Museum “Diaspora” Collections for Archaeological Research: Edo-Period Shogun Family’s Funerary Lanterns Outside Japan

ABSTRACT This paper advocates using museum collections for archaeological research by offering a new approach to generate questions on the sociocultural lives of ancient people. I define “diaspora” collections as historical and archaeological artifacts excavated in a homeland site but currently stored in museums that are outside the homeland country. Of particular importance in this approach is the identification of artifacts’ diagnostic traits, including material composition, morphology, and symbolic decoration, that are to be linked to the “original” data in their homeland. Diaspora collections-based research necessitates provenience studies, as well as direct observation of both the diaspora collection and its original data. It also takes advantage of the recent development of various digital and remote technologies. A case study to show this methodology comes from dedicatory lanterns currently stored outside Japan that were part of the shogun (Tokugawa) family’s graveyards in modern Tokyo during the 18th and 19th centuries a.d.
