Found a mistake in a word pair explanation? Have a suggestion for a new pair? We want to hear from you.

KotobaaNavi covers over 1,200 Japanese word pairs, and accuracy matters. Every explanation has been researched against multiple dictionaries and reference materials, but errors do slip through. If you spot an incorrect nuance, a wrong example sentence, or a misleading mnemonic, please let us know — we take all corrections seriously and fix them quickly.

We also welcome suggestions for new word pairs to add, especially confusing vocabulary that Japanese learners frequently mix up. If there's a pair you've struggled with that isn't yet on the site, send it our way.
