Third-Class Electric Chief Engineer 電験三種 (Theory/Power/Machine/Law)
Free theory-preview practice set for the Third-Class Electric Chief Engineer (電験三種) examination in English. This qualification covers four written subject areas: Electrical Theory, Power Systems, Electrical Machinery and Applications, and Law, Safety and System Management. Because the Third-Class credential is assessed by written examinations only, this preview contains no practical-work items; all questions test underlying theory, calculation, and regulatory principles that apply to the written subjects. Questions below are original practice items based on stable electrical engineering principles and publicly documented regulatory scope; they are not official examination questions.
Second-Class Electric Chief Engineer 電験二種 (Primary + Secondary)
Free practice preview for the Second-Class Electric Chief Engineer (電験二種) covering both the primary (theory) and secondary (theory) examinations at a theory-preview level only. This qualification is administered in Japan, and the official examination center provides authoritative administration information; no official past questions are reproduced here. All 20 questions and 20 flashcards are original study items built on stable electrical engineering principles across Electrical Theory, Power Systems, Electrical Machinery and Applications, and Law Safety and System Management. This preview does not reproduce secure exam content and makes no claims about current item counts, pass marks, fees, or schedules.
First-Class Electric Chief Engineer 電験一種
Free practice preview for the First-Class Electric Chief Engineer (電験一種) examination. This is a theory-only preview: the qualification covers electrical theory, power systems, electrical machinery, and the laws, wiring, installation, measurement and safety topics applicable to the chief engineer role. Questions here are original practice items testing stable engineering principles and application, and are not official examination questions. Law-related items test general, well-established regulatory concepts only and do not state specific fees, deadlines, passing scores or item counts.
Type 1 Electrician 第一種電気工事士 (Written + Practical)
Original practice preview for the Type 1 Electrician (第一種電気工事士) written-examination scope, covering Electrical Theory and Circuits, Equipment Wiring and Diagrams, Installation Inspection and Measurement, and Regulations Safety and Practical Judgment. This module is a theory and decision-making preview only: the actual credential includes a practical skills assessment, and these original questions and flashcards do not replace required hands-on preparation, official study materials, or the practical work itself. All questions are original practice items based on stable electrical principles and are not official examination content.
Type 2 Electrician 第二種電気工事士 (Written + Practical)
Free preview module for the Second-Class Electrician (第二種電気工事士) written examination, covering basic electrical theory, wiring diagrams and equipment, installation inspection and measurement, and regulations/safety judgment. All items are original practice questions for theory review only. The written test does not replace hands-on preparation; the second-class credential additionally requires a separate practical skills test with wiring work, so learners must still complete practical training. Content follows publicly available official overview material from the Japan Vocational Ability Development Association testing center; no fees, dates, pass marks or secure exam content are reproduced.
1st Class Electrical Construction Management Engineer 一級電気工事施工管理技士
Free theory-preview practice set for the 1st Class Electrical Construction Management Engineer (一級電気工事施工管理技士) examination. This credential, governed by Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT), assesses planning, quality, safety, schedule control, construction methods, and applicable regulations for electrical construction work. This preview contains original practice questions and flashcards covering stable technical principles and applied calculations. It is a theory-only preview: it does not reproduce secure exam content, does not state official pass marks, item counts, fees, or dates, and does not claim these items are official questions. For this practical qualification, the real examination includes subject-specific practical assessment that cannot be simulated here; this resource prepares foundational knowledge only.
2nd Class Electrical Construction Management Engineer 二級電気工事施工管理技士
Free preview practice set for the 2nd Class Electrical Construction Management Engineer (二級電気工事施工管理技士) qualification. This preview covers theory-based subject knowledge only; the actual certification includes a subject examination and, for 2nd Class, practical/experience-based qualification routes that cannot be reproduced here. All questions are original practice items based on stable electrical construction principles: wiring methods, grounding, planning, quality control, scheduling, safety management, and related laws such as the Electricity Business Act and Construction Industry Act. Question counts, pass marks, fees, and secure exam content are not reproduced.
Energy Manager Exam エネルギー管理士 (電気分野)
Free original practice preview for the Energy Manager Exam (エネルギー管理士, electrical field) covering electrical energy fundamentals, equipment systems and efficiency, measurement and optimization, and energy law with applied calculations. This is a theory-only preview: the practical-stage content of the actual qualification is not reproduced, and all questions here are original study aids written from stable engineering principles, not official items. No fees, dates, pass marks, or secure exam content are included.
