality, yashinau (養う) is a beautiful alternative that implies nurturing over a long period. Understanding these nuances will make your Japanese sound far more sophisticated and precise.

How Formal Is It?

Dato curioso

The character 展 (ten) originally depicted a person lying down and stretching their legs, which evolved to mean 'to expand' or 'to spread out'. Adding 'saseru' turns this natural expansion into a deliberate act of management.

Guía de pronunciación

UK hat.teɴ sa.se.ɾɯ
US hat.teɴ sa.se.ɾɯ
Japanese is pitch-accented. In 'hatten', the pitch usually drops after 'hat'. 'Saseru' is typically flat or follows the verb's standard conjugation pitch.

Katten (selfishness) Datten (escape) Watten (splitting) Matteseru (making someone wait - informal/slangy) Misaseru (making someone look) Kakaseru (making someone write) Yomaseru (making someone read) Tateseru (making someone stand)
Errores comunes
  • Pronouncing 'hatten' as 'haten' (missing the double 't').
  • Using an English 'r' for 'ru' instead of the Japanese tapped 'r' (like a quick 'd').
  • Stress-accenting one syllable like 'HAT-ten' instead of using pitch.
  • Nasalizing the 'n' too much like a French 'en'.
  • Pronouncing 'saseru' as 'say-seru' (it should be 'sah-seh-roo').

Cómo usarlo

frequency

High in news, business, and academics. Medium in daily life.

Errores comunes
  • 経済が発展させた。 → 経済が発展した。 (or) 政府が経済を発展させた。

    You cannot use the causative 'saseru' with the object as the subject. If the economy is growing, use 'hatten shita'. If the government is making it grow, use 'hatten saseta'.

  • 子供を発展させる。 → 子供を成長させる / 育てる。

    'Hatten saseru' is for abstract systems, not biological beings. Using it for a child sounds like you are treating them like an economy.

  • 家を発展させる。 → 家を建てる / 改築する。

    'Hatten saseru' is not for physical construction. Use 'tateru' (build) or 'kaichiku' (renovate).

  • 写真を発展させる。 → 写真を現像する。

    This is a direct translation error from English 'develop a photo'. In Japanese, photo development is 'genzou'.

  • 趣味を発展した。 → 趣味を発展させた。

    If you are the one doing the developing, you must use the transitive 'saseru' and the particle 'o'.

Consejos

Causative Nuance

Remember that 'saseru' is the causative. It emphasizes that you are the *cause* of the growth. This makes it a strong word for leaders and creators.

Kango vs. Wago

'Hatten saseru' is Kango (Chinese-origin). It sounds more intellectual than native Japanese words like 'nobasu'. Use it in professional settings.

Business Essential

This is a top-tier word for business presentations. Use it when talking about market expansion or project growth.

Resultative 'Ni'

Always use 'ni' when you want to say 'develop into'. It helps the reader see the transformation clearly.

Not for Plants

Don't use it for gardening. 'Sodateru' is for plants. 'Hatten saseru' is for systems.

Kanji Breakdown

Hatsu (Start) + Ten (Unfold). Think of it as 'Starting to Unfold' something to its full potential.

Pitch Accent

Keep the 'sa-se-ru' part relatively flat and connected to the 'hatten' to sound natural.

News Keyword

When you hear 'hatten' on the news, listen for 'saseru' vs 'suru' to know if the government is taking credit for it.

The 'Ten' Rule

Development makes things a '10 out of 10'. Hatten saseru gets you to that 10.

National Growth

Understand that 'hatten' is a very positive word in Japan, associated with the post-war miracle.

Memorízalo

Mnemotecnia

Think of a 'HAT' that you are 'TEN'ding to. You put effort into the 'HAT' to make it bigger and better—you 'HATTEN' it! Then you 'SASERU' (say-say-roo) to show you are the boss making it happen.

Asociación visual

Imagine a small sprout inside a glass box. You (the agent) are adding water and light (the action) to make the plant 'Hatten saseru' until it breaks out of the box into a tree.

Word Web

Business City Economy Idea Growth Causative Transitive Progress

Desafío

Try to use 'hatten saseru' in three different contexts: one for a business, one for a conversation, and one for a personal skill.

Origen de la palabra

Comes from the Chinese characters 発 (hatsu - to start/emit) and 展 (ten - to unfold/expand). The word 'Hatten' entered Japanese through Buddhist texts and later became a general term for progress. 'Saseru' is the auxiliary causative verb added to the noun-verb 'Hatten suru'.

Significado original: To unfold or spread out something that was previously folded or small.

Sino-Japanese (Kango) roots with a Japanese auxiliary verb.

Contexto cultural

Generally a very positive word. No specific taboos, but avoid using it for 'developing' a disease or a negative habit; use 'akka saseru' (to worsen) instead.

English speakers might use 'grow' or 'expand' more casually. 'Develop' is the closest match, but 'hatten saseru' is slightly more formal than the average English use of 'develop' in casual talk.

Japanese government white papers (Keizai Hakusho). Corporate slogans (e.g., 'Developing the future'). Strategy games like 'Nobunaga's Ambition' use this for province development.

Preguntas frecuentes

10 preguntas

Generally, no. For children, use 'sodateru' (to raise) or 'seichou saseru' (to make grow). 'Hatten saseru' sounds too mechanical or academic for a person's biological growth, though you might use it for 'developing a child's potential' (kanousei o hatten saseru) in an educational context.

'Kaihatsu suru' is often for the initial creation or 'opening up' (like land development or software R&D). 'Hatten saseru' is for the ongoing evolution and expansion of that thing once it exists. You 'kaihatsu' an app, then 'hatten saseru' your app business.

Yes, it is a formal Kango (Sino-Japanese) word. In casual speech, people might use 'hirogeru' (to widen/spread) or 'motto yoku suru' (to make better). It is perfect for business, news, and essays.

Yes, it is a transitive verb. You must specify *what* you are developing using the particle 'o'. If there is no object, you should use the intransitive form 'hatten suru'.

No. Developing photos is 'genzou suru' (現像する). 'Hatten saseru' is only for growth and progress.

The particle 'ni' is used. For example, 'A o B ni hatten saseru' (Develop A into B).

While they share the same kanji for 'hatten', 'hattenba' (発展場) is a specific slang term for cruising spots in the LGBTQ+ community. In general conversation, 'hatten saseru' has no such connotation and is purely about growth/development.

Usually, the subject is a human, a group, or an abstract force like 'technology' or 'education.' A machine itself doesn't usually 'develop' things unless it's an AI 'developing' a solution.

It is 'jizoku kanou na hatten' (持続可能な発展). To say 'to develop sustainably,' you say 'jizoku kanou na katachi de hatten saseru'.

'Shinkou suru' (振興する) is specifically about promoting or boosting an industry or interest, often through government support. 'Hatten saseru' is the general act of making it grow.
