What Does ‘Chi-koku’ Mean? The Ultimate Guide to Japan’s Business Etiquette for Punctuality

Chi-koku (遅刻) refers to the act of being late or tardy. In the context of Japanese business, it is more than just a minor inconvenience; it is often viewed as a lack of professionalism and a failure to respect the time of others, which can significantly damage your credibility and trust with colleagues and clients.

Punctuality is a pillar of Japanese society. Arriving exactly on time is considered ‘late’ in many formal business settings, where being five to ten minutes early is the standard. If you find yourself in a situation where you are unable to avoid Chi-koku, how you handle the communication is vital.

Employee: “Moushiwake gozaimasu. Densha no chien ni yori, go-fun hodo chi-koku shite shimaimasu.”

Translation: “I am terribly sorry. Due to a train delay, I will be late by approximately five minutes.”

When you anticipate being late, always contact your manager or business partner immediately. Using the phrase ‘chi-koku’ directly might sound blunt, so it is often better to use polite language to express the delay, such as ‘okureru’ (to be late) combined with a sincere apology.

Pro-Tip: If your lateness is due to a train delay, be sure to ask the station staff for a chien shoumeisho (a delay certificate). In Japanese corporate culture, this is the gold standard for proving your absence or lateness was truly outside of your control.
