拡散 en 30 segundos
- 拡散 (kakusan) means spreading out, like gases, information, or ideas.
- Used for physical things (gases) and abstract things (news, trends).
- Common in science, news, and social media discussions.
- Distinguish from 拡大 (expansion) and 普及 (widespread use).
The Japanese word 拡散 (かくさん - kakusan) literally means 'to spread out' or 'to diffuse'. It's a versatile term used in various contexts, from the physical spreading of particles to the dissemination of information and ideas. You'll encounter it when talking about how things expand, disperse, or become widely known.
- Physical Spreading
- This refers to the natural tendency of substances, like gases or liquids, to spread out and occupy a larger space. Think of the smell of perfume spreading in a room, or smoke dispersing into the air. In science, this is a fundamental concept.
- Information and Ideas
- This is a very common usage in modern times. It describes how news, rumors, opinions, or even cultural trends spread rapidly, especially through social media and the internet. When something goes 'viral', it's a form of 拡散.
- Cultural and Social Influence
- It can also describe the way certain customs, fashions, or ideologies spread from one group or region to another, becoming more widespread over time. This can be a gradual process or a rapid adoption.
- Light and Radiation
- In physics, 拡散 can refer to the spreading of light or radiation from a source.

Understanding how to construct sentences with 拡散 is key to using it effectively. It's most commonly used as a noun, often modified by particles or followed by verbs that describe its action or effect.
- Noun Usage
- As a noun, 拡散 is often the subject or object of a sentence. It can be followed by particles like が (ga) to indicate the subject performing the action, or を (o) to indicate what is being spread. It can also be used with verbs like する (suru - to do) to form compound verbs, meaning 'to spread' or 'to diffuse'.
- With Verbs of Action
- Verbs like 進む (susumu - to advance, proceed), 始まる (hajimaru - to begin), 拡大する (kakudai suru - to expand), and 抑制する (yokusei suru - to suppress) are often used in conjunction with 拡散 to describe its progression or control.
- Describing Speed and Extent
- Adverbs and adjectives can be used to specify the manner or degree of spreading, such as 速やかに (sumiyaka ni - quickly), 広範囲に (kouhan'i ni - widely), or 容易に (yōi ni - easily).

新しい技術は世界中に拡散していった。
デマの拡散を防ぐための対策が取られた。
You'll encounter 拡散 in a variety of everyday and specialized situations. Its meaning is broad, so its usage reflects that diversity.
- News and Current Events
- News reports frequently use 拡散 when discussing the spread of diseases, the dissemination of important information, or the rapid spread of social trends and online content. You might hear about efforts to control the 拡散 of a virus or the 拡散 of public opinion on a certain issue.
- Science and Technology
- In scientific contexts, 拡散 is used to describe diffusion processes in chemistry and physics, such as the 拡散 of gases, heat, or particles. In technology, it can refer to the spread of signals or data.
- Social Media and Internet
- This is where 拡散 is extremely prevalent. Discussions about viral content, misinformation, online communities, and the reach of a particular post or hashtag will often use this word. It's crucial for understanding online communication dynamics.
- Business and Marketing
- Marketers might talk about the 拡散 of their brand's message or product awareness. It can also refer to the spread of business strategies or industry trends.
- Everyday Conversations
- In casual settings, people might use it to describe how gossip spreads, how a new trend becomes popular, or even how a strong smell fills a space.

