承諾する

The Japanese verb 承諾する (shoudaku suru) is a formal and sophisticated way to express the act of consenting, agreeing to, or approving a request, proposal, or contract. Unlike the more common 賛成する (sansei suru), which simply means to agree with an opinion or idea, 承諾する carries a weight of legal or official commitment. It is most frequently encountered in business settings, legal documents, and formal social interactions where one party formally accepts a condition or offer put forward by another.

Etymology and Kanji

The first kanji, 承 (shou), means 'to receive' or 'to inherit,' suggesting a humble reception of information or a request. The second kanji, 諾 (daku), means 'to consent' or 'to say yes.' Together, they form the concept of receiving a request and giving one's affirmative consent to it.

In a professional context, if a client asks you to extend a deadline and you agree to it officially, you are performing an act of 承諾. It implies that you have considered the request and have formally decided to grant it. This word is rarely used in casual conversation with friends; saying '承諾する' to a friend who asks to borrow a pen would sound incredibly stiff and jokingly robotic.

Furthermore, 承諾 is often paired with terms like 承諾書 (shoudakusho), which is a written letter of consent. This highlights the word's association with documentation and official record-keeping. Whether it is a marriage proposal in a traditional setting or a high-stakes corporate merger, 承諾 is the bridge between a proposal and its execution. It signifies that the 'receiver' (承) has given their 'word' (諾).

Social Nuance

In Japanese society, the act of 承諾 often comes after a period of 'nemawashi' (laying the groundwork). By the time the formal 承諾 is given, all parties usually already know the outcome. The word represents the official culmination of negotiations.

When using this word, remember that it is a transitive verb that takes the particle を (wo) for the object being consented to, or it can be used in the form 承諾を得る (shoudaku wo eru), meaning 'to obtain consent.' Using it correctly demonstrates a high level of Japanese proficiency and an understanding of formal interpersonal dynamics.

Using 承諾する requires an understanding of grammatical structures that typically accompany formal verbs. Because it is a 'suru' verb, it can be easily conjugated into various forms such as 承諾します (polite), 承諾した (past), or 承諾しない (negative). However, its usage is often dictated by the relationship between the requester and the consenter.

Grammatical Pattern 1: [Request/Proposal] + を + 承諾する

This is the most direct way to use the verb. You specify what is being agreed to. Example: 申し出を承諾する (Accept an offer).

In a professional environment, you might hear this in the context of project management or sales. If a vendor agrees to a specific price point, the manager might report, '業者が価格を承諾しました' (The vendor has consented to the price). This indicates a firm agreement has been reached.

Grammatical Pattern 2: [Person] + に + [Request] + を + 承諾してもらう

This pattern uses the causative-benefactive structure to show that you received the favor of someone's consent. This is very common when talking about authority figures or clients.

When you are the one seeking permission, the focus shifts to the act of receiving the consent. For example, '上司に私の異動を承諾してもらった' (I had my transfer consented to by my boss). This emphasizes that the boss granted the request, which was a beneficial action for the speaker.

It is also important to note the negative form 承諾しかねる (shoudaku shikaneru). This is a very polite way of saying 'I cannot consent' or 'I am unable to agree.' In Japanese business culture, direct refusal (承諾しません) is often avoided in favor of these softer, more nuanced expressions that imply difficulty rather than a flat 'no.'

Finally, when using it in a passive sense, 承諾される (shoudaku sareru), it refers to a proposal being accepted by someone else. '私の提案がようやく承諾された' (My proposal was finally consented to). This structure is useful for reporting outcomes where the focus is on the proposal itself rather than the person who agreed to it.

If you are working in Japan or dealing with Japanese companies, you will hear 承諾する constantly. It is the language of the office, the courtroom, and the administrative bureau. However, you won't hear it at a lively izakaya or during a casual chat about where to go for lunch. Understanding the 'habitat' of this word is key to sounding natural.

Scenario 1: Business Meetings and Emails

When a project scope is finalized, someone will inevitably ask for 'formal consent' to move forward. Phrases like 'ご承諾いただけますでしょうか' (Could we have your consent?) are standard in formal emails.

In these settings, the word acts as a signal that the negotiation phase is over and the implementation phase is beginning. It provides a clear, unambiguous marker of agreement that protects all parties involved. You will also see it in software interfaces—whenever you click 'I Agree' on a Japanese website, the button often says 承諾 or 同意.

