These certificates officially prove your skills and can open doors in companies, selection processes, promotions, and even work visas.

Why invest in Japanese certifications?
In an increasingly globalized world, multinational companies and academic institutions require formal proof of language proficiency. With Japanese, it is no different. Having a certification can be the decisive factor in securing a position or even negotiating a better salary.
Moreover, some work or residence visas in Japan require proof of language level. In business contexts, mastering Japanese at an advanced level can increase salaries by up to 30% to 50%, especially in sectors such as IT, translation, customer service, and international trade.
1. JLPT (Japanese-Language Proficiency Test)
The JLPT is the most well-known and globally accepted certification. Organized by the Japan Foundation, the exam is administered twice a year in dozens of countries and measures proficiency in reading and listening comprehension.
Levels and Professional Impact
The JLPT is divided into five levels:
- N5 and N4: Basic — shows that you understand simple sentences.
- N3: Intermediate — allows for broader communication.
- N2: Advanced — required by many companies and educational institutions.
- N1: Fluent — opens doors to high-level positions and academic careers.
N2 and N1 are the most valued certificates in the market. A professional with N2 can work in bilingual customer service, technical support, simple translation, and earn salaries between ¥250,000 and ¥400,000 monthly. With N1, it is possible to work as a technical translator, project manager, or in administrative positions, with earnings exceeding ¥600,000 monthly.
How to Prepare
The JLPT does not require speaking or writing skills. Therefore, study should focus on grammar, reading, vocabulary, and listening. There are free practice tests, books like “Nihongo Sou Matome,” and online platforms specifically for the exam.
2. J.TEST – Test of Practical Japanese
Less known outside Japan, the J.TEST is widely accepted by Japanese companies. Unlike the JLPT, it focuses on the practical application of the language in corporate daily life, including listening, reading, and vocabulary.
Advantages of J.TEST
- Applies to real-world contexts: emails, meetings, reports.
- Includes professional vocabulary and expressions from everyday business.
- Accepted by Japanese companies during hiring.
The test is divided into levels from A to F. To secure positions with good salaries, it is recommended to achieve level A or B, equivalent to JLPT N2/N1.
Companies that use J.TEST as a hiring criterion generally offer more competitive salaries, bonuses for language performance, and faster growth opportunities.
3. BJT – Business Japanese Proficiency Test
Targeted at those who intend to work with Japanese for business, the BJT is an excellent option for professionals in areas such as foreign trade, marketing, international relations, and management.
Distinctive Features of BJT
- Evaluates real communication in a corporate environment.
- Uses videos, emails, graphs, and authentic business situations.
- Scoring scale of 0 to 800, with above 600 considered excellent.
Companies that work with foreign clients or wish to expand into international markets highly value candidates with BJT. A good performance can mean not only higher salaries, but also promotions and bonuses for qualifications.
The BJT is administered by the Japan Kanji Aptitude Testing Foundation and can be taken online, making it easier for foreigners outside Japan to access.
4. Kanken – Kanji Aptitude Test (漢字検定)
Although not directly related to overall proficiency, the Kanken measures knowledge of kanji, the ideograms used in the Japanese language. For those working with writing, technical translation, literature, or education, this certification is a powerful differential.
High levels of Kanken (1 to 2) are rare even among natives, and mastering this content demonstrates a level of linguistic excellence. Specialized translators in academic or legal texts who possess the Kanken can charge higher rates per page.
Additional Certifications Worth Considering
Some specific sectors may require or value other complementary certifications in Japanese, such as:
- Japanese Proficiency Test for Nursing and Elderly Care – used for the immigration of healthcare professionals.
- Internal company certificates – large Japanese companies train and certify employees with corporate Japanese courses.
- Technical courses with language certification – culinary, fashion, or technology schools in Japan sometimes include language tests in their curriculum.
Conclusion
Investing in Japanese certifications is one of the most effective ways to increase salary, achieve promotions and secure a place in competitive markets.
If your goal is to work with the language — whether in person in Japan or remotely — certifying your level of proficiency is more than a differential: it is an increasingly common requirement.
Choose the certification that best fits your profile and area of expertise, and start preparing now. Investing in your level of Japanese can yield returns far beyond linguistic recognition — it can be the key to boosting your career.
