설명 送信 in your Level:
At the A1 level, you don't need to worry too much about the technical details of '送信' (sōshin). Just remember that it is the word you see on the 'Send' button of your favorite apps. In Japanese, 'sōshin' means sending a message or an email. You might see it on a screen when you use a computer or a smartphone. It is a very useful word because it helps you understand how to use Japanese websites and applications. When you see a button with these characters, it means 'click here to send your message'. You don't need to use it in complex sentences yet. Just knowing that 'sōshin' = 'Send (digital)' is a great start! You might also see 'sōshin-zumi', which means your message has been successfully sent. Try to find this word on your phone's language settings if you change them to Japanese.

At the A2 level, you can start using '送信' (sōshin) as a verb. You do this by adding 'suru' at the end: 'sōshin suru'. This is specifically used for things like emails (mēru) and messages. For example, you can say 'Mēru o sōshin shimashita' (I sent the email). It is important to know the difference between 'okuru' and 'sōshin'. 'Okuru' is a general word for sending anything, like a gift or a letter. 'Sōshin' is specifically for digital things. So, if you are talking about your computer or phone, 'sōshin' is a very natural word to use. You should also learn the word 'jushin', which means receiving a message. These two words often go together in digital settings. If you see 'sōshin-errā' (transmission error), you know that something went wrong with your internet or the app.

At the B1 level, you should be comfortable using '送信' (sōshin) in professional and formal settings. This word is the standard term for business correspondence. You should also learn compound words like 'sōshin-moto' (sender) and 'sōshin-saki' (recipient). In a business email, you might write 'Shiryo o sōshin itashimashita' (I have sent the materials) to sound more professional. You should also be aware of 'go-sōshin', which refers to sending an email to the wrong person—a common mistake in the corporate world. Understanding the nuance between 'sōshin' (sending data) and 'hasshin' (broadcasting or starting a call) becomes important at this stage. You will also encounter 'sōshin' in more technical contexts, such as describing how data moves between a server and a client in an IT environment.
At the B2 level, your understanding of '送信' (sōshin) should include its use in technical, scientific, and legal contexts. You should understand how it describes the transmission of radio waves, satellite data, and encrypted information. You might encounter phrases like 'shingō o sōshin suru' (to transmit a signal) in academic texts or news reports about technology. You should also be able to use the word in the context of data privacy and security, such as 'kojin jōhō no sōshin' (the transmission of personal information). At this level, you should also be proficient in using honorifics with 'sōshin' in high-stakes business environments, such as 'go-sōshin itadaki, arigatō gozaimasu' (thank you for sending [the document]). You should also be able to distinguish 'sōshin' from more specific terms like 'tensō' (forwarding) or 'haishin' (distribution/streaming).

At the C1 level, you are expected to understand the fine nuances of '送信' (sōshin) in complex discussions about telecommunications policy, network engineering, and digital ethics. You might analyze the 'sōshin-sha' (sender) responsibilities in terms of anti-spam laws or data protection regulations. You should be able to discuss the 'sōshin doryoku' (transmission power) of radio stations or the 'sōshin kōryū' (transmission efficiency) of a network. In literature or high-level journalism, 'sōshin' might be used metaphorically to describe the dispatch of ideas or cultural signals across borders. Your mastery of the word should allow you to use it flawlessly in technical presentations, legal documents, and formal debates about the digital age. You should also be familiar with archaic or highly specialized variations of the term used in specific industries like maritime signaling or telegraphy history.

At the C2 level, '送信' (sōshin) is a word you use with total native-like precision. You understand its historical evolution from the era of telegraphy to modern fiber-optic and quantum communication. You can engage in deep technical discussions about 'sōshin gijutsu' (transmission technology) and its impact on global society. You are capable of identifying subtle misuses of the word in translated texts and can suggest the perfect alternative (e.g., 'haishin', 'denpō', or 'hassō') based on the exact context and desired tone. Your command over the word includes an awareness of its role in complex kanji compounds used in government white papers and advanced scientific research. You can also appreciate and use the word in creative writing to evoke the sterile, efficient, or distant nature of digital communication, contrasting it with the warmth of physical presence.

