"Shogi Guide" (Shōgi Shinan), Tenpō 14 (1843), Edo Period manuscript copy - Hand-copied on the 25th day of the 8th month of Tenpō 14 (1843), with the closing inscription stating that it was copied by Watanabe Usaburō. This is a late Edo-period manuscript of practical shogi instruction, notable for preserving both a precise date and the name of the copyist. Compact in format and likely intended for study or instruction, it offers a valuable glimpse into the circulation of shogi knowledge in nineteenth-century Japan. ????????