While 拡散 is a useful word, learners might sometimes misuse it or confuse it with similar concepts. Being aware of these potential pitfalls can help you use it more accurately.
- Confusing with 'Expansion' (拡大 - kakudai)
- While both can involve spreading, 拡大 (kakudai) often implies growth in size or scope, like a company expanding its operations or a city growing. 拡散 is more about dispersal and distribution. For example, a disease might spread (拡散) and then its impact might expand (拡大).
- Overusing for 'Distribution' (配布 - haifu)
- 配布 (haifu) specifically means 'to distribute' or 'to hand out' things, usually in a planned and organized manner, like distributing flyers or samples. 拡散 is a more general spreading, often less controlled.
- Using it for 'Spread' of a Solid Object
- While 拡散 can apply to physical substances, it's most common for gases, liquids, or abstract things like information. For solid objects, you'd typically use verbs like 散らばる (chirabaru - to scatter) or 落ちる (ochiru - to fall).
- Neglecting the 'Source' or 'Direction' of Spread
- The context usually implies a source from which something is spreading. If you're talking about something being spread *to* a specific place, you might use other sentence structures or prepositions rather than just 拡散 alone.
これは拡散ではなく、拡大です。
チラシの拡散ではなく、配布が適切だ。
While 拡散 is a common and useful term, there are other Japanese words that express similar concepts of spreading, each with its own nuance and specific application.
- 拡大 (かくだい - kakudai)
- Meaning: Expansion, enlargement, growth.
Difference: 拡大 focuses more on an increase in size, scope, or scale. It's about becoming bigger. 拡散 is about dispersal and distribution. You might see 拡大 used for business growth, city expansion, or the increase in the area affected by something. For example, a fire might spread (拡散) and then its burned area might expand (拡大). - 普及 (ふきゅう - fukyuu)
- Meaning: Popularization, widespread use, prevalence.
Difference: 普及 implies that something has become common or widely adopted by many people. It's often used for technology, ideas, or practices that have become mainstream. While 拡散 describes the *process* of spreading, 普及 describes the *state* of being widespread and accepted. For example, smartphones have spread (拡散) and have become widely used (普及). - 浸透 (しんとう - shintou)
- Meaning: Penetration, permeation, diffusion.
Difference: 浸透 suggests a deeper, more thorough spreading, often into something else. It can be used for liquids soaking into a material, or for ideas and cultures gradually becoming ingrained. It implies a more subtle and pervasive spread than the more general 拡散. - 流布 (るふ - rufu)
- Meaning: Circulation, dissemination (often of information, rumors, or beliefs).
Difference: 流布 is very similar to 拡散 when talking about information. It specifically refers to the spreading of something, especially something that is being circulated widely. It can sometimes carry a nuance of being spread by word of mouth or through widespread publication.
新しい文化は徐々に拡散し、やがて普及した。
デマの拡散と、その流布は似ているが、後者は情報伝達のニュアンスが強い。

Nivel de dificultad
The word itself is moderately difficult due to its abstract nature and the kanji. However, its usage in context, especially in news and scientific articles, can increase the overall difficulty of reading comprehension.
Accurately using 拡散 requires understanding its nuances and distinguishing it from similar words. Learners might struggle with choosing the correct context and grammatical patterns.
Pronunciation is manageable, but using it naturally in conversation requires practice and an understanding of its common contexts. It's more likely to appear in formal or semi-formal discussions.
Recognizing 拡散 when spoken depends on the clarity of pronunciation and the context. It's a common enough word in media that listeners familiar with B2 level Japanese should be able to identify it.

Using 拡散 for physical objects scattering.
→
Use 散らばる (chirabaru) for objects scattering, e.g., ゴミが散らばる (trash scatters).
拡散 is typically for gases, liquids, information, or abstract concepts. For solid objects being dispersed, 散らばる is more appropriate and natural.
-
Confusing 拡散 (spreading) with 拡大 (expansion).
→
Use 拡大 for growth in size or scope, e.g., 事業を拡大する (expand business). Use 拡散 for dispersal, e.g., 噂が拡散する (rumor spreads).
拡大 refers to becoming larger in scale or area, while 拡散 refers to dispersing from a point. They are related but distinct concepts.
-
Using 拡散 when 普及 (widespread use) is more appropriate.
→
Use 普及 to describe something that has become common or widely adopted, e.g., スマートフォンの普及 (widespread use of smartphones).
拡散 describes the process of spreading, while 普及 describes the state of being widespread and accepted. 拡散 leads to 普及.
-
Pronouncing 拡散 with equal stress on each syllable.
→
Pronounce with a slight emphasis on the first syllable 'ka' and a clear nasal 'n' at the end.
Japanese pronunciation for compound words like this is often flatter than in English, with the final nasal sound being key. Over-stressing each syllable can sound unnatural.

