加速 30초 만에
- 加速 (Kasoku) means acceleration or speeding up, applicable to both physical movement and abstract processes like business or social trends.
- It is commonly used as a noun or a 'suru' verb (加速する) to describe things gaining momentum naturally or being forced to speed up.
- In professional contexts, it describes the rapid progression of technology, aging populations, or economic shifts, making it a B2-level essential.
- Key phrases include '加速がつく' (to gain momentum) and '急加速' (sudden acceleration), often appearing in news, science, and automotive discussions.
The Japanese word 加速 (kasoku) is a compound noun formed by two kanji: 加 (ka), meaning 'to add' or 'increase,' and 速 (soku), meaning 'speed' or 'velocity.' At its most fundamental level, 加速 refers to the physical act of increasing speed, such as a vehicle moving faster. However, in contemporary Japanese, its usage has expanded significantly beyond the physical realm into the abstract, describing the intensification or rapid progression of social trends, economic shifts, and technological advancements. When you use 加速, you are describing a state where the rate of change is not just steady, but is actively increasing over time. This makes it a vital word for discussing everything from physics and driving to business strategy and global warming.
- Physical Acceleration
- Refers to an object gaining velocity. For example, a car accelerating on a highway or a runner sprinting toward the finish line.
- Abstract Progression
- Used to describe processes that are happening faster than before, such as 'the acceleration of the aging society' (高齢化の加速).
- Transitive vs. Intransitive
- While 加速 is a noun, it often functions as a verb with 'suru' (加速する). It can be used both for things that speed up on their own and things that are forced to speed up by external factors.

— Electric vehicles can accelerate faster than gasoline cars.
パンデミックの影響で、リモートワークの導入が加速した。

— This new drug has the effect of accelerating cell regeneration.
景気回復の動きが加速している。
— The movement toward economic recovery is accelerating.
ロケットが宇宙空間でさらに加速を続けた。
— The rocket continued to accelerate further in outer space.
- Economic Context
- Used to describe inflation or market growth that is picking up pace.
- Social Context
- Used for trends like urbanization or digitalization that are moving faster than predicted.
Using 加速 (kasoku) correctly requires understanding its flexibility as both a noun and a Suru-verb. In daily conversation, you might hear it regarding driving, but in professional settings, it is a powerhouse word for describing momentum. When you want to say something is naturally gaining speed, use 加速する. If you are the one driving the change, 加速させる is more appropriate. It is also common to see it paired with particles like が (ga) to indicate what is accelerating, or を (o) when an action is being accelerated.
- With 'Ni' (に)
- Used to indicate the cause of acceleration. Example: 'AIの進化によって、開発がさらに加速した' (Development accelerated further due to the evolution of AI).
- With 'Gao' (がつく)
- The phrase '加速がつく' means to gain momentum or to start moving faster and faster. It's often used when a process has passed its initial slow phase.
- Compound Words
- You will often see '加速' combined with other words, such as '加速器' (particle accelerator) or '急加速' (sudden acceleration).
In a B2 level context, you should focus on using 加速 to describe complex systems. Instead of just saying 'things are getting faster,' use 加速 to describe the 'acceleration of digital transformation' (デジタルトランスフォーメーションの加速) or the 'acceleration of climate change' (気候変動の加速). This elevates your Japanese from simple descriptions to analytical observations. Remember that 加速 is almost always positive or neutral in a physical sense, but in social contexts, it can describe negative trends (like the acceleration of a disease's spread) just as easily as positive ones.
You will encounter 加速 in a variety of high-frequency environments. In the automotive industry, it is a standard term for performance metrics. Car reviews will constantly compare the 'acceleration' (加速性能) of different models. In news broadcasting, particularly business and technology segments, it is used to describe market trends. For instance, 'The shift toward renewable energy is accelerating' (再生可能エネルギーへの転換が加速している).
In academic and scientific papers, 加速 is used in physics (acceleration = change in velocity over time) and biology (accelerated growth). In political discourse, leaders might talk about 'accelerating the implementation of policies' to address urgent social issues. Even in sports commentary, you might hear it when a player suddenly increases their pace to break away from the competition. Because it sounds professional and precise, it is a favorite for journalists and analysts who want to convey a sense of dynamic change.
One of the most frequent errors learners make is confusing 加速 (kasoku) with 速い (hayai). While 'hayai' is an adjective describing speed, 'kasoku' is the process of increasing that speed. You cannot say 'この車は加速だ' to mean 'this car is fast'; you must say 'この車は加速が速い' (this car's acceleration is fast) or 'この車は加速がいい' (this car has good acceleration).
Another mistake is using 加速 when 促進 (sokushin) is more appropriate. 促進 specifically means 'promotion' or 'facilitation' of a process, often implying a deliberate effort to make something go smoothly. While 加速 can be a result of 促進, 加速 focuses on the *rate* of speed, whereas 促進 focuses on the *encouragement* of the activity. For example, you 'promote' (促進) health, but the 'spread' of a virus 'accelerates' (加速). Using 加速 for things that don't have a 'rate' or 'speed' (like a feeling of love) would also be unnatural; it is best reserved for physical movement or measurable processes.
Understanding the synonyms of 加速 helps in choosing the right word for the right context. 促進 (Sokushin) is perhaps the closest, but it implies 'promotion' or 'furtherance'—making something happen more effectively. 進展 (Shinten) refers to 'progress' or 'development,' focusing on the advancement of a situation rather than just the speed.
スピードアップ (Speed-up) is the katakana equivalent, often used in casual business settings or sports, but it lacks the formal weight of 加速. 拍車をかける (Hakusha o kakeru) is an idiomatic expression meaning 'to spur on' or 'to give impetus to,' which is a great figurative way to describe acceleration. Lastly, 急ピッチ (Kyu-pitchi) is used when work or construction is being done at a 'rapid pitch' or very fast pace. While all these words touch on the idea of speed, 加速 remains the most versatile for describing the mathematical or systematic increase in the rate of any process.

