App Description

Nihongo is an offline Japanese dictionary, flashcard app, and reading assistant, designed to make the best use of the time you dedicate to studying Japanese.

Our dictionary is made to find what you're looking for fast, with the words Japanese speakers actually use at the top of every search result, and every word marked as "common", "uncommon", or "rare".

"Clippings", our reading assistant, is what makes Nihongo stand apart from other dictionaries. Paste in Japanese text from a website, email, an eBook, or anywhere else, and we'll add furigana or romaji to every word. We also enable you to tap on any word to see its definition. This will truly change the way you read Japanese. And now, you can get the same experience right in Safari using our Safari extension.

Personal experience (as well as a good deal of research in second-language acquisition) has shown us that the words that you're most likely to remember are the words that you're encountering naturally. To this end Nihongo automatically draws from your search history and clippings to compile flashcard decks filled with words for which you already have context. This makes it easy to study both the words you looked up during Japanese class, and those that appear in your favorite song or videogame. And by adding notes to the back of flashcards you can further connect each vocabulary word to your personal contextual understanding.

Kanji flashcards prompt you to draw the missing kanji from the words you're studying, creating stronger connections between the characters and their real-world use. Built-in kanji decks give you 2 or 3 key words to study for each kanji.

This app is only possible because of the JMDict (edrdg.org) and Tatoeba (tatoeba.org) projects. I highly encourage you to support these incredible projects that make apps like Nihongo possible!
