The core meaning
確認でき次第、ご連絡します means 'I will contact you as soon as I can confirm it.' The phrase suits a professional update when the first event is pending and the speaker commits to act afterward. It focuses on a handoff: information arrives, preparation finishes, or a result becomes known; then a response follows without unnecessary delay.
| Japanese | Romaji | Meaning |
|---|---|---|
| 確認でき次第、ご連絡します。 | Kakunin deki shidai, go-renraku shimasu. | I will contact you as soon as I can confirm it. |
| 資料が届き次第、送ります。 | Shiryō ga todoki shidai, okurimasu. | I will send it as soon as the documents arrive. |
How to form it
Attach 次第 to the verb's ます stem: 分かります → 分かり次第, 届きます → 届き次第, 確認できます → 確認でき次第. Do not use the plain past form here. A different construction, noun + 次第, means 'depending on' or 'up to', as in 結果次第です. Keep these two uses separate.
| Use | Japanese form | Meaning |
|---|---|---|
| Verb stem | 分かり次第 | As soon as I know |
| Potential stem | 確認でき次第 | As soon as I can confirm |
| Different use | 結果次第です | It depends on the result |
Natural examples
Read each sentence for the relationship between the first idea and the second. The English translation gives a natural meaning, while the Japanese wording shows exactly where the pattern attaches.
| Japanese | Romaji | Meaning |
|---|---|---|
| 会議が終わり次第、電話します。 | Kaigi ga owari shidai, denwa shimasu. | I will call as soon as the meeting ends. |
| 準備が整い次第、始めましょう。 | Junbi ga totonoi shidai, hajimemashō. | Let's begin as soon as everything is ready. |
Compare the nearby pattern
結果が分かったら連絡します is a natural everyday promise. 結果が分かり次第連絡します sounds more formal and stresses prompt action. たとたんに describes a sudden event at the instant something ends, often outside the speaker's control; 次第 is suitable for a planned response.
| Japanese | Romaji | Meaning |
|---|---|---|
| 結果が分かったら連絡します。 | Kekka ga wakattara renraku shimasu. | I will contact you when I know the result. |
| 結果が分かり次第、ご連絡します。 | Kekka ga wakari shidai, go-renraku shimasu. | I will contact you promptly as soon as the result is known. |
The two examples may describe similar situations, but they lead the listener to different conclusions. Choose the form that matches the claim you really intend to make.
Common mistake to avoid
Do not write 分かった次第、連絡します. The 'as soon as' construction takes the ます stem: 分かり次第. Also do not confuse 結果次第で決める, 'decide depending on the result', with 結果が分かり次第決める, 'decide as soon as the result is known'.
- Pending event followed by prompt action
- Verb ます stem + 次第
- Common in polite updates
- Noun + 次第 has a different meaning
Try it yourself
Draft a polite update about a pending document or decision. Promise one action with verb-stem 次第. Then write the same message with たら and compare the register.
Say your sentence once slowly while looking at the Japanese pattern. Then say it again without reading. If your second clause changes from a possibility to a fact, or from advice to a requirement, revise it so the grammar still matches your meaning.
