Nihongo Daijiten

The Nihongo Daijiten (日本語大辞典^?, "Great dictionary of Japanese") (English title: The Great Japanese Dictionary) is a color-illustrated Japanese dictionary edited by Tadao Umesao and published by Kodansha in 1989 and 1995 (2nd edition).

The Nihongo daijiten was one of three Japanese dictionaries specifically published to compete with Iwanami's bestselling Kōjien (1955, 1969, 1983). The others were Sanseido's Daijirin (1988, 1995, 2006) and Shogakukan's Daijisen (1995, 1998). These four general-purpose kokugo jisho (国語辞書 "Japanese language dictionaries") are bulky reference works that weigh approximately 1 kilogram.

Along with the chief editor Umesao Tadao, other Nihongo daijiten editors included Kindaichi Haruhiko (金田一春彦, 1913–2004), Sakakura Atsuyoshi (阪倉篤義, 1917–1994), and Hinohara Shigeaki (日野原重明, 1911- ).

Kodansha's first Color-edition Nihongo daijiten (1989) included over 175,000 headword entries. This dictionary also incorporated encyclopedic content such as color pictures, proper names, allegedly "10,000" kanji entries (many with Japanese input method JIS X 0208 codes), and some 100,000 English translation glosses for modern Japanese words.

The 2nd edition (1995) expanded by almost 250 pages, giving 200,000 headwords, 120,000 English glosses, and 6500 color illustrations. The printed Nihongo daijiten version came with an electronic book CD-ROM containing some additional digital content (graphic data, sound files, etc.). In 2001, Sony licensed Kodansha's Nihongo daijiten and released a Japanese TVware version for PlayStation 2.
