concrete constructions were also demolished. Again, the contractor used a hammer and chisel to dismantle the materials by hand to remove reinforcing bars in the concrete without damaging them.In this way, as time progresses, it is no longer just the demolition of wooden structures. Therefore, the conventional demolition contractor demolishes the wooden building, and the demolition of reinforced concrete construction is done by the contractor “Yamaya”, who specializes in stone cutting. The two traders were co-dependent as they relied on each other for work contracts. Although the division of labor was carried out in this way, old materials were no longer in demand. Around 1963, due to the mechanization of demolition, there was a decline in craftsmanship. The number of contractors today who can carry out demolition without damaging materials has decreased as there is a low demand to sell old materials.The photograph, Fig. 4 original drawings by Asahi shimbun.
