失礼します。 — Excuse me (may I enter). (Workplace · Greeting, Formal to Superior, JLPT N5)

Gesture & etiquette

Knock 3 times before opening. Wait for response. Open door slowly, bow (15°) at the doorway while saying the phrase, then enter and close the door quietly with your hand still on the handle. Say 'shitsurei shimasu' again when leaving the room.

失礼します literally means 'I will be rude' — asking permission to disturb. Said when entering and leaving meeting rooms, a manager's office, or any closed-door workspace. Critical knock protocol: 3 knocks = visiting / asking entry; 2 = checking if occupied; 4+ knocks = funeral context, avoid. Always close doors quietly behind you.
