This research examines the transformation of reed beds in Omihachiman, a city on the eastern shore of Lake Biwa, in 1920-2005. In contrast with other areas around Lake Biwa, the study area of continues to be involved in reed-land management and the production of reed-derived goods; however, even in this area, reed production is in decline and local life styles continue to change such that conserving and managing reed beds has become complicated. Owing to this continuing legacy and the threats it faces, this area was designated as a cultural landscape in 2006 by the Agency of Cultural Affairs. This research focuses on land-use changes and the transformation of reed beds. This is accomplished mainly through an examination of topographical maps and historical records. Our results demonstrate a strong correlation between historical reed-production and the current distribution of reed beds. In addition, land reclamation, river construction projects have shaped today's reed landscape. Finally, movements to conserve reed beds as cultural properties and to preserve biodiversity have affected their distribution. The historical transformation of reed beds illustrates the importance of maintaining and regenerating the relationships between humans and reed beds when planning for cultural landscape conservation.
