About Kanji Tango

Kanji Tango finds common dictionary vocabulary that can be written using only the kanji you select. Selections live in the URL, so bookmarks work without an account or cookie.

Vocabulary rule

A result must contain at least one kanji, and every kanji in its dictionary spelling must be selected. Kana and punctuation do not add requirements.

Data sources

• JMdict and KANJIDIC2, from the Electronic Dictionary Research and Development Group.
• JmdictFurigana for kanji-to-reading alignment.
• wordfreq for frequency estimates.
• kanji-data for unofficial modern JLPT estimates.
• Tatoeba Japanese-English example sentences, including material from the public-domain Tanaka Corpus. Tatoeba exports are available under CC BY 2.0 FR.

Candidates prefer sentences whose other kanji are already in the current selection. Tatoeba data can be obtained from its downloads page.

The current data build is wordfreq-3.1.1-tatoeba-2026-07-28. JLPT sections are third-party estimates: the modern JLPT does not publish official kanji lists.
