49preserve the site’s facilities at the time when themine ceased operation, while at Sado Mines,when the mine closed temporarily. The allintend to preserve for the most part the statethey are in today.　At these places, interior spaces retain thecondition at the time the facilities stoppedoperation, together with the various tracesof people who worked there. Decisions tomaintain these properties in such statespossibly was derived from a viewpoint that thelayering of history which can be experiencedthrough the remaining “living” objects wouldbe effective for gaining wider social acceptance.　Particularly regarding modern heritageproperties with still only a small numberrestored, the significance of each propertyneeds to be clarified through research byacademicians and surveys by specialists, tohave preservation measures thoroughly studied,taking into account the various possibilities forfuture usage by the public that would enhancethe structures’ characteristics. A major taskwould be to seek ways to effectively organizethe stream of events to include each stage,starting from the processes of restoration tocitizen participation for utilizing the preservedstructures.(2) Restoration of the Structure Itself　As explained earlier in section 1, the differentwork categories required for restoration ofmodern architecture and modern heritageproperties are wide-ranging and include thetreatment of such structures as brick masonry,stone masonry, reinforced concrete, and steelframe as well as new materials, methods, andspecifications for interior and exterior finishes,often those that have never before been dealtwith. All of these elements that comprisea work of architecture become objects ofrestoration. Additionally, many of these wereindustrially manufactured. Can restoration ofsuch structures and new materials be handledwith skills and knowledge acquired throughrestoration of traditional architecture?　“Retaining the original material” is arestoration principle that has been followedas though it were an inviolable rule. Thebasic ideas will be explained, using a buildingmember of a wood-frame structure as anexample.　To “retain the original material” means toinherit to the future something conveying theoriginal truth, which cannot be recreated andcontains the following information.・ Lumber processing saw marks made byhand-held tools or machinery・Traces of surface finishing and their accuracy・ Unit of measurement employed inconstruction, dimensions, and standards・ Wood joining methods as well as traces ofwalls and fittings clarified from observationsof mortise holes and nail holes・ Where trees for construction were grown,processed, and how they were delivered tothe site・ Species, quality, and grade of the selectedmaterial・ Degree of industrialization as seen in the useof nails and hardware　Such information can be acquired directlyfrom this building member. We must not forgetthat there is important information confined inthis element, which is unknown to us today butcan be passed onto the future.　From this point of view, works ofarchitecture also play a role of conveying notonly academic knowledge clarified throughresearch in the fields of architectural history
