The National Diet Library’s online database is a treasure trove of primary sources of Bakumatsu-Meiji Restoration history. This one, for example, has been useful in my research on the Shinsengumi:

Tamamushi Yoshishigé’s Kanbu Tsūki (官武通紀), a historical record of the three-year period from Bunkyū 2 to Ganji 1 (1862 – 64), was originally published in 1913 by Kokusho Kankōkai. Tamamushi was a samurai of Sendai Han.

Tamamushi’s book is another valuable primary source in my continuing research on the Shinsengumi, particularly for my forthcoming Samurai Swordsmen: The Definitive History of the Shinsengumi (1863–1869). See the Shinsengumi Hub for additional essays and updates.

Recently I have been focusing on my forthcoming Samurai Swordsmen: The Definitive History of the Shinsengumi (1863–1869), scheduled for publication in fall 2026 with Helion. I also provide consulting on Bakumatsu–Meiji Restoration history and culture to authors, editors, publishers, documentarians, producers, screenwriters, translators, and other professionals who need expert guidance on the era.
