Homepage of the JapanKnowledge collection of the Shiryo Sanshu.
As part of our ongoing effort to strengthen access to premodern Japanese historical sources, we announced earlier this fall the addition of the complete digital transcription of Heian Ibun (平安遺文). Building on that momentum, we are pleased to now offer access to the first unit of Shiryō Sanshū, newly available through the JapanKnowledge platform.
This initial release includes documents and diaries dating from the Heian, Kamakura, and Nanboku-chō periods, offering valuable insight into Japan’s premodern past. The collection features writings by prominent historical figures, including Prince Shigeakira (4th son of Emperor Daigo, 重明親王), Emperor Hanazono (花園天皇), Fujiwara no Teika (藤原定家), and Nakahara Momori (中原師守), among others. These diaries and journals allow researchers to explore the daily lives, thoughts, and concerns of court nobles and members of the imperial family.
The Shiryō Sanshū is a highly respected compilation of ancient diaries and documents, published by Yagi Shoten (八木書店), a Tokyo-based publishing house, between 1968 and 2020. The series encompasses more than 260 documents spanning from the Heian period through the Edo period. Each volume has been meticulously digitized, presenting both the original script and modern Japanese transcriptions. This dual-format approach enables full-text searching using both historical and modern character forms.
