What the specification means in practice
Japan does not just give you a head-height range and leave the placement to you. The Ministry of Foreign Affairs specifies the whole vertical layout of the 35 × 45 mm frame: 4 ± 2 mm of margin above the head, a head of 34 ± 2 mm from crown to chin, and 7 ± 2 mm from the chin to the bottom edge. Those three add up to 45. There must also be at least 2 mm of clear space on each side of the head.
Reading the specification as a layout, not a range
Because every band is given with a tolerance, the fastest way to check a Japanese photo is from the top down rather than by measuring the head alone. Is there a small but visible margin above the hair? Does the chin sit roughly 7 mm up from the bottom edge? Is there daylight on both sides of the head?
A photo where the head is the right size but sitting too low will fail even though the head-height measurement passes, because the margin above it exceeds 6 mm and the space below the chin drops under 5 mm.
Background: plain, and no gradients
The specification calls for a plain background and explicitly rules out gradients. A studio backdrop that fades from light at the top to darker at the bottom — common in older portrait setups — is not acceptable even though it is a single colour. A flat, evenly lit wall is.
Borderless printing is required. The photo is submitted as a plain 35 × 45 mm rectangle with no white edge around it.
Why the standard is this exact
MOFA notes that the specification follows the ICAO recommendation, and that a passport is the only identity document a traveller carries abroad. It also notes that some destination countries now verify travellers using facial recognition at immigration. The tight layout tolerance is what makes that verification reliable across a document that may be in use for ten years.
The specification was last updated on 3 March 2025, so guidance published before then may not match.
Recency and online applications
The photo must be taken within six months of the application. Applications submitted online have additional file rules on top of the physical specification — file size and format constraints that apply to the uploaded image — and those are published separately for applicants inside Japan and applicants at overseas missions.
If you are having a studio take the photo for an online application, ask for the digital file as well as the prints. Photographing a printed photo with a phone to upload it loses exactly the resolution the standard depends on.
What to check before submitting
Head straight and facing the camera, no tilt. Full face visible, hair not covering the eyes. Even lighting with no shadow on the background — the flat plain background requirement makes shadows especially visible. And the vertical layout: margin above, head, gap below chin.
