終了をする

Use 終了をする when you are the one in charge of ending something. You might announce the end of a meeting, a class, or a presentation. It’s also used for formal processes, like ending a contract or a period of service. The structure is usually [Noun] + を + 終了をする. The noun is the thing being ended. For example, 会議を終了をする (kaigi o shūryō o suru) means to end the meeting. It's a bit more formal than just saying 終わる (owaru), which means 'to end' more generally. This phrase adds a layer of official action.

Imagine you're watching a business seminar online. The speaker might say, 本日のセミナーを終了をいたします (Honjitsu no semina o shūryō o itashimasu), meaning 'We will now end today's seminar.' Or a teacher might tell their class, これで授業を終了をします (Kore de jugyō o shūryō o shimasu), 'We will now end the class.' Even in a video game, a developer might announce, イベント期間を終了をします (Ibento kikan o shūryō o shimasu), 'We will end the event period.' It’s about that definitive stop.

This phrase shines in professional or official settings. Think of ending a formal meeting, a business presentation, a seminar, or a workshop. It’s perfect for announcements where you need to clearly state that something is concluding. You can also use it for official processes like ending a subscription or a service period. If you're a project manager wrapping up a phase, this is your go-to. It sounds decisive and organized. It’s the polite way to say, 'Okay, that's a wrap!' without sounding too casual.

Don't use 終了をする for everyday, casual endings. If your friend is telling a story and finishes, you wouldn't say その話は終了をした (Sono hanashi wa shūryō o shita). You’d just say 終わった (owatta). It’s also too formal for personal feelings or informal situations. Ending your lunch break isn't usually a 終了をする moment unless your boss specifically announces it that way. Avoid it for spontaneous events or when something naturally concludes without a formal declaration. It’s not for when your pizza delivery is 'over' (finished arriving).

A big mistake is using it too casually. Saying 私の休憩を終了をする (Watashi no kyūkei o shūryō o suru) in a casual office chat sounds stiff. Also, mixing it up with 終わる (owaru) or 終える (oeru) can be tricky. 終わる is often intransitive (something ends by itself), while 終える is transitive (you end something). 終了をする is a more active, formal verb phrase. Using 終了 as a verb directly without をする can also sound incomplete in some contexts. It's like trying to use 'conclusion' as a verb in English – it needs a helper!

• 終わる (owaru): The most common verb for 'to end'. It's neutral and can be used in most situations, both formal and informal. It often implies something ending naturally. 会議が終わる (Kaigi ga owaru) - The meeting ends.
• 終える (oeru): Also means 'to end' or 'to finish', but it's transitive, meaning you actively finish something. 宿題を終えた (Shukudai o oeta) - I finished my homework. It's less formal than 終了をする.
• 締めくくる (shimekuru): To wrap up, conclude, or round off. Often used for speeches, performances, or periods. イベントを締めくくる (Ibento o shimekuru) - To wrap up the event. It has a more conclusive, summing-up feel.
• 完了する (kanryō suru): To complete. This emphasizes the successful finishing of a task or process, often with a sense of accomplishment. プロジェクトを完了する (Purojekuto o kanryō suru) - To complete the project.

The most common variation is using the polite 〜いたします (itashimasu) or 〜します (shimasu) endings. So, instead of 終了をする, you'll often hear 終了をいたします (shūryō o itashimasu) or 終了をします (shūryō o shimasu). These sound more polished and are standard in polite announcements. Sometimes, especially in very formal written announcements, you might see 終了 used as a noun followed by a verb like 行う (okonau - to perform), like 終了を行う (shūryō o okonau), but this is quite rare and formal. It's like saying 'perform the conclusion'.