送信 30초 만에

  • Refers specifically to digital or signal transmission.
  • Commonly seen as a button label on Japanese apps.
  • Functions as both a noun and a suru-verb (送信する).
  • Opposite of 'jushin' (receiving) and different from 'okuru' (physical).

The Japanese word 送信 (そうしん - sōshin) is a fundamental noun and suru-verb that every intermediate learner must master. At its core, it refers to the act of sending information, signals, or messages from one point to another. While the English word 'send' is broad enough to cover physical packages and digital emails, sōshin is specifically reserved for the digital and telecommunication realms. You wouldn't use it to send a box of chocolates to your grandmother, but you would use it every time you hit the 'Send' button on your smartphone or computer.

Etymology Breakdown
The first kanji, 送 (sō), means to send or escort. It is the same character found in the verb okuru. The second kanji, 信 (shin), represents trust, belief, or more technically in this context, a signal or message (as seen in shingō for traffic lights). Together, they literally mean 'sending a message/signal'.

In a modern Japanese context, this word is ubiquitous. If you look at any Japanese interface for Gmail, Outlook, or LINE, the button you click to dispatch your message is labeled 送信. It carries a professional and technical nuance, making it the standard choice for business communications and technical documentation regarding data transmission.

メールを書き終えたら、右上の送信ボタンを押してください。 (Once you finish writing the email, please press the send button in the top right.)

Furthermore, the word extends beyond just text. It is used in physics and engineering to describe the transmission of radio waves, satellite signals, and internet packets. When a server sends data to a client, the process is described as sōshin. This makes it an essential term for anyone working in IT, media, or logistics in Japan. The opposite of this word is 受信 (jushin), which means 'receiving'. Together, they form the concept of sōjushin (transmission and reception).

Formal Context
In business Japanese, you might use the honorific form go-sōshin when referring to a client sending you a document, or apologize for a go-sōshin (misdirected email) if you accidentally sent something to the wrong person.

Understanding the nuance of sōshin helps you navigate the Japanese digital landscape with confidence. It is a word that bridges the gap between everyday communication and highly technical data exchange, serving as a pillar of modern Japanese vocabulary.

Using 送信 (sōshin) correctly involves understanding its role as a 'suru-verb' (noun that becomes a verb by adding suru). In most cases, the object being sent is marked with the particle を (o), and the destination is marked with に (ni).

昨日、部長に報告書を送信しました。 (I sent the report to the department manager yesterday.)

Common Grammatical Patterns
1. [Object] を送信する (To send [Object])
2. [Destination] に送信する (To send to [Destination])
3. 送信が完了する (Sending is completed)
4. 送信に失敗する (Sending failed)

When you are talking about the state of a message, you often use the past tense or the te-iru form. For example, sōshin-zumi means 'already sent'. This is a common label in email folders. If an email is currently being sent, you might see sōshin-chū (now sending).

In more complex sentences, sōshin can be combined with other nouns to create compound terms. For instance, sōshin-moto refers to the sender (the source of the transmission), and sōshin-saki refers to the recipient (the destination). These are essential terms for filling out forms or setting up software configurations.

送信エラーが発生したため、再送してください。 (A transmission error occurred, so please resend it.)

Lastly, consider the polite form. When asking someone to send you something in a business context, you would say gosōshin kudasai or gosōshin itadakemasu ka. This adds a layer of professionalism that the simple verb okutte kudasai lacks. Mastering these variations allows you to communicate effectively across different social tiers in Japan.

You will encounter 送信 (sōshin) in almost every facet of modern Japanese life, particularly where technology is involved. The most immediate place is on your smartphone. Whether you are using LINE, Twitter (X), or Instagram, the action of posting or messaging involves sōshin.

