Adapting explanations for different audiences in Japanese

Practice presenting the same cautious proposal in casual conversation, professional speech, an email and a formal summary. Plain endings and particles such as “よ” and “ね” suit familiar colleagues here, while “です” and “ます” endings suit a more polite workplace exchange. Formal written Japanese can also use plain endings, so plain form alone does not mean casual speech; the supplied summary mixes plain and polite endings, but your own report should normally keep one style consistent. Unlike English, Japanese often leaves an understood “we” unstated, and the email places the possible benefit before the proposal, linking them with “ので,” meaning “because” or “since.”

Action nouns and verbs formed with する

Familiar conversation: a conditional benefit and a shared recommendation

システムを導入すれば、対象を割合くらい減らせると思う。

Polite conversation: possibility with かもしれません

システムを導入すれば、対象を割合ほど減らせるかもしれません。

Professional email: give the reason before proposing an action

対象を割合ほど減らせる可能性があるので、システムを導入(どうにゅう)することを提案します。

Formal summary: noun phrases and less personal recommendations

システムの導入(どうにゅう)で、対象が割合ほど短縮されるかもしれない。

Compare conversation, professional email and formal summary

Keep the same possibility, evidence and approval sequence

“導入することを提案します” turns the action into something proposed using こと, while “システムの導入” uses an action noun; unlike an English verb-to-noun pair, 導入 and 承認 can become verbs by adding する, whereas 減らす and 減少 are not interchangeable in every sentence. In “待ち時間を…減らせる,” waiting time is what someone can reduce, while “待ち時間が…短縮される” makes it the subject of a passive construction meaning “be shortened.” “一割” means ten percent, and くらい, ほど and 約 mark approximation here, with くらい fitting the conversational version and 約 providing compact numerical wording.

“承認してもらう” presents obtaining the department head’s approval from the recipient’s perspective, while “部長の承認を求める” names seeking that approval; “試したほうがいいね” gives familiar advice, and “望ましいと考えられます” presents a less personal professional recommendation. Keep uncertainty through wording such as “減らせると思う,” “可能性がある” or “かもしれない,” and retain the limitation that the estimate comes from testing at one branch for two weeks. Preserve testing at two additional branches before seeking approval for wider implementation, and keep “ただ” or “ただし” attached to the evidence limitation so the reader does not mistake the estimate for an established result.
