速度 30 सेकंड में
- Means 'speed' or 'velocity' in Japanese.
- Used for physical movement (cars, wind).
- Used for digital connections (internet, Wi-Fi).
- Used for the pace of abstract processes (growth).
The Japanese word 速度 (sokudo) is a formal and highly common noun used to describe the rate at which someone or something moves, operates, or progresses. It translates directly to 'speed,' 'velocity,' or 'pace.' Understanding this word is essential for navigating daily life in Japan, from reading road signs to discussing internet connections and analyzing business progress. Unlike the more casual word スピード (supiido) or the native Japanese word 速さ (hayasa), 速度 carries a slightly more technical, objective, or formal nuance, making it the preferred choice in written instructions, news reports, and official documents.
- Physical Speed
- Refers to the literal movement of objects, such as cars, trains, or wind.
車の速度を落としてください。(Please reduce the speed of the car.)
Beyond physical movement, 速度 is extensively used in the digital realm. In modern Japanese, one of the most frequent contexts for this word is discussing internet or data transfer rates. Whether you are setting up a new Wi-Fi router or complaining about a lagging video, you will use this term.
- Digital & Connection Rate
- Describes how fast data is transmitted or processed.
インターネットの通信速度が遅いです。(The internet connection speed is slow.)
Furthermore, 速度 can describe the pace of abstract concepts, such as economic growth, learning, or the progression of a disease. This makes it a versatile vocabulary word that scales from beginner daily conversations to advanced academic discourse.
- Process Pace
- The rate at which a process, project, or abstract phenomenon advances.
プロジェクトの進行速度を上げる必要があります。(We need to increase the speed of the project's progress.)
経済の回復速度が予想より早いです。(The speed of economic recovery is faster than expected.)
タイピングの速度を測るテストを受けました。(I took a test to measure my typing speed.)
Using 速度 correctly depends on pairing it with the right verbs and adjectives. Because it is a quantitative noun, it is typically described as being 'fast' (速い - hayai) or 'slow' (遅い - osoi), rather than 'high' or 'low' in everyday conversation, although 'high speed' (高速 - kousoku) is used as a compound noun. Let us explore the most common grammatical patterns and contexts where you will need to use this word.
- Describing Speed
- Use adjectives like 速い (fast) and 遅い (slow).
このパソコンは処理速度が非常に速い。(This computer has a very fast processing speed.)
When you want to talk about changing the speed, you will use verbs like 上げる (ageru - to raise/increase) or 落とす (otosu - to drop/decrease). You can also use 出す (dasu - to put out) to mean 'to gain speed' or 'to go fast.'
- Changing Speed
- Verbs used to manipulate the rate of movement or progress.
カーブでは速度を落としてください。(Please reduce your speed at the curve.)
もっと速度を上げましょう。(Let's increase the speed.)
In compound nouns, 速度 acts as a suffix or prefix to create specific terms. For example, adding 計 (kei - meter) creates 速度計 (sokudokei - speedometer). Adding 制限 (seigen - limit) creates 速度制限 (sokudo seigen - speed limit). Understanding these compounds expands your vocabulary exponentially.
- Compound Nouns
- Combining 速度 with other kanji to specify the type of speed.
光の速度は秒速約30万キロメートルです。(The speed of light is about 300,000 kilometers per second.)
ダウンロード速度をテストする。(Test the download speed.)
The word 速度 is ubiquitous in Japanese society. You will encounter it in a wide variety of contexts, ranging from casual daily interactions to highly technical professional environments. Because Japan has a highly developed transportation infrastructure and is a technologically advanced nation, discussions about speed—whether of bullet trains or broadband networks—are incredibly common.
- Transportation and Driving
- Road signs, GPS navigation, and train announcements.
法定速度を守って運転してください。(Please drive observing the legal speed limit.)
Another major area where you will hear and see this word is in technology and telecommunications. When buying a smartphone, signing up for home internet, or reading tech reviews, the 'communication speed' is a primary selling point.
- Technology and Internet
- Discussions about Wi-Fi, 5G, processors, and data transfer.
このプランは通信速度が安定しています。(This plan has a stable connection speed.)
動画の再生速度を1.5倍にする。(Change the video playback speed to 1.5x.)
In news broadcasts and weather reports, 速度 is used to describe the movement of natural phenomena, such as typhoons, which frequently affect Japan. You will hear meteorologists discussing the speed at which a storm is approaching the archipelago.
- Weather and News
- Typhoon movement, wind speed, and earthquake waves.
台風は自転車並みの速度で進んでいます。(The typhoon is moving at the speed of a bicycle.)
風の速度が急に増した。(The wind speed suddenly increased.)
While 速度 is a straightforward noun, learners often make mistakes regarding its collocations (the words it naturally pairs with) and its nuances compared to similar words. A very common error is translating English adjectives literally when describing speed in Japanese.
- Mistake 1: Using 高い (High) and 低い (Low)
- In English, we say 'high speed' or 'low speed.' In Japanese conversation, using 高い/低い with 速度 sounds unnatural.
❌ 速度が高いです。(Incorrect)
✅ 速度が速いです。(Correct - The speed is fast.)
Another frequent mistake is confusing 速度 with 速さ (hayasa). While both translate to 'speed,' 速さ is the native Japanese word (wago) and feels more subjective, casual, and focused on the quality of being fast. 速度 is a Sino-Japanese word (kango) and feels objective, measurable, and formal.
- Mistake 2: Confusing 速度 and 速さ
- Using the formal 速度 in a very casual, emotional context.
