Excavation of buried cultural properties

　The new city hall maintenance site is land that was reclaimed from the late Edo period to the Meiji era.
　After that, there was a record of the construction of modern buildings from an early age, so in March 2015 we conducted an exploration survey of buried cultural properties.
　As a result, it was confirmed that the buried cultural property was located, so it was designated as a buried cultural property storage area.
　At the buried cultural property storage area, it is necessary to conduct an excavation survey before construction work based on the Cultural Property Protection Law, and we are currently conducting a survey.
