Grammar & Usage

formal

How it works

This phrase combines the idiomatic adverbial expression 「一刻も早く」 (ikkoku mo hayaku, meaning 'as quickly as possible' or 'without a moment's delay') with the humble verbal construction 「お知らせします」 (oshirase shimasu). The verb structure uses the humble prefix 「お」 + noun stem 「知らせ」 + polite verb 「します」 to politely refer to the speaker's own act of notifying the listener. It is a standard business formula used to express urgency and a proactive commitment to keep the other party informed.
