Diploma Apostille for Japan Work Visa — Japan HSP Points System Guide

Submitting your university diploma for a skilled worker or employment visa application in Japan requires more than a notarized photocopy. Receiving authorities in Japan verify documents through an internationally agreed apostille procedure that ties your original record to a recognized state authority in the country of issuance. The order in which the steps are performed matters: a translation completed before the apostille is added is usually rejected, and missing the prior state-level authentication is the single most common reason Japan returns documents unprocessed.

What this service includes for Japan

Authentication authority for Japan

Documents bound for Japan are authenticated through the Ministry of Foreign Affairs of Japan, which has issued Hague Apostilles since 1970. Because both Japan and most likely the country where the document was issued are members of the 1961 Hague Apostille Convention, a single apostille certificate is sufficient — no embassy legalization is needed.

How DoCertify processes your diploma

  1. Free eligibility check. We confirm that your university diploma qualifies for an apostille from the Ministry of Foreign Affairs of Japan, which has issued Hague Apostilles since 1970, and flag any pre-step (notarization, state-level certification) needed first.
  2. Document intake. You ship the original record to our processing office, or we collect it from your address by courier. Scans are accepted only for documents that the issuing authority will re-print on demand.
  3. Apostille issuance. Our team submits the document to the Ministry of Foreign Affairs of Japan, which has issued Hague Apostilles since 1970, monitors the queue and retrieves the apostille — typically in 3–7 working days for standard processing, or 24–48 hours for urgent service where available.
  4. Certified translation (optional). If Japan requires the document in another language, we add a sworn translation that satisfies Japan's receiving authorities.
  5. Delivery. The apostilled document is returned to you with tracked international courier, or — when accepted — sent directly to your destination institution in Japan.

Frequently asked questions

What is the most common reason Japan rejects a foreign diploma?

Three issues account for most rejections: (1) the apostille is missing or was issued by a non-competent authority; (2) the translation was completed by a translator not recognized in Japan; (3) the order of operations was wrong — for example, a translation produced before the apostille was added, leaving the apostille text untranslated. We sequence the chain correctly the first time.

Can I submit a digitally signed or scanned diploma?

Generally no. Japan authorities for skilled worker or employment visa application purposes require the physical original or a re-issued certified true copy bearing a wet-ink stamp from the issuing institution. Digital-only documents are accepted only for a narrow set of issuers that publish a verifiable online register.

How long does the apostille process take for Japan?

Standard turnaround for apostille of your university diploma bound for Japan is 3–7 working days from the moment we receive the original document. Urgent processing is available in 24–48 hours for most countries of origin where the issuing authority offers expedited service.

Do I need to be in Japan to start the process?

No. The entire apostille chain is processed in the country where your university diploma was issued, not in Japan. You only need to ship the original document to our processing office; the apostilled and translated package is then couriered to wherever you are.

Employers and skilled-worker visa officers in Japan sit on dozens of applications per week. A document chain that arrives correctly authenticated and translated the first time moves through the queue faster, while a chain with a missing step is set aside and often only flagged after weeks of waiting. We process your university diploma so that the work-visa decision-maker can verify it on first inspection.
