[Servers Using EDICT/JMdict]   [Other Free Servers]   [Commercial Servers]   [Dictionary Files]   [Link Collections]   [Unclassified]

Servers using EDICT, JMdict, etc.

These servers use files from the EDICT/JMdict, KANJIDIC, etc. projects, plus others in the same format.

  • WWWJDIC. Has many dictionary files: General (EDICT), Kanji, General (EDICT), Kanji, Computing/Telecoms, Place/Person names, Life Sciences, Law, Finance/Marketing, Miscellaneous, Engineering/Science, Buddhism, German, Russian, French, Spanish, Hungarian, plus text glossing, verb tables, kanji stroke-order diagrams, example sentences, etc. etc. Total lexicon size about 800,000 entries. Several mirror servers around the world. JE EJ (German, Spanish, French, Hungarian, Swedish and some Russian too.)
  • Jeffrey's Japanese<->English Dictionary Server. Developed by Jeffrey Friedl, now maintained by William Maton. Has most of the files used by WWWJDIC and has other options such as romanized output and a lookup technique that allows for common misspellings. The master site is now in Canada, and there are mirrors in the USA and Sweden. JE EJ
  • JEDI. (Japanese-English Dictionary Interface) at Kyoto Notre Dame University. Also has an option for romanized output. (This popular server has now closed down.) JE EJ
  • DIKU A very simple dictionary server written by a former JEDI user. Has romaji output as well as kana. JE EJ
  • jTango Another straightforward server. Has extras like stroke-order diagrams for kanji. JE EJ
  • Grzegorz Bober's Tangorin dictionary server. Uses JMdict, ENAMDICT, etc. as well as the Tanaka Corpus. Allows for building word-lists, search history, etc. JE EJ
  • Denshi Jisho is an attractive site with many features. The Ajax-style multi-radical lookup is impressive. JE EJ
  • Pacific Software Publishing's Bi-Directional English Japanese Dictionary (uses a very old copy of EDICT.) JE EJ <!-- #h JE --><!-- #h EJ -->
  • FOKS (Forgiving Online Kanji Search) is an online dictionary (EDICT, etc.) which compensates for spelling errors, incorrect guesses of a kanji's reading, etc. Well worth exploring. JE EJ
  • the Tokyoahead site has a form of kanji dictionary which allows kanji selection and generates a wordlist. JE
  • the FreeDict EJ/JE dictionary. (I do not like this one. It uses a romanized version of EDICT, and presents a small number of entries in a misleading order.) JE EJ
  • AnimeLab. Uses the EDICT, ENAMDICT, etc. files, and has some interesting search options. JE EJ
  • NihongoResources. Uses EDICT and KANJIDIC. Has some useful wildcard search facilities. JE EJ
  • The Japanese dictionary at Online-Dictionary.biz covers 7 modern languages including as Japanese. Uses a Javascript romaji-kana system (no native Japanese input yet), and also uses the WaDokuJT file to produce German glosses. Has the same examples as WWWJDIC. JE EJ
  • Spencer's EDICT and KANJIDIC server. JE EJ
  • The Heartful server at Toyohashi University of Technology does a crude EJ lookup. EJ
  • The JapanOD server, which has a very novel interface. Has mobile phone options, etc. JE EJ
  • NihongoDict, which does a quite basic service using romaji. JE EJ

Other Servers (Free)


  • Thesaurus. Very extensive coverage, including synonyms, related words, etc. JJ

General Dictionaries (Japanese-English)

  • GOO. One of the best servers available is that at the Goo site (Goo is an information project sponsored by NTT in Japan.) This server has four Sanseido dictionaries available: the big Daijirin kokugo (i.e. Japanese-Japanese) dictionary, the Exceed EJ and JE dictionaries, and the Daily Shingo (new word) dictionary. The server has all the instructions, etc. in Japanese. A very useful resource indeed. JJ JE EJ
  • Asahi. Almost identical service to the Goo server (above). (The server appears to be on a Sanseido system.) JJ JE EJ
  • Yahoo. Another good collection of online dictionaries (uses Shogakkan). JJ JE EJ
  • LiveDoor. A similar set of Shogakkan dictionaries. JJ JE EJ
  • Excite. Another service using commercial dictionaries. This also uses the Daijirin kokugo, and the Kenkyusha Chuujiten JE and EJ. JJ JE EJ
  • Eijiro. (aka ALC) Another useful resource with a vast list of Japanese words and phrases with their English translations. It can also be bought as a book and CDROM. (Some care should be taken with this resource, as the English translations can be quite quirky, and at times plain wrong.) JE EJ
  • Glova. A very large word collection, from a translation company. JE EJ
  • Kokken's jiWORDS (Japanese info on Words) server uses the Sanseido dictionery, and does all the Japanese text with bitmaps (quite unnecessarily in my humble opinion.) JJ JE EJ
  • Babylon. Among its many dictionaries, Babylon has an online E-J lookup service and a rather crude index system for J-E. Dictionary size is reasonable. EJ
  • jeKai Search. The jeKai project (see below) has a good search engine, but since it has limited material available, it may be better to use their index. JE
  • Words/Examples. A fairly basic JE dictionary, but with usage examples drawn from parallel corpora. (The front page says it has over 300,000 words, but I suspect there are fewer actual headwords than that.) (Site currently not operating)
  • Unicode Characters. A fairly simple lookup of the big Unihan text file via the meaning of the kanji/hanzi or the Chinese, Japanese or Korean readings.

General Dictionaries (Japanese-Other Language)

Subject-specific Dictionaries

  • The RNN (Rapid News Network) page has a set of JE/EJ wordlists that are searchable. Topics covered include: business/economics, international affairs politics, technology, culture and sport and society.

  • Place names. The Yuujirou server using the Ministry of Posts and Telecommunications (MPT) database of locations and postal codes. You can paste in a complete address, and it will be parsed and the correct readings of the names returned. (The same database is the source of the j_places file used by WWWJDIC.) JJ
  • Science/Technology This server at NII has a large number of scientific, etc. terms, which can be searched together or by category. JE EJ
