Verbatim official spec
Below is the verbatim official spec from the Tokyo Examination Guide (Reiwa 8) published by the Hazardous Materials Engineer Examination Center, shown in the original Japanese. The same spec applies to every class (Class A, Class B 1-6, Class C) nationwide.
- 「大きさ 縦 4.5cm×横 3.5cm」
- 「正面、無帽（宗教上又は医療上の理由がある場合を除く。）、無背景の上三分身像又はパスポート規格」
- 「枠なし、鮮明なもの（カラー・白黒どちらも可）」
- 「裏面に氏名、年齢及び撮影年月日を記入」
- 「受験日前 6 ヶ月以内に撮影したもの」
- 「デジタル写真は写真専用紙に印刷」
Why this spec matters
The Hazardous Materials Engineer (危険物取扱者, Kikenbutsu Toriatsukaisha) qualification is required for handling fuel, chemicals, and other materials regulated by the Fire Service Act — gas stations, chemical plants, tanker trucks, and similar workplaces. Roughly 500,000 candidates per year take Class A, Class B 1-6, or Class C combined, making it one of Japan's largest national exams. The admission-ticket photo is set by the Hazardous Materials Engineer Examination Center (delegated under Fire Service Act Art. 13-5) as a single nationwide spec — there are no prefectural or per-class variations. The spec is detailed: 4.5cm × 3.5cm, taken within 6 months of the exam date, plain-background upper-body portrait or passport-spec, printed on dedicated photo paper, with name / age / photo date written on the back, and glued (not taped) to the admission ticket. Failure to meet any of these blocks you from sitting the exam. A key difference from fully digital exams: even online (e-Gov) applications require printing the ticket and physically affixing a real photo — there is no direct photo-file upload.
How to create it for ¥200

- 1
Take the photo on your smartphone
Stand against a plain wall in a bright room. Face the camera directly — hat off (except for religious or medical reasons), no mask, no sunglasses, natural expression, eyes on the lens. Clear-lens glasses are okay but watch for reflections. - 2
AI removes background and resizes to 45×35mm
Upload the photo. AI removes the background, detects your face, and auto-crops to the Hazardous Materials Engineer Examination Center spec (4.5cm × 3.5cm, upper-body portrait or passport spec). - 3
Print on photo paper at a convenience store, write on the back, glue to ticket
After payment, a QR code and 8-digit user number arrive by email. Print on photo paper at 7-Eleven, FamilyMart, Lawson, Ministop, or Poplar nationwide (L-size from ¥30). Write name, age, and photo date on the back, then glue (do not tape) to the admission ticket.
