Tsuko Ichiran

• Compiled: 1853

Tsûkô ichiran is a compilation of documents related to the foreign relations of the Tokugawa shogunate. Compiled in 1853 by Hayashi Fukusai and others, it spans the period from 1566 to 1825. Descriptions of Japan's relations are organized by country, and chronologically within that, across 350 volumes.

The text was reprinted in moveable type and published in eight volumes, from 1912-1913, the 23 volume appendix on coastal defenses, Tsûkô ichiran zokushû, being published as well.
