The Complete Japanese Encyclopedia (Encyclopedia Nipponica) is an enormous collection of information, including approximately 140,000 entries and 500,000 index words, all of which can be accessed on JapanKnowledge.
The JapanKnowledge edition of the Complete Japanese Encyclopedia is one of very few full-scale encyclopedias that is regularly updated and revised, something that was impossible to do with paper-media books or CD-ROMs and DVD-ROMs.
The JapanKnowledge edition is complete with a refined search function for individual searches, in which hierarchies can be traced down for each field such as natural science, medical science, economics and literature. The Encyclopedia also includes links to related entries as well as plentiful graphic materials, through which the encyclopedic world can be enjoyed to your heart’s content.
