Why Japanese Partners Ask for So Much Detail

If you have worked with Japanese clients, customers or colleagues for any length of time, you will probably recognise this situation. I certainly do.


You send a proposal, answer a list of questions and think you are finally close to a decision. Then another email arrives. “Thank you. We have a few additional questions…”

The questions are not difficult. In fact, most are perfectly reasonable. They simply keep coming. More detail. More clarification. More supporting information.


For many people outside Japan, it can feel as though the goalposts are constantly moving. It is easy to conclude that the client is indecisive, overanalysing everything or simply delaying the inevitable.


In many Japanese organisations, however, the request for detail is not a sign that anything has gone wrong. It is often part of the decision-making process itself.


Reducing Uncertainty Before Making a Commitment


Before a significant commitment is made, there is often an expectation that uncertainty should be reduced as much as reasonably possible. That means exploring risks, confirming assumptions and making sure that the people involved have confidence in the decision.


This can result in questions that seem surprisingly detailed to an overseas supplier. What happens if the timetable changes? Who will be responsible for a particular stage? How exactly will an issue be handled? Can you provide another example? Can you clarify something that appeared to have been settled in an earlier conversation?


From the Japanese perspective, asking another question may simply be the responsible thing to do. From the overseas supplier’s perspective, it can feel like the twentieth round of questions about something that was already explained two weeks ago.


Neither side is necessarily being unreasonable. They are approaching risk from different angles.


The Questions May Be for More Than One Person


Another important point is that the person asking the questions may not be the only person who needs the answers.


A proposal may need to be discussed internally with colleagues from different functions, departments or levels of management. Those people may have had little or no direct contact with you. They are therefore relying on the information being circulated internally to understand what is being proposed and what the implications might be.


This helps explain why apparently similar questions can return in slightly different forms. A technical colleague may be concerned about implementation. Someone in procurement may be looking at commercial risk. A senior manager may want reassurance about the overall approach.


The person you are dealing with may therefore be gathering the information needed to build confidence across a wider group.


Why Impatience Can Make Things Worse


The danger comes when frustration starts to show.


If you begin answering more briefly, responding more slowly or signalling that a question has already been answered, you may unintentionally create exactly the concern the client is trying to remove.


If the supplier becomes impatient during the decision-making stage, what will they be like when there is a genuine problem later? That does not mean you should accept an endless process without question. Commercially, there will always be a point at which you need to understand whether an opportunity is genuinely progressing.


But there is a difference between managing the process and becoming visibly frustrated with it.


Make It Easier for the Client to Reach a Decision


Rather than treating each new question as an isolated request, it can help to think about what sits behind it.


If you are repeatedly being asked for clarification, perhaps the client needs a more structured explanation. If several questions concern implementation, provide a clear implementation plan. If risk appears to be the underlying concern, address the likely risks directly rather than waiting for each one to become another question.


Written information can also be particularly useful. A clear document can be shared internally and referred back to later, making it easier for your contact to explain and support your proposal inside the organisation.


This is one reason a well-structured proposal can matter so much when working with Japanese organisations. It is not simply a sales document. It can become part of the internal decision-making process.


The Decision May Come Later Than You Expect


One of the more difficult aspects for overseas suppliers is that all this activity does not necessarily look like progress. There may be no obvious negotiation, no clear indication that approval is getting closer and very little of the internal discussion is visible to you.


Then, after weeks of questions, the decision arrives.


What looked from outside like hesitation may actually have been a considerable amount of internal work. Understanding that does not make every lengthy decision process commercially acceptable, nor does it mean every Japanese organisation behaves in the same way. But it does help explain why requests for detail can continue long after an overseas supplier feels enough information has already been provided.


Sometimes the additional question really is just another question.


And answering it properly may be one more small step towards the decision.
