Supporting a visa application in Japan — what translation and certification is expected?

The scope of this answer is “Supporting a visa application in Japan”, so the answer below starts with what this case actually needs before setting out the general rules. Check first whether the issuing office of the source document is one the destination recognises. The deciding factor is the receiving body's requirement, not only the format of the Thai-side document. Before starting, count the number of certified sets needed before work starts, because extra sets restart the certification steps, then verify the source document is still within any validity window the recipient applies, then check that names are spelled identically to the passport or ID card on every page. The specifics here are purpose: Visa; destination: Jp, and those decide which translation and certification level applies. The terms that frame this page are Supporting · visa · application · Japan. The next step is confirming the filing channel and the copy or file format required. Documents with a short validity window should be produced as close to the filing date as possible. Leave buffer time in case a translation has to be amended or a source document re-issued. Attach a document index to the bundle so nothing is lost during review. Keep a copy of every source document plus the receipt or docket from each step. A Thai-issued medical document intended for a foreign authority normally follows this order: obtain the original from the facility, have it translated by a translator the destination accepts, certify the translation at the Legalisation Division, Department of Consular Affairs, Ministry of Foreign Affairs, then obtain the destination embassy's attestation where required. Each step verifies only what falls within its own authority. A medical translation must preserve the diagnosis, disease codes, drug names, dosages, units and result values exactly as written — no rounding, no unit conversion, no summarising. Where the original is illegible handwriting, the facility should be asked for a typed version or a written confirmation rather than the meaning being guessed. ILC handles document work only — translation, certification of the translation, notarial signature certification and the legalisation run at the Ministry of Foreign Affairs and embassies. ILC is not a medical facility or an insurer, gives no clinical advice, and cannot guarantee any authority's decision. Cost and lead time depend on page count, the density of clinical terminology, the target language and the certification steps required, so every file is quoted before work starts.
