Verbatim official spec
Below is the verbatim official spec from the Kanko 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」
- 「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
Pipe Construction Management Engineer (管工事施工管理技士) is a national qualification under the Construction Business Act, covering installation management for HVAC, plumbing, sanitary fixtures, and gas systems — the "piping" side of building construction. Roughly 16,000-20,000 candidates per year take Class-1 or Class-2 combined (FY2024 figures: ~8,700 for Class-1 second-stage + ~7,500 for Class-2) — many are working engineers at MEP contractors. The application photo must follow the official spec: "upper-body portrait at roughly 4:3 ratio", "taken within 6 months (B&W allowed)", "front-facing, plain background, sharp focus", and "no smile (teeth not visible)" — otherwise the upload is rejected. The Civil Engineering Construction Management Engineer exam, administered by the same JCTC, shares the exact same submission page and photo spec — if your photo is within 6 months, you can submit the same file to both exams (the exam categories themselves differ: civil engineering vs. piping). Note that the similarly named Building Construction Management Engineer (Class-1 and Class-2 alike) is administered by a different testing body (FCIP) with a different application system — the print size is coincidentally 35×45mm but the smile rule and submission flow differ, so reusing photos is not recommended. Follow this page's spec instead.
How to create it for ¥200
A spec-compliant Kanko Seko (Class-1/2) application photo takes about two minutes with a smartphone and ¥200.

Take the photo on your smartphone
Stand against a plain white or light-colored wall in a bright room. Face the camera directly — no hat, no mask/sunglasses, neutral expression (no visible teeth), eyes on the lens. Clear-lens glasses are okay but watch for reflections. - 2
AI removes background and resizes to 4:3 ratio 35×45mm
Upload the photo. AI removes the background, detects your face, and auto-crops to the JCTC spec (4:3 ratio, 35×45mm equivalent), with brightness and contrast adjusted appropriately. - 3
