Terms of use
Nihongo is a free project for Vietnamese learners of Japanese. A few things to be clear about before you use it:
Free, provided as-is
You use this site for free and there is no paid tier. In exchange, everything is provided as-is: we do not promise the site is always reachable, we do not promise your study data can never be lost, and any feature may change or stop at any time. Treat it as a study aid, not as your only copy of anything.
The content can be wrong
The vocabulary, kanji and grammar here come from open datasets, and some translations are machine-made and clearly marked as such. We do check them, but errors remain. Do not rely on this site alone for an exam or for translation work.
JLPT level lists are unofficial
The Japan Foundation has not published per-level content specifications since 2010, so the N5–N3 assignments here are community estimates. Details on the Licenses & credits page.
Content and licensing
The learning content derives from open projects (JMdict and KANJIDIC2, KanjiVG, Tatoeba, tanos.co.uk). If you reuse it, follow each source's license — see Licenses & credits.
Please do not abuse it
Do not generate unusual traffic, do not scrape in bulk, do not try to reach other people's accounts, and do not use the error-report form for spam. Accounts that do get deleted.
