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.
