Workplace 

Being late is considered impolite; however, arriving too early is also inappropriate; arriving 5-10 minutes early is standard.

This applies to online meetings as well.

Face the card toward the receiver, hand it over with both hands, and bow.

Read and appreciate the card before putting it into a business card holder.

Men usually wear dark suits with white shirts; women should dress conservatively.

Shoes should be clean, and indoor slippers may be required in some offices. 

Bow deeper (30–45 degrees) to superiors and clients.

A small nod is enough between coworkers.

(15 degrees)

Japanese meetings follow a turn-taking system; interruptions are impolite.

Even disagreement should be expressed with care.

Saying “No” directly is avoided.

Phrases like “I’ll think about it” or “That may be difficult at the moment” are used.

At a meeting or dinner, seating is arranged according to status.

The seats farthest from the door are for guests or superiors, and the seats closest to the door are for new employees.

It’s polite to say"お先に失礼します " to colleagues still working.

They will respond with “お疲れ様です ” to acknowledge your effort. 

Even if the mission is accomplished, staying longer is considered dedication.

Being the first to leave can be uncomfortable.

After-get off work drinking parties and dinners don't count as work time, but they are still part of workplace culture.

Be polite, don't get drunk, and let your superiors take the lead when toasting or speaking.