Scenario 2: Legal and Administrative Contexts

Government forms, lease agreements, and medical release forms use 承諾 to describe the legal act of giving permission. For example, a 'surgery consent form' is 手術承諾書 (shujutsu shoudakusho).

In these cases, the word is not just a polite way of saying 'yes,' but a legal term that carries specific responsibilities. If you hear a doctor or a lawyer use this word, they are speaking about the formal transfer of rights or the granting of permission for a specific action to take place.

You might also encounter this word in historical dramas or literature when a lord 'consents' to a vassal's request. This usage underscores the hierarchical nature of the word—it is often someone in a position of power or ownership who 'consents' to a request from another. In modern life, this translate to the 'power' of the client or the 'power' of the parent/guardian.

Finally, look for it on official notices. If a store is closing for renovations, they might end their notice with 'ご理解とご承諾をお願い申し上げます' (We ask for your understanding and consent/acceptance), though ご了承 (goryoushou) is more common in that specific 'understanding' context. Knowing the difference helps you navigate the subtleties of Japanese public messaging.

While 承諾する is a useful word, learners often trip up on its formality and its specific nuance compared to other 'agreement' words. The most common mistake is using it in a casual context where it sounds bizarrely stiff.

Mistake 1: Confusing with 賛成 (Sansei)

賛成 means 'I agree with your opinion.' 承諾 means 'I accept your request/offer.' If someone says 'I think we should eat pizza,' you say 賛成, not 承諾.

If you use 承諾 to agree with an opinion, it sounds like you are a king granting permission for that person to have that opinion. It implies a power imbalance that isn't intended. Always ask yourself: 'Am I agreeing with a thought, or am I accepting a formal request?'

Mistake 2: Overusing in Casual Speech

In daily life, use words like 'いいよ' (ii yo), 'わかった' (wakatta), or '了解' (ryoukai). Using 承諾 with friends makes you sound like a legal contract.

Imagine a friend asking, 'Can I borrow your umbrella?' and you responding, 'I formally consent to your request to borrow my umbrella.' It’s funny in a 'robot' way, but not practical. Save 承諾 for situations involving paperwork, superiors, or formal commitments.

Another error involves the particle choice. 承諾 is a transitive verb, so it takes を (wo). However, some learners mistakenly use に (ni) because they are thinking of 'agreeing TO' something. Remember: [Thing] を 承諾する.

Mistake 3: Confusing with 承認 (Shounin)

承認 means 'approval' or 'recognition.' It is often used for internal company processes (like an expense report being approved). 承諾 is more about the agreement between two parties.

While they overlap, 承認 is often a one-way 'stamp of approval' on a document, while 承諾 is the act of saying 'yes' to a proposal or request made by another person or entity. Use 承認 for 'approving' and 承諾 for 'consenting.'

Japanese has a rich vocabulary for 'agreement,' and choosing the right one depends entirely on the context and level of formality. Let's compare 承諾する with its closest relatives.

1. 同意する (Doui suru)

Focus: Agreement of will or opinion. It is very close to 承諾 but slightly broader. You 'agree' (同意) with a policy, but you 'consent' (承諾) to a specific request. In many legal contexts, they are used almost interchangeably, but 承諾 feels slightly more personal (one person asking another).

Example: 'プライバシーポリシーに同意する' (Agree to the privacy policy). This is the standard term for terms and conditions.

2. 了解する (Ryoukai suru)

Focus: Understanding and acceptance of a situation. This is much more common in daily business for 'Roger that' or 'Understood.' It doesn't imply a formal 'consent' so much as 'I have received the information and will act on it.'

Example: '指示の件、了解しました' (Understood the instructions). Note: Be careful using this with superiors; 承知いたしました (shouchi itashimashita) is better.

3. 承知する (Shouchi suru)

Focus: Knowledge and acceptance. This is the humble way to say 'I understand' or 'I will comply.' It doesn't carry the legal weight of 承諾 but is essential for polite business communication.

Example: '承知いたしました。すぐに対応します。' (I understand. I will handle it immediately.) This is your go-to phrase for acknowledging a client's request without necessarily 'consenting' to a contract.

Finally, consider 許可する (kyoka suru), which means 'to permit.' While 承諾 is an agreement between two parties (often equals or business partners), 許可 implies a clear hierarchy where the one giving permission has the authority to deny it (like a government giving a visa or a teacher giving a student permission to leave).
