The Okuaizu Digital Archive (Okuaizu DA) is a regional archive established by seven towns and villages in western Fukushima Prefecture, collaborating with local governments. This paper explores how the digital archive system can be used for citizen-participatory activities, focusing on a workshop designed to organize and preserve folk tools using the Okuaizu DA. This practical approach helped to clarify the basic procedures and challenges of utilizing a digital archive for community involvement in cultural preservation.
