1. JLPT（日本語能力試験） N1/N2
The Japanese Language Proficiency Test (JLPT) is the most widely recognized certification. N1/N2 levels are often used as hiring/promotion criteria in Japanese firms. N1 requires understanding newspapers and business documents, ideal for managerial roles. N2 proves basic workplace communication skills.
2. BJT（ビジネス日本語能力テスト）
More practical than JLPT, testing real-world skills like email writing and meeting communication. Uses a scoring system (max 480); J1 (600+) certifies “business-ready” proficiency. Highly valued by global companies’ Japan offices, especially for client-facing roles.
3. JETRO認定 貿易日本語
The only official certification specialized in import/export operations. Covers L/Cs, commercial invoices, and trade practices. Essential for international divisions of trading companies/manufacturers, especially for sales and logistics roles. JETRO’s official materials provide practical simulations.
