Outline of Final Research Achievements

The objectives of this study were (1) building long tree-ring chronologies in Japan, and (2) their applications in the science of cultural properties. A network of tree-ring chronologies was developed for the last two millennia. The correlation analysis demonstrated that the network is classified into four regional sub-networks, suggesting that dendrochronological provenancing of cultural properties are possible. The tree-ring network was successfully used for wide-area reconstructions of the past climate for East Asia. Novel techniques were developed using computer tomography and magnetic resonance imaging, which enabled non-destructive acquisition of high-resolution tree-ring images for dating cultural properties.
