The Japanese-Language Proficiency Test (日本語能力試験, Nihongo Nōryoku Shiken), or JLPT, is a standardized criterion-referenced test to evaluate and certify Japanese language proficiency for non-native speakers, covering language knowledge, reading ability, and listening ability.^[1] The test is held twice a year in Japan and selected countries (on the first Sunday of July and December), and once a year in other regions (either on the first Sunday of December or July depending on region).^[2] The JLPT is conducted by the Japan Foundation for tests overseas (with cooperation of local host institutions), and Japan Educational Exchanges and Services for tests in Japan.^[3]

The JLPT consists of five independent levels of certification, with 5 the lowest and 1 the highest.^[4] Until 2009, the test had four levels of certification.^[5] JLPT certificates do not expire or become invalid over time.^[6]

The JLPT was first held in 1984 in response to the growing demand for standardized Japanese language certification.^[7] Initially, 7,000 people took the test.^[8] Until 2003, the JLPT was one of the requirements for foreigners entering Japanese universities. Since 2003, the Examination for Japanese University Admission for International Students (EJU) is used by most universities for this purpose;^[9] unlike the JLPT, which is solely a multiple-choice exam, the EJU contains sections which require the examinee to write in Japanese.

JLPT certification can be used for many official purposes in Japan. For example, JLPT N1 or N2 certification can help foreign nationals receive preferential immigration treatment in some circumstances.^[10] Similarly, those who have passed either N1 or N2 (regardless of citizenship) are exempt from the Japanese language section of the middle school equivalency examination, which is required to enter a Japanese high school if the applicant did not graduate from a Japanese middle school,^[11] and N1 certification is sometimes accepted as an alternative to the Examination for Japanese University Admission for foreign students who wish to study at Japanese universities.

JLPT certification can also be required as a component of licensing in Japan. N1 certification is a prerequisite for foreign medical professionals who wish to take examinations to be licensed in Japan, and for certain foreign nationals who wish to attend nursing school in Japan.^[12] Further, under Japan's Economic partnership agreement with Indonesia, the Philippines, and Vietnam, a JLPT certificate is required for Indonesian, Filipino, and Vietnamese nurse or caregiver candidates who visit Japan.

Although the Japan Foundation does not provide an official table of comparison between the JLPT and other language proficiency exams, Japanese language textbooks^[13] and language courses at the university level tend to use the table on the right to compare JLPT results to the Common European Framework of Reference for Languages (CEFR) scale.^[14][15] Beginning in July 2025, JLPT score reports will include an official indication of corresponding CEFR levels.^[16]

In Japan, the JLPT is administered by the Ministry of Education, Culture, Sports, Science, and Technology (MEXT) through the Japan Educational Exchanges and Services (JEES).^[18] Overseas, the Japan Foundation co-proctors test administration with local cultural exchange and/or educational institutions, or with committees specially established for this purpose.^[19][20]

The revised test pattern was implemented in 2010. The test consists of five levels, with N1 the highest level and N5 the lowest. According to the exam, N1 represents "the ability to understand Japanese used in a variety of circumstances", N2 represents "the ability to understand Japanese used in everyday situations, and in a variety of circumstances to a certain degree", N3 represents "the ability to understand Japanese used in everyday situations to a certain degree", N4 represents "the ability to understand basic Japanese", and N5 represents "the ability to understand some basic Japanese".^[21] No Test Content Specification is published as it is discouraged to study from kanji and vocabulary lists.^[22]

The application period is usually around early March until late April for July's examination and around early August until late September for December's exam.

Results for the December test are announced the following February for examinees in Japan, and March for overseas candidates. Test results are sent to the examinees through the testing organization or center to which they applied.^[27] From 2012, with online registration, results are available online before they are mailed out (late August for the July test). All examinees receive a report indicating their scores by section. Those who pass also receive a Certificate of Proficiency.

As of 2004, when there were 302,198 total test takers, the JLPT was offered annually in 40 countries including Japan.^[28] Since 2009, two exams have been held each year in East Asia, and the yearly number of test takers had risen to 1,168,535 by 2019.^[29] As of 2021, the regions with the most test takers were Japan, Taiwan, China, South Korea, India, Vietnam, Brazil, Indonesia, Bangladesh, and Myanmar.^[30]

Until 2009, the test had four levels.^[5] JLPT certificates do not expire,^[6] so results from the previous format remain valid.

All instructions on the test were written in Japanese, although their difficulty is adjusted to remain appropriate to each test level.^[61] The subject matter covered at each level of the examination was based upon the Test Content Specification (出題基準, Shutsudai kijun), first published in 1994 and revised in 2004. This specification served as a reference for examiners to compile test questions, rather than as a study guide for candidates. It consisted of kanji lists, expression lists, vocabulary lists, and grammar lists for all four JLPT levels. However, about 20% of the kanji, vocabulary, and grammar in any one exam may have been drawn from outside the prescribed lists at the discretion of exam compilers.^[62]
