Why this spec matters

Class-1 Building Construction Management Engineer (1 級建築施工管理技士) is a national qualification under the Construction Business Act, with roughly 40,000 candidates per year — one of the largest construction-industry exams in Japan. The application photo must follow passport-style spec (JPEG, 531×413 px), be taken within 6 months, and show a plain background with no hat or accessories — otherwise the upload is rejected. Note: this exam (administered by FCIP, under the Construction Business Act) is a separate qualification from Architect Exams (administered by JAEIC, under the Architect Act). The print size is coincidentally 35×45mm for both, but the digital pixel sizes and submission systems differ, so always check this page before reusing an architect-exam photo.

How to create it for ¥200

A spec-compliant Kenchiku Seko Class-1 application photo takes about two minutes with a smartphone and ¥200.

  1. 1

    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 accessories, neutral expression, eyes on the lens. Clear-lens glasses are okay but watch for reflections.
  2. 2

    AI removes background and resizes to 531×413 px JPEG

    Upload the photo. AI removes the background, detects your face, and auto-crops to FCIP spec (35×45mm / 531×413 px), then exports as JPEG.
  3. 3

    Get both a digital JPEG and a convenience-store print QR

    After payment, a QR code and 8-digit user number arrive by email. Download the JPEG for digital submission, and print L-size from ¥30 at 7-Eleven, FamilyMart, Lawson, Ministop, and Poplar nationwide.

Frequently asked questions

Can I reuse my Architect Exam photo for the Kenchiku Seko Exam?
Not directly. Architect exams (JAEIC) use 665×915 px digital, while Kenchiku Seko (FCIP) uses 531×413 px — the pixel sizes differ. The 35×45mm print size happens to match, but they are separate qualifications under different laws and use different submission systems, so re-export at this page's spec.
Can I submit an HEIC file from my iPhone?
Not directly. The official spec explicitly requires JPEG, and HEIC files are rejected. Ramune AI ID Photo auto-exports as JPEG at 531×413 px, so any phone format works as input.
Do I need a digital file, a printed photo, or both?
Class-1 Kenchiku Seko applications are submitted online, so the digital JPEG (531×413 px) is the required file. A printed photo is not formally needed, but many candidates bring an L-size print on exam day as a backup ID — having the konbini print ready is good practice.
Is the photo spec the same for Class-1 and Class-2?
Yes. Both Class-1 and Class-2 Building Construction Management Engineer exams, administered by FCIP, share the same photo spec — print 35×45mm, digital 531×413 px JPEG, within 6 months. Only the exam level and schedule differ.
Can I reuse the same photo for the Electrical Construction Management exam?
Yes. The Electrical Construction Management Engineer Exam is also administered by FCIP and uses the same photo submission page and spec (JPEG 531×413 px, within 6 months, plain background, no hat or accessories). If your photo is still within 6 months, you can submit the same file to both exams.
