Japanese Electrician Vocabulary — Technical Terms for the Japanese Workplace
Bangladesh sends thousands of skilled workers to Japan every year, many in the construction and electrical engineering sectors. For electricians, electrical engineers, and construction workers, understanding Japanese technical vocabulary is essential — both for on-site safety and for qualifying through the Japan Technical Intern Training Program (TITP) and Specified Skilled Worker (SSW / 特定技能) visa schemes.
Why Technical Vocabulary Matters
On a Japanese construction site, instructions come in Japanese: 電源を切ってください (please cut the power), 配線を確認してください (please check the wiring), 感電に注意 (warning: electric shock hazard). Misunderstanding a safety instruction can be fatal. Even for office-based electrical engineers, reading circuit diagrams, specifications (仕様書, shiyōsho), and inspection reports requires Japanese technical literacy.
Key Technical Categories
- Basic electrical terms: 電気 (denki — electricity), 電圧 (den-atsu — voltage), 電流 (denryū — current/amperage), 電力 (denryoku — electric power/wattage), 抵抗 (teikō — resistance), 周波数 (shūhasū — frequency).
- Equipment: 変圧器 (hen-atsuki — transformer), 配電盤 (haiden-ban — distribution board), ブレーカー (burēkā — circuit breaker), コンセント (konsento — electrical outlet), スイッチ (suicchi — switch), 電線 (densen — electric wire/cable).
- Work actions: 配線する (haisen suru — to wire), 接続する (setsuzoku suru — to connect), 絶縁する (zetsuen suru — to insulate), 点検する (tenken suru — to inspect/check), 修理する (shūri suru — to repair).
- Safety: 感電 (kanden — electric shock), 漏電 (rōden — electrical leakage), 過負荷 (kafuka — overload), 短絡 (tanraku — short circuit), 接地 (setchi — grounding/earthing), 安全装置 (anzen sōchi — safety device).
Japan's Electrician Qualification System
Japan has a national electrician certification system. The 第二種電気工事士 (Dai-ni-shu Denki Kōjishi) — Second Class Electrician — is the entry-level qualification for residential electrical work. The 第一種電気工事士 covers larger installations. Foreign workers in the Specified Skilled Worker (電気・電子情報関連産業) field must pass Japanese language and technical skills evaluations. This module is designed to help Bangladeshi electrical workers prepare for those assessments.
This module contains 599 electrical engineering vocabulary items with kanji, readings, meanings in English and Bengali, and quiz practice — covering all major categories needed for technical work and qualification exams in Japan.
