Gesture & etiquette
(Email/In-person) In a face-to-face apology, bow deeply — 45 degrees or more — and hold until the other party responds. Do not explain before apologizing; explanation before apology reads as excuse-making.
Japanese business apologies must be immediate, explicit, and unconditional — never begin with excuses or explanations. 'Makoto ni moushiwake gozaimasen' (truly, there is no excuse) is the highest-register apology phrase. Follow it with a clear account of what happened and concrete remediation steps.
