The new Heibonsha’s World Encyclopedia, completely revised for the first time in 20 years in September 2007, features about 90,000 entry words and 420,000 index terms. The encyclopedia has been continually revised since then. The contents from the most recent 6th printing will be used for the JapanKnowledge edition.

The World Encyclopedia covers all areas of knowledge with well-balanced information. It is suitable for a variety of uses, from teaching schoolchildren how to research subjects to writing graduation thesis to everyday business use. The content of each entry is so exhaustive that the volume of some important entries is equivalent to a stand-alone book.

Shuichi Kato serves as the chief editor of a team of over 7,000 contributors. All entries carry the byline of their authors, indicating the encyclopedia’s trustworthiness bestowed by authorities in their respective fields.

With JapanKnowledge’s Advanced Search, the user can search index terms and subject filters. Furthermore, hyperlinks in the contents to The Complete Japanese Encyclopedia (Encyclopedia Nipponica) enable the user to get even more detailed knowledge.

※Some illustrations in the print edition are not included in the JapaneseKnowledge edition. Also not included are the “Japan Atlas,” “World Map Handbook” and “Encyclopedia Compendium.”
