Verbatim official spec
The verbatim official spec from the National Personnel Authority's 2026 exam guide is shown below in the original Japanese.
- 「本人であることが明瞭に確認できる写真(6か月以内に撮影した、脱帽・上半身・正面向きの縦4cm 横3cm のもの。カラー、白黒どちらでも可)」
Why this spec matters
The Japan civil-servant exam (Kokka Komuin Shiken) photo is checked at the application-intake stage, well before any interview. A spec failure means your application is not accepted, or you are asked to resubmit — and if the deadline passes, you lose the entire exam cycle. Treating this as a stricter gate than the interview itself is the right mental model. Online applications are especially prone to slipping through with wrong aspect ratios that only become visible when printed.
How to create it for ¥200
A spec-compliant Japan civil-servant exam photo takes about two minutes with a smartphone and ¥200.
