Gesture & etiquette
Have pen and paper or a computer ready. Speak clearly and at a gentle pace. After receiving the information, confirm it back: '○○様でいらっしゃいますね' (So you are Mr./Ms. ○○, is that correct?).
恐れ入りますが' (I humbly apologize for the trouble) softens any request that could feel intrusive. Always confirm caller details in writing and read them back to prevent errors. Speak at a measured pace — rushing when recording names causes mistakes.
