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 Japanese in depth and at large. 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.
