Gesture & etiquette
Bow slightly as you re-enter the office; move to key colleagues' desks to greet them individually; deliver a brief summary to your supervisor promptly rather than waiting until the next formal meeting.
Properly greeting colleagues when returning from a business trip ('ただいま戻りました') is expected etiquette — going straight to your desk without acknowledging colleagues can seem cold; a brief trip outcome summary to your supervisor is also expected promptly.
