Encyclopedia Nipponica

Encyclopedia Nipponica (日本大百科全書, Nihon Dai Hyakka Zensho^?, lit. The Japan Comprehensive Encyclopedia) was published in 1984 from Shogakukan. The first edition of Encyclopedia Nipponica included 25 volumes and was completed in 1989. Encyclopedia Nipponica was intended to further describe Japan and the Japanese in depth. After 10 years of preparation, over 130,000 entries and 500,000 indexes were organized in alphabetical order in more than 23,000 pages. The most recent version, 1994, has 26 volumes, including the separate volumes of indexes and an auxiliary. However, Encyclopedia Nipponica is currently out of print.

When it was founded in 1922, Shogakukan specialized in study books and magazines for elementary school students. According to its websites, 日本百科大事典 (Nihon hyakka daijiten) published in 1962 was the first encyclopedia from Shogakukan.

Shogakukan's Encyclopedia Nipponica has been one of the major Japanese encyclopedias. The other major encyclopedia, Heibonsha World Encyclopedia (世界大百科事典, Sekai daihyakka jiten), was published from Heibonsha. Since the foundation in 1914, Heibonsha has put emphasis on encyclopedias. Currently, World Encyclopedia holds three editions: World Encyclopedia, World Encyclopedia on DVD, and the online edition called Netto de hyakka.
