Grammar & Usage

fixed expression

formal

How it works

This expression combines the idiomatic adverbial phrase '一刻も早く' (as quickly as possible / without a moment's delay) with the polite request pattern 'ご[noun]ください'. The prefix 'ご' (go-) adds respect to the Sino-Japanese verbal noun '連絡' (renraku, contact). It conveys a strong sense of urgency while maintaining polite business etiquette.
