About Nihongo Challenge

Nihongo Challenge is a free study bank for people preparing for the JLPT N5, N4, N3 and N2. Our aim is to keep vocabulary, grammar, reading and listening practice in one organised place.

AI-written content

The grammar explanations, reading passages, questions and answer explanations on this site are written by AI. They are checked with automated tools and were reviewed by a second AI (ChatGPT), but they have not been reviewed by a native Japanese speaker and may contain mistakes. Please use official materials as your main reference and tell us if you find an error.

Vocabulary

The vocabulary lists are based on publicly available word lists for each level. They are not official JLPT lists; no official list is published. The list was digitised with automatic text recognition, then corrected and cross-checked against the JMdict dictionary, so some errors may remain. Part-of-speech information comes from JMdict.

This site uses the JMdict dictionary file, which is the property of the Electronic Dictionary Research and Development Group (EDRDG) and used in conformance with the group's licence (Creative Commons Attribution-ShareAlike 4.0).

Scores

Practice results are not official JLPT scores. JLPT scores are scaled, and any readiness indicator here is only an unofficial estimate.

Independence

This is an independent study aid and is not affiliated with the organizers of the JLPT.
