Completed

Translating, Digitizing, and Publicizing Medieval Japanese Documents

Research Term August 2025 – March 2026

Principal Investigator Toshiaki Yanagihara (Professor, Graduate School of Arts & Letters)

Overview

In the past, both the primary and collaborative researchers for this project taught a course together for the English translation of the Documents of Hōzawa held at the Department of Japanese History in the Faculty of Arts of Letters, and supervised the compilation of a full translation of the materials. Based on this previous work, this project will accomplish the following goals.

a. the construction of a digital database on ToUDA hosting manuscript images, transcriptions, and English translations, as well as explanations, of the Hōzawa documents
b. the publication of these translations and transcriptions in the Kokushi danwakai journal of the Department of Japanese History
c. the creation of a week-long exhibition at Tohoku University Library on the Hōzawa documents, to be held between September 29 and October 5, 2025

While there have been several English translations of Japanese medieval documents, very few translations of full document collections exist, making the digital and physical publicization of these documents in Japanese and English a worthy contribution to research in Japanese studies both inside and outside of Japan.

The article “The Documents of Hōzawa” has been published in Kokushi Danwakai Zasshi No. 66 as an outcome of the collaborative research project “Translating, Digitizing, and Publicizing Medieval Japanese Documents,” led by Professor Toshiaki Yanagihara and Assistant Professor John D’Amico. This publication provides English translations, detailed annotations, and commentaries for 16 medieval documents from the Hōzawa Documents collection held by the Department of Japanese History. The translations were produced by students in graduate seminars and supervised by Assistant Professor D’Amico. It is expected to serve as a valuable resource and textbook for Japanese Studies and pre-modern Japanese history research in English.
