Why Japanese suppliers do not reply to overseas inquiries, and how to write one that gets answered
Updated · Hikaru Amishiki, Representative Member, HAM LLC.
Overseas buyers often describe the same situation: they found a Japanese manufacturer with exactly the part or product they need, sent an email in English, and heard nothing back. It is rarely a sign that the company is not interested. More often the inquiry never reached someone who could answer it, or it did not contain enough to act on.
This guide explains what usually happens on the Japanese side and how to write a first inquiry that a small or mid-sized Japanese manufacturer can actually respond to.
What usually happens on the Japanese side
Most Japanese manufacturers that overseas buyers find online are small or mid-sized companies focused on domestic customers. A message sent to the general contact address on their website typically lands with an administrative or domestic sales person, not with someone who handles exports.
From there, several things can stop the reply:
- Nobody on the team is confident writing in English, so the message waits for someone who is.
- The inquiry does not say what the item is for, how many are needed, or when, so it cannot be priced and is treated as a general request for information.
- The company has little or no export experience and is unsure about shipping, payment, and export paperwork, so it hesitates rather than replying with questions.
- Existing domestic customers take priority, and an unknown overseas sender with a vague request is put aside.
Five details that make an inquiry answerable
A short, specific inquiry is far more likely to be forwarded to the right person and answered. Include the following in the first message.
- Who you are: company name, your role, the country you buy from, and a website or company profile the supplier can check.
- What the item is and what it is for: the product, part, or material, and the machine, process, or end product it goes into.
- A drawing, specification, photo, or reference part number. If you only have the nameplate of a machine, send that.
- Quantity now and expected volume over a year, even as a range. Suppliers price differently for a one-off and for repeat orders.
- Destination country, required timing, and whether you already have a supplier for this item.
Format that helps
Keep the subject line concrete, for example the part type and quantity rather than a general greeting. Put one item per inquiry; a list of unrelated requests is hard to route inside the company.
Say how you found the supplier and why you think they fit, in one sentence. Avoid asking for a full catalogue or a price list as the first step; ask for a quotation on the specific item instead. Plain, short sentences are easier for a non-native reader than polished business English.
If there is still no reply
Allow five to ten business days before following up. Japanese companies also close for several days around Golden Week in late April and early May, the Obon period in mid-August, and the year-end and New Year holidays, so a message sent just before those periods can wait two weeks.
Send one follow-up that repeats the key facts in a few lines. If the second message also goes unanswered, the practical route is a Japan-side coordinator who can call the company, confirm in Japanese whether they can supply the item and export it, and bring the answer back to you.
How HAM handles this
When an overseas buyer contacts HAM, we first confirm the item, intended use, specifications, quantity, timing, and destination with you in English. We then approach candidate Japanese suppliers in Japanese with a structured summary of your requirement, and we confirm with them whether they can supply, on what lead time, and with which export documents.
We reply to you by the next business day, and we tell you plainly when a supplier cannot be found or cannot export.
Frequently asked questions
- Do I need to write in Japanese?
- No. A specific English inquiry is usually enough for the supplier to understand the request. Japanese helps when the company has no English speaker, which is common among small manufacturers, and that is one of the things a Japan-side coordinator does for you.
- Do Japanese suppliers accept small orders?
- It depends on the item and the supplier. Minimum quantities are often driven by setup or tooling cost rather than policy, so a sample or small first order is sometimes possible at a different unit price. Ask rather than assume.
- How long does a first quotation take?
- It varies with the item. A stock item can be quoted in days; a made-to-order part may need drawings reviewed by an engineer first. HAM confirms the supplier's expected timing before you wait on it.
