Gesture & etiquette
Bow at 15-30 degrees depending on relationship. In person, this greeting often accompanies a final bow before parting for the holiday season. In business, send this phrase in emails and cards in the final week of December.
Used from mid-December through December 31 — never on January 1st (switch to 'akemashite omedetō' then). Both halves are essential: reflecting on the past year's relationship and wishing for a good new year. This paired structure is standard in both business and personal relationships.
