Verbatim official spec

Below is the verbatim official spec from the Tokyo Metropolitan Police Department recruitment guide (Japanese). Each of the 47 prefectural police forces sets its own rules, so always check the latest guide of the force you are applying to.

  • 写真は、4㎝×3㎝、上半身、無帽、正面向き、6か月以内に撮影したものを使用してください。また、写真の裏面に、氏名を記入してください。

Why this spec matters

Japan has no single national police force — recruitment is run separately by each of the 47 prefectural police forces. This page uses the Tokyo Metropolitan Police (Keishicho) guide as a representative example, but the force you are applying to may have different requirements. Always read its current recruitment guide. Police recruitment screens identity strictly, and a non-compliant photo can disqualify you before the written exam: candidates have been turned away for oversized photos, expired shots (older than 6 months), or missing back-side name.

How to create it for ¥200

A police-exam-compliant ID photo takes about two minutes with a smartphone and ¥200. Always cross-check with the recruitment guide of the prefectural police you are applying to.

  1. 1

    Take the photo on your smartphone

    Stand against a plain wall in a bright room. Face the camera directly, no hat, composed expression, shoulders level, eyes on the lens.
  2. 2

    AI removes background and aligns to spec

    Upload the photo. AI removes the background, detects your face, and auto-crops to the 30×40mm spec. Fine-tune the position to 0.1mm precision.
  3. 3

    Print at a convenience store, then write your name on the back

    After payment, a QR code and 8-digit user number arrive by email. Print on L-size paper at any Japan convenience store from ¥30. Write your name on the back of the print before pasting it to the application form.

Frequently asked questions

Do photo rules differ between Tokyo Metropolitan Police and, say, Osaka Prefectural Police?
Yes. Each of the 47 prefectural police forces issues its own recruitment guide, and details like size, freshness window, and back-side name rules can vary. The common baseline is 30×40mm, within 6 months, upper body, no hat, front-facing — but always check the latest guide of the specific force you are applying to. This page documents the Tokyo Metropolitan Police rules as a representative example.
Is writing my name on the back of the photo mandatory?
Yes for the Tokyo Metropolitan Police and many other prefectural forces. It is required so that you can be identified if the photo separates from the application packet. Write your name with a ballpoint pen before pasting the photo. Forgetting can be treated as an incomplete application.
Will a smartphone + AI photo be accepted?
Generally yes, as long as the photo meets the spec (size, freshness, no hat, front-facing, upper body). Ramune AI ID Photo auto-crops and adjusts to spec, producing a result equivalent in quality to a photo studio. If the guide explicitly says "taken at a photo studio or photo booth," follow that instruction.
Can I wear glasses?
Usually allowed if the lenses are clear with no reflection or tint, but police recruitment screens identity strictly. If lenses obscure the eyes or there is any reflection from lights or your phone screen, removal is safer. Reflections almost always cause rejection.
Does the background have to be white?
The Tokyo Metropolitan Police guide does not specify a color, but plain white or very light gray is the safe convention. Some prefectural forces may specify "blue" or "gray" — check the latest guide of the force you are applying to.
