Abstract
Japanese gardens, mainly built on natural materials, have special needs for particular kind of maintenance and care, as their landscape is very susceptible to both natural and human impact. In Japan, strenuous efforts have been made and resources have been allocated for the state-designated gardens of cultural properties. This study aims to investigate the actual changes of landscape of Katsura Imperial Villa garden from the Meiji era until today, and analyze techniques and philosophy on its daily maintenance and recovery from natural disaster like typhoon damage. The study relied on interviews and materials including photograph records and the restoration investigation design material.
