Nichi Japanese Dictionary

A free Japanese-English dictionary with pitch accent patterns, example sentences, and natural AI voices — all working offline.

Most Japanese dictionaries skip pitch accent entirely and don't allow linking to other words. Nichi shows it right in the entry, and allows you to click on every single word in example sentences to view more detail.

SEARCH YOUR WAY
Search in English, Japanese, or romaji. Results are ranked by word frequency so common words surface first. The full dictionary works offline with no account required.

PITCH ACCENT
See pitch accent patterns displayed directly on dictionary entries. Pitch accent changes word meaning in Japanese — Nichi helps you get it right from the beginning.
