Kamakura Ibun

Kamakura Ibun (Collection of Historical Materials of the Kamakura Period) comprises 42 volumes with 4 ones of supplementary materials published by Takeuchi Rizo (1907-1997, former head of the Historiographical Institute, The University of Tokyo; Professor Emeritus of the University of Tokyo; and Honorary Doctor of Waseda University) over a period of 24 years from 1971(Showa 46). Thus, it is a complete collection of all roughly 36,000 antique texts from the Kamakura period.

In 2006, the Historiographical Institute, The University of Tokyo produced and published the Full Text Database of Kamakura Ibun based on the above-mentioned Kamakura Ibun, and this led to the publication of the “CD-ROM Version of Kamakura Ibun” by Tokyodo Shuppan Co., Ltd in 2008. The “Web Edition Kamakura Ibun” now being made available from JapanKnowledge contains not only all the volumes of Kamakura Ibun, but also a database that includes new research achievements, not contained in the CD-ROM version, such as the Kamakura Ibun Supplementary Materials Edition of the Toji Temple Documents (3 volumes) edited by the Kamakura Ibun Research Group, and the “Revised ‘Shirakawa Volume of the Toji Temple Documents’ included in the ‘Kamakura Ibun’” (Kamakura Ibun Research, issues 1 to 10, edited by the Kamakura Ibun Research Group) produced by the Medieval History Seminar of the Graduate School of Waseda University.

The most important feature of this web version is that a type-page of the book can be browsed on the same screen as a keyword search. Illustrations and genealogical charts are also displayed, this being impossible with the CD-ROM version. Furthermore, a link to the "Union Catalogue of Japanese Historical Documents Database" at the Historiographical Institute, The University of Tokyo, is also provided, enabling access to various types of information through the “Web Edition Kamakura Ibun,” making it a more convenient and accessible tool for conducting advanced interdisciplinary research.
