Verbatim official spec

The verbatim official spec from Japan's Digital Agency and J-LIS is shown below in the original Japanese.

  • 「縦4.5cm×横3.5cm」
  • 「写真の両端から顔の中心まで（横）17±2」
  • 「顔縦34±2」
  • 「頭の頂点から写真の上端4±2」
  • 「正面、無帽、無背景のもの」

Why this spec matters

According to Japan's Digital Agency, nearly 80% of rejected online My Number applications fail because of photo issues. The tolerance window — 4mm wide for face length (32–36mm) and another 4mm for top margin (2–6mm) — is too narrow to judge by eye on a phone screen.

How to create it for ¥200

A spec-compliant My Number photo takes about two minutes with a smartphone and ¥200.

  1. 1

    Take the photo on your smartphone

    Stand against a plain wall in a bright room. Face the camera directly, no hat, neutral expression or slight smile, eyes on the lens.
  2. 2

    AI removes the background and aligns to spec

    Upload the photo. AI removes the background, detects your face, and auto-crops to My Number rules. Fine-tune position to 0.1mm precision.
  3. 3

    Print at any Japan convenience store via QR code

    After payment, a QR code and 8-digit user number arrive by email. At Lawson, FamilyMart, Ministop, and Poplar, just hold the QR code to the multi-copy machine (L size from ¥30). For 7-Eleven, register the image with netprint first.

What Ramune AI ID Photo offers

Even for a tight spec like My Number, you can finish the entire shoot → process → print workflow in your browser.

Cropping screen with horizontal and vertical guidelines to adjust face position, width, hairline, and chin in 0.1mm units

0.1mm face position adjustment

Drag the hairline, chin, and face-width guides — or type the millimetre value — to fit inside even a 4mm-wide regulatory window like the My Number spec.

Auto-generated L-size print sheet

Multiple photos optimally arranged on L-size paper with cut marks. Print directly at home or at a convenience store.

AI removes the background automatically

Walls or objects in the original shot are auto-removed; AI converts the photo to the plain background the spec requires.

Frequently asked questions

What are the online-application file requirements — can I upload this as-is?
The My Number card online application requires the photo file to be 480–6000 px per side, 20KB–7MB, JPEG (HEIC rejected), RGB color. The surprising trap is the 480 px minimum — output from common ID-photo apps and screenshots can fall below it. Ramune exports the digital file at 1063×827 px, JPEG, RGB, clearing every condition with room to spare, ready to upload as-is.
Can I keep my glasses on for a My Number photo?
Clear lenses with no reflection or tint are allowed. If light fixtures or your phone screen are reflected in the lenses, the photo will be rejected — remove glasses if unsure.
What happens if face length exceeds 36mm?
The submission gets rejected as a spec violation. Ramune AI ID Photo lets you adjust face position to 0.1mm precision, so even a slightly oversized shot can be brought back within range.
How recent does the photo need to be?
It must be taken within the 6 months before your application date. Older photos are rejected as out-of-date.
Can hair cover the face outline?
Forehead, both eyebrows, and the facial outline must remain visible. Light front fringe is fine; full coverage of forehead or eyebrows is rejected.
What if my photo was the wrong size and got rejected?
No re-shoot needed. Upload your smartphone photo and AI auto-adjusts it to the correct spec in about 2 minutes. Preview free, pay ¥200 only if you like it, full refund if it's rejected — avoiding the 1–2 week loss of a counter re-shoot and re-application.