팁
Driving Context
When driving in Japan, remember that '急加速' (sudden acceleration) is often cited in safety manuals as a cause of accidents. Use it to describe erratic driving. It is a key term in traffic safety.
Market Trends
In business reports, use '加速' to describe trends that are picking up pace. For example, '市場の拡大が加速している' (Market expansion is accelerating). This shows you understand market dynamics.
Physics Terminology
In physics, '加速' is a specific term. If you are studying STEM in Japanese, you will need to know '加速度' (acceleration) as a mathematical value. It is essential for engineering.
Social Issues
When discussing the 'aging society' (高齢化社会), '加速' is the standard word to describe how the problem is worsening. It appears in almost every government white paper on the topic.
Transitive vs Intransitive
Remember: 'Aが加速する' (A accelerates) vs 'BがAを加速させる' (B accelerates A). Choosing the right one shows high-level grammar control. It is a common point in JLPT N2/N1.
Synonym Choice
If you want to sound more natural in sports, use 'スパートをかける' (to put on a spurt) instead of '加速する' for the final dash. '加速' sounds a bit robotic in that specific moment.
Essay Writing
In essays, use '加速的に' (acceleratingly) to describe exponential growth. It is a powerful adverb that adds weight to your arguments. It sounds very professional.

자주 묻는 질문
10 질문Yes, you can use it when a runner increases their speed. For example, '彼はゴール前で加速した' (He accelerated before the finish line). It sounds more technical than just saying 'faster.'
スピードアップ is more casual and common in daily conversation or sports. 加速 is more formal and used in news, science, or business reports. Both mean the same thing fundamentally.
Not necessarily. You can use it for negative trends, like '病気の拡散が加速する' (The spread of the disease is accelerating). It simply describes the rate of change.
The opposite of 加速 (Kasoku) is 減速 (Gensoku). It follows the same grammar rules (減速する, 減速させる).
It's rare. Usually, we use words like '高まる' (takamaru) for feelings. However, you might say '不安が加速する' (anxiety accelerates) to mean it's getting worse quickly.
It means 'to gain momentum.' It's used when a process starts moving faster and faster, like a ball rolling down a hill or a successful business.
It is a technical term for a 'particle accelerator' used in physics. Unless you are a scientist, you won't use it daily, but you'll see it in science news.
No, 'early' is '早い' (hayai). 加速 only refers to the increase in speed, not the time of day or being ahead of schedule.
It means 'sudden acceleration.' It's often used in driving contexts to describe stepping hard on the gas pedal, which is usually discouraged for safety.
You can use it to talk about project timelines: 'プロジェクトの進捗を加速させるため、リソースを追加します' (We will add resources to accelerate the project's progress).