❌ 彼の走る速度にびっくりした！(A bit too formal for casual speech)
✅ 彼の走る速さにびっくりした！(Correct - I was surprised by his running speed!)
✅ インターネットの速度を測定する。(Correct - Measure the internet speed. Objective/Technical.)
Lastly, learners sometimes misuse the verbs associated with changing speed. Instead of saying 'make the speed big,' you must use specific verbs.
- Mistake 3: Wrong Verbs for Speed Control
- Using 大きくする (make big) instead of 上げる (raise) or 出す (put out).
❌ 速度を大きくして。(Incorrect)
✅ 速度を上げて。(Correct - Increase the speed.)
✅ もっと速度を出して。(Correct - Go faster / Put out more speed.)
The Japanese language offers several words to express the concept of speed, pace, and rapidity. Choosing the right synonym depends on the context, the level of formality, and whether you are focusing on the objective measurement or the subjective feeling of speed. Let us compare 速度 with its most common alternatives.
- スピード (Supiido)
- The English loanword for speed. It is highly versatile and used in both casual and business contexts.
仕事のスピードが速い。(The speed of work is fast.)
As mentioned in the Common Mistakes section, 速さ (hayasa) is the direct native Japanese equivalent. It is formed by turning the adjective 速い (fast) into a noun by adding the suffix さ (-sa), which indicates a degree or state.
- 速さ (Hayasa)
- Focuses on the quality or degree of being fast. It is more subjective and conversational.
新幹線の速さに感動した。(I was moved by the speed of the bullet train.)
時の流れる速さを感じる。(I feel the speed at which time flows.)
When discussing the rhythm or rate of a continuous activity, such as walking, running a marathon, or completing a long-term project, the words ペース (peesu - pace) or テンポ (tenpo - tempo) are often more appropriate than 速度.
- ペース (Peesu) & テンポ (Tenpo)
- Used for the rhythm, rate, or step-by-step progression of an ongoing activity.
自分のペースで勉強する。(Study at your own pace.)
会話のテンポが良い。(The tempo of the conversation is good.)

सुझाव
Adjective Pairing
Always use 速い (fast) or 遅い (slow) with 速度. Never use 高い (high) or 低い (low). This is the #1 mistake learners make.
Driving Vocab
Memorize 速度制限 (speed limit) and 速度違反 (speeding violation). They are essential if you plan to drive in Japan.
Internet Speed
When buying a SIM card or Wi-Fi in Japan, look for 通信速度 (tsuushin sokudo). It tells you how fast your data will be.
Casual vs Formal
In a casual chat with friends, use スピード or 速さ. In a business meeting or written email, switch to 速度 for a professional tone.
Train Announcements
Listen carefully on the Shinkansen. You might hear announcements about reaching a certain 速度 (speed) or slowing down due to weather.
Compound Words
速度 loves to attach to other words. 処理速度 (processing speed), 再生速度 (playback speed), and 進行速度 (progress speed) are everywhere online.
Kanji Practice
Pay attention to the 辶 (shinnyou) radical in 速. It is drawn last! First draw the inner part (束), then the sweeping road radical.
Objective Measurement
Use 速度 when you can measure the speed with a number (km/h, Mbps). If it's just a feeling ('He eats fast'), use 速さ or 早く.
Accelerating Rate
Learn the phrase 加速度的に (kasokudoteki ni). It means 'at an accelerating rate' and makes you sound very advanced in business Japanese.
Typhoon Speeds
Japanese weather news often compares typhoon 速度 to human speeds, like '自転車並みの速度' (speed of a bicycle) to help people understand the danger.

अक्सर पूछे जाने वाले सवाल
10 सवालNo, this is a very common mistake. In Japanese, speed is described as 'fast' (速い) or 'slow' (遅い). You should say '速度が速い'. While '高速' (high speed) exists as a noun, the adjective pairing is strictly fast/slow.
'速度' is a formal, Sino-Japanese word used for objective measurements, machines, and data. 'スピード' is an English loanword used in both casual and business contexts, often for human actions or sports. In a formal report, use '速度'.
The word is '速度制限' (sokudo seigen). You will see this on road signs everywhere in Japan. Another related term is '法定速度' (houtei sokudo), which means the legal speed limit.
Yes, absolutely. '通信速度' (tsuushin sokudo - communication speed) or '回線速度' (kaisen sokudo - line speed) are the standard terms used by internet providers and tech reviewers in Japan.
You can say 'もう少し速度を落としてください' (Mou sukoshi sokudo o otoshite kudasai). A slightly more casual but polite way is 'もう少しゆっくり走ってください' (Please drive a little slower).
To increase speed, use '速度を上げる' (sokudo o ageru) or '速度を出す' (sokudo o dasu). To decrease speed, use '速度を落とす' (sokudo o otosu).
Yes. You can say '成長速度' (seichou sokudo - speed of growth) or '進行速度' (shinkou sokudo - speed of progress). It is very common in business and academic contexts.
It is Atamadaka (頭高型). The pitch starts high on the first mora 'ソ' (so) and drops for 'クド' (kudo). Pronounce it SO-ku-do.
'加速度' (kasokudo) means 'acceleration'. It is a physics term but is also used metaphorically, like '加速度的に増える' (to increase at an accelerating rate).
Yes. The kanji 速 has the 'movement/road' radical (辶), which relates to traveling. 度 has the 'hand' and 'house' elements, used for measuring degrees. Together, measuring movement = speed.
