Sakura Japanese Dictionary (桜英和和英辞典) is an English–Japanese and Japanese–English dictionary built on EDICT, the long-running open Japanese–English dictionary project that began in 1991 and has become a standard reference online. Enfour has contributed to EDICT almost from the start.
For this app, Enfour optimised the EDICT data for its UniDict® dictionary engine, creating a search index of around half a million terms. You can look words up from English, Japanese, or kana and see results update instantly, which makes the app quick to use whether you are reading, studying, or travelling.
An optional kanji dictionary extends the app with detailed information on individual characters, including stroke-order animations and handwriting recognition. It is a good fit for English speakers learning Japanese who want a fast, comprehensive dictionary on their iPhone or iPad.
