How to Write an RFQ to a Japanese Supplier

A first message may reach a general mailbox, domestic sales desk, engineer, distributor contact, or administrator. In the opening lines, identify your company and country, the product family, whether the request concerns supply, identification or custom manufacture, the destination, and the requested action. Mention the official page, product or referral that led you there so the recipient can judge relevance.

Do not imitate ceremonial Japanese business language or hide the request inside a long company introduction. Plain, respectful English is workable when the structure is clear. If the recipient is not responsible, explicitly ask for forwarding to the export, product or sales contact—or for a short decline. That gives the first reader a safe action.

For catalogue parts, provide manufacturer, complete code including suffix, clear label and item photographs, host machine, function, installed revision, required accessories, desired condition and whether alternatives may be proposed. If identity is uncertain, say that the request is for identification and list the evidence available. Do not put an uncertain guess into a mandatory part-number field.

For custom work, attach a controlled drawing or requirement with revision, units, material, treatments, tolerances, inspection, standards, quantity, annual demand, sample or tooling needs, and approved file formats. Remove unrelated confidential data. State which characteristics are mandatory, which can be discussed, and who will answer technical questions.

Number the requested fields: offered manufacturer and code, condition, quantity and MOQ, unit and total price, currency, validity, stock or production basis, lead-time start event, Incoterms rule with named place, packing, export documents, payment timing, warranty or return process, and deviations. Ask candidates to mark Unknown rather than fill gaps with assumptions.

Request evidence appropriate to the item: current photographs, manufacturer traceability, certificates, inspection records, material reports, or a written statement of seller role. Avoid demanding every possible certificate. An unfocused list creates work without proving the property your engineers or compliance owners actually need.

If there is no response, verify the address and supplier fit before resending. A short follow-up should reference the original subject and date, restate the one requested action, and offer a smaller next step: confirm the right department, advise whether the item is handled, or decline. If new information changes the requirement, issue a visible revision rather than silently altering the email chain.

HAM can help turn a requirement into a concise bilingual-ready enquiry, identify an appropriate Japan-side route, and organise replies and open questions. The buyer remains responsible for technical acceptance, supplier approval, commercial agreement, compliance, and release of any order or payment.
