Mazii: Japanese Dictionary

You're staring at a kanji you can't read. A word goes by in a Tokyo meeting before you catch it. Your JLPT is a week away and you're jumping between five apps to get through a single page.

Mazii is a Japanese dictionary — built to put the right answer in your hand the moment you need it. Start there, and everything else is right where you'd expect it.

170,000 WORDS, DEFINED IN FULL

Look something up and you get more than a translation: native pronunciation, meanings, usage notes, and example sentences drawn from how Japanese is actually written and spoken. The dictionary holds 170,000+ Japanese–English and 140,000+ English–Japanese entries, and every one of 12,000+ kanji comes with its readings, meanings, and stroke order.

MORE THAN JAPANESE–ENGLISH

Your phone is in English, but you might think in another language. Mazii is also a Japanese dictionary and translator for Vietnamese, Chinese, Korean, Indonesian, French, and Filipino — so you can look a word up in the language you know best.

LOOK UP GRAMMAR THE WAY YOU LOOK UP A WORD

Search any grammar point from N5 to N1 and get a straight explanation with example sentences that show it in use — the pattern you couldn't parse in your textbook, broken down in seconds.

FOUR WAYS TO FIND ANY WORD

Typing Japanese is the slow part, so Mazii lets you skip it. The two learners reach for most:

- Handwriting: draw a kanji stroke by stroke and find it, even when you have no idea how it reads.

- Camera: point your phone at a sign, a menu, a label, or a page of a textbook and read it on the spot.

And when typing or speaking is faster:

- Voice: say the word out loud.

- Text: enter kanji, hiragana, katakana, or romaji.

AI TRANSLATE, IN CONTEXT

Give Mazii a full sentence or a whole conversation and it translates the meaning in context, not word by word — so what comes back reads the way a person would actually say it. Wondering why a word is used that way? Ask the AI and it explains in plain English.

SPEAK JAPANESE AND GET CORRECTED

Talk to Mazii in Japanese. It listens to your pronunciation and points out what to work on, corrects your grammar as you write, and keeps the conversation going, so you practice speaking, not just reading.

TURN EVERY LOOKUP INTO A FLASHCARD

Save any word you search into your own notebook and review it by listening, speaking, writing, and matching. The words you look up today become the ones you keep, and your notebook syncs across every device you use.

BUILT FOR JLPT

Sit N5 to N1 mock tests written to match the actual exam — vocabulary, grammar, reading, and listening. Finish one and you see exactly which sections are shaky, so you know what to look up before test day.

NEWS, AND A COMMUNITY THAT ANSWERS

Read Japanese news updated every day and tap any word to get its meaning without leaving the page. When you're stuck, over a million learners are in the community, answering questions and trading study tips.
