In relating the story of his life on the island of Deshima and in the port of Yokohama during the late 1850s, Dutch merchant C. T. Assendelft de Coningh provides both an unprecedented eyewitness account of daily life in the Japanese treaty ports and a unique perspective on the economic, military, and political forces the Western imperial powers brought to bear on newly opened Japan.

A general Introduction provides essential historical and cultural background as well as a brief biography of De Coningh; substantial footnotes explain those terms, names, and cultural references that may be unfamiliar to modern readers. Thirteen illustrations are included, as are a chronology of events, a bibliography, and an index.