Origen de la palabra
The word 拡散 is a Sino-Japanese compound word, meaning it is composed of characters borrowed from Chinese. The kanji characters themselves have specific meanings that contribute to the overall sense of the word.
Significado original: The character 拡 (kaku) means 'to enlarge,' 'to expand,' or 'to widen.' The character 散 (san) means 'to scatter,' 'to disperse,' or 'to spread.' Together, they convey the idea of scattering and expanding outwards.
Sino-Xenic (Kanji-based words originating from Chinese)Contexto cultural
When discussing the spread of negative things like diseases or rumors, it's important to be mindful of the potential for panic or stigma. The term 拡散 itself is neutral, but the context and what is being spread can carry sensitive implications.
In English, we use words like 'spread,' 'diffusion,' 'dissemination,' and 'propagation.' The nuance of 拡散 often aligns with 'diffusion' in scientific contexts and 'dissemination' or 'spread' for information and ideas.

10 preguntas広がる (hirogaru) is a more general and common verb meaning 'to spread out' or 'to widen,' often used for physical things like stains, smiles, or areas. 拡散 (kakusan) is a more formal noun (or verb with する) that implies a more deliberate or scientific process of dispersal, especially for gases, information, or abstract concepts. For example, a smell might 広がる, but a disease's spread is more often described as 拡散.
拡散 is very commonly used when talking about the spread of information, especially on social media and the internet. It describes how news, rumors, opinions, or trends move from one person or group to many others. Phrases like '情報拡散' (information diffusion) and 'SNSでの拡散' (spread on social media) are frequent.
The term 拡散 itself is generally neutral, describing the process of spreading. However, the context determines whether the spread is perceived as positive or negative. For example, the 拡散 of a disease is negative, while the 拡散 of important public health information is positive. The 拡散 of rumors can be negative.
While 拡散 primarily applies to gases, liquids, information, and abstract concepts, it can sometimes be used for physical substances if they are dispersing. However, for solid objects scattering, verbs like 散らばる (chirabaru - to scatter) are more common. For example, you wouldn't typically say 'stones 拡散' but rather 'stones scattered' (石が散らばった).
Common antonyms include 集中 (shuuchuu - concentration), 収束 (shuusoku - convergence/resolution), 限定 (gentei - limitation), and 封じ込め (fuujikome - containment). These words describe the opposite of spreading out, such as gathering in one place, coming to an end, or being restricted.
When something 'goes viral' on social media, it means it is spreading extremely rapidly and widely. This rapid and extensive spread is a prime example of 拡散. So, 'viral spread' can be accurately described as 情報の急速な拡散 (jouhou no kyuusoku na kakusan - rapid diffusion of information).
Yes, 拡散 is very frequently used in scientific contexts, particularly in physics and chemistry, to describe diffusion processes. This includes the diffusion of gases, heat, particles, or even light. For example, '気体の拡散' (diffusion of gases) or '光の拡散' (diffusion of light) are common scientific terms.
伝播 (denpa) is often more technical and used for the transmission of specific things like waves, signals, or infectious agents, focusing on passing from one point to another. 拡散 is a broader term for spreading out into a larger space or audience. For instance, a virus might 伝播 from person to person, but its overall presence in a population could be described as 拡散.
A mnemonic could be to imagine a 'cat' (kaku) 'singing' (san) very loudly. The sound spreads everywhere, which is the meaning of 拡散. Another visual is ink spreading in water.
For very informal situations, especially with physical spreading, 広がる (hirogaru) is more common and natural than 拡散. For example, 'The stain spread' would be more naturally 'シミが広がった' than 'シミが拡散した'.
