Diaries, journals, sketches, correspondence, scrapbooks, research files, lecture notes, publications and other papers of Edward Sylvester Morse, one of the first Americans to live in Japan. These provide a wonderful insight into the culture and society of Meiji Japan. In addition to preserving the household records of a samurai family and many accounts of the tea ceremony, Morse made notes on subjects as diverse as shop signs, fireworks, hairpins, agricultural tools, artists' studios, music, games, printing, carpentry, the Ainu, gardens, household construction, art and architecture. Morse devoted much of his life to the task of documenting life in Japan before it was transformed by Western modernization. The records also cover his work at the Imperial University of Tokyo where he taught science and was Chair of Zoology. He was a crucial figure in the initial engagement between Japan and America and his papers are also important for relations between East Asia and America in the first decades of the twentieth century.