In the Office
In a Japanese office, you will hear colleagues saying, 'Mēru sōshin shimashita' (I've sent the email). During meetings, someone might ask, 'Shiryo no sōshin wa owarimashita ka?' (Is the sending of the materials finished?). It is the standard professional jargon for all digital correspondence.

Beyond the office, you will hear it in automated voice systems. If you are using a fax machine (still common in some parts of Japan) or a specialized piece of medical or industrial equipment, the voice prompt might say, 'Dēta o sōshin-chū desu' (Data is being transmitted). This reinforces the word's association with mechanical or electronic processes.

ファックスの送信が終わるまで、電話を切らないでください。 (Please do not hang up until the fax transmission is finished.)

In media and news, sōshin is used when discussing satellite launches or deep-space communication. A news anchor might report that a probe has 'sent signals back to Earth' using the term shingō o sōshin shita. This highlights the word's capability to describe transmission over vast distances, not just between two people in an office.

Finally, you will see it in error messages. If your Wi-Fi is down or a server is unresponsive, you will see 'Sōshin ni shippai shimashita' (Failed to send) on your screen. Knowing this word helps reduce the anxiety of seeing Japanese error messages, as you immediately understand the nature of the problem.

The most frequent mistake learners make with 送信 (sōshin) is over-extending its meaning to physical objects. Because the English word 'send' is so versatile, it's easy to assume sōshin is its direct equivalent. However, as noted before, sōshin is purely for data and messages.

Mistake #1: Sending Physical Goods
Incorrect: 荷物を送信しました。 (Nimotsu o sōshin shimashita).
Correct: 荷物を送りました。 (Nimotsu o okurimashita).
Explanation: Use 'okuru' or 'hassō' for physical items.

Another common error is confusing sōshin with hasshin. While both involve 'sending', 発信 (hasshin) usually refers to the act of initiating a call, broadcasting a signal, or 'putting information out there' (like a blog post or a press release). Sōshin is more about the specific act of moving a file or message from A to B.

間違いやすい例：情報を送信する vs 情報を発信する。 (Sending data vs. Disseminating information.)

Learners also sometimes struggle with the 'suru' aspect. You cannot simply say 'Mēru sōshin' in a full sentence; you must include the verb 'suru' or its polite variations. However, on buttons or in list titles, '送信' alone is perfectly acceptable as a noun label.

Finally, don't confuse sōshin with tensō (forwarding). If you receive an email and want to send it to someone else, that is tensō. Using sōshin in that context might imply you are the original author of the message, which could lead to confusion in a business setting.

To truly master 送信 (sōshin), you must know how it compares to its synonyms and related terms. Each word carries a specific nuance that dictates when it should be used over sōshin.

Comparison: Sōshin vs. Okuru
Okuru (送る): The general, all-purpose verb for 'to send'. It is used for emails, letters, people, and packages. It is less formal than 'sōshin'.
Sōshin (送信): Technical and formal. Used specifically for digital data and messages.
Comparison: Sōshin vs. Hasshin
Hasshin (発信): Focuses on the 'origin' or the 'act of starting' a transmission. Used for making phone calls or broadcasting information to a wide audience.

Another important word is 配送 (haisō). This is the word you use for delivery services. When Amazon sends you a package, they are performing haisō. Even though it contains the 'sō' (send) kanji, it is entirely physical.

電子メールは送信、荷物は配送。 (Emails are 'sōshin', packages are 'haisō'.)

Lastly, consider 返信 (henshin), which means 'reply'. If you are sending a message back to someone, henshin is much more descriptive and appropriate than just using sōshin. By choosing the most specific word, you demonstrate a higher level of Japanese proficiency.

How Formal Is It?

재미있는 사실

The kanji '信' in '送信' also appears in 'shinjiru' (to believe). This is because a message or signal is something you 'trust' to be true and delivered.
