The first thing Vietnamese staff tend to stumble on in a Japanese company is 報連相 (hou-ren-sou) — report, inform, consult. It is a staple of new-employee training in Japan. Vietnamese workplace culture has no exact counterpart.
The habit of reporting unfinished work
Japanese managers often ask: "Why didn't you tell me sooner?" Vietnamese staff often answer: "It wasn't finished, so there was nothing to report yet."
The gap here is not competence, and it is not conscientiousness. The two sides simply draw the line differently on what counts as reportable information.
In most Vietnamese workplaces, the person given a task completes it themselves and presents the result. Sharing a half-finished state can read as "this person can't decide on their own." So people work quietly until it is done.
The Japanese office runs on the opposite premise: sharing mid-stream is the evidence of trustworthiness.
Consulting is the hardest part
Reporting and informing settle in fairly quickly once you fix the procedure. The hard one is 相談 — consulting.
Consulting means spending your manager's time while you still have no answer. Japanese offices encourage exactly this. But where respect for the time of elders and seniors runs deep, walking in empty-handed carries a real psychological cost.
"It took me six months before I could say the words: I don't know."
That is from one of our own team members. Six months is not unusually long.
Fix it with mechanisms, not pep talks
Trying to solve this with appeals to mindset almost always fails. What actually worked for us was distinctly unglamorous:
- Put a number on the reporting threshold. "If you think you'll be more than two hours behind plan, say so at that moment." Not a vague "report early."
- Keep a "what's blocking you" field in the daily report template. It can be left blank — but the existence of the field is itself permission to write something there.
- Have the manager describe their own mistakes first. Whether people feel able to ask is almost entirely determined by whether the manager has admitted to misjudging something.
Not a question of which is better
The thing to avoid is turning this into "the Japanese way is correct." The Vietnamese approach — once it's delegated, it's genuinely delegated — has clear strengths: faster decisions, and stronger ownership from the person doing the work.
The premises differ; neither is superior. The teams that move fastest are the ones that have put both sets of premises into words.
