Generally, several surveys, such as building structure, land subsidence
and material condition, are conducted to identify the original

planned in such a way as to use the original materials and techniques
to the extent possible, but also to address how the buildings were
to be utilized in the future. In particular, the principles of
this work were as follows; 1) The buildings were restored to preserve
their cultural value. 2) Sufficient structural reinforcement was
added to make the buildings more durable, and some problematic
parts were replaced for better upkeep. 3) Some parts of the site
and the buildings were modified for improved utilization.
