Verbatim official spec
Below is the verbatim official spec from the Doboku Seko exam guide published by the Japan Construction Training Center (JCTC), shown in the original Japanese. The same spec applies to both Class-1 and Class-2.
- 「正面上半身像の高さと幅の比率が概ね4:3」
- 「申請日から6ヵ月以内に撮影したもの(白黒でも可)」
- 「正面、無背景、鮮明であること(焦点が合っていること)」
- 「明るさやコントラストが適切で影のないもの」
- 「前髪で目元や輪郭が隠れていないこと / 眼鏡の光の反射やフレームが目にかかっていないこと」
- 「サングラスやマスク、帽子等を着用していないもの / 笑顔でないもの(歯が見えていないもの)」
Why this spec matters
Civil Engineering Construction Management Engineer (土木施工管理技士) is a national qualification under the Construction Business Act, covering roads, bridges, tunnels, rivers, and other infrastructure work. Roughly 30,000 candidates per year take Class-1 or Class-2 — many are working construction-site engineers. The application photo must follow the official spec: "upper-body portrait at roughly 4:3 ratio", "taken within 6 months of application (B&W allowed)", "front-facing, plain background, sharp focus", and "no smile (teeth not visible)" — otherwise the upload is rejected. Note: this is a different qualification from Building Construction Management Engineer Class-1/2 (administered by FCIP) — same Construction Business Act but different issuing bodies. The print size happens to be the same 35×45mm, but the submission systems differ, so check this page before reusing photos. JCTC also administers Pipe Construction Management Engineer, which shares the exact same photo spec.
