The artifacts recovered from the Walnut Grove are a significant addition to the research of the late nineteenth- and early twentieth-century Asian material culture. Of particular significance is the large collection of recovered Japanese ceramics. Deposited en masse following a devastating fire in 1915, they represent the table wares used by Walnut Grove's Japanese residents from ca. 1896 to 1915. Primarily products of the Meiji Period's technological revolution, these inexpensive porcelains have been largely overlooked in studies of Japanese pottery.
