52reliable structural analysis and reinforcementfollowing their respective approaches forpreservation.　Regarding modern architecture andmodern heritage properties, adaptive use afterrestoration is often actively sought after for useby the general public. Therefore, substantialseismic protection to insure safety is required.In such cases, seismic resistance of the structurewill need to be thoroughly clarified and on thepart of restoration of cultural properties, skillsfor surveys and analysis not undertaken beforein restoration have become requisites.　For reinforcement that was judged to benecessary, particularly in the walls of brickmasonry, stone masonry, or reinforced concretestructures, appropriate methods that wereminimum and effective were sought after. Thisconcern resulted in the development of notonly hidden reinforcement methods, but alsothose intentionally visible from the interioror exterior. They were derived from studieson the building’s aimed seismic resistanceminimizing intervention with the structureitself, as well as to meet growing concerns inappropriate design for visible reinforcement tobe added onto a structure. Here again, studiesin basic approaches founded in the principlesfor cultural properties protection, from thestage even before the emergence of technicaldifficulties, become necessary for deciding onproper treatment measures or details requiredfor introducing reinforcement.(5) Adaptive Use　As can be read from chart 1, modernarchitecture and modern heritage propertiesas compared to temples and shrine or folkhouses, the variety of construction categories inrestoration as well as those related to adaptiveuse, such as introduction of facilities or newconstruction of subsidiary buildings, appear asnew elements. They will be dealt with hereon.　In the early days, most of the restoredmodern works of architecture were usedas museums and rarely were new facilitiesintroduced10). In many cases, even in rooms formanagers who stay there the whole day, therewas no air conditioning. In the summertime,windows were kept open and electric fans wereused; in winter, small kerosene heaters wereall that was available. No additional lightingwas installed and they were reluctant to makeholes in the walls for electric wiring, so therewas neither television nor telephones. In somecases, no new toilet facilities were placed in thecultural property building itself. All that wasintroduced were fire prevention systems. Thus,restoration generally used to avoid any possibleintervention to the building, except for safetymeasures.　However, with a growing number ofbuildings that are being restored for adaptiveuse, things began to change. Installation ofair conditioners, of course, became available,as well as supplementary lighting, electricoutlets, water facilities, partial alterations towall partitions, slopes and elevators for barrierfreeaccess, and new construction of subsidiarybuildings.　What then became an emerging issue inadaptive use of historic buildings were thenegative effects it may have on the historicstructure. For example, whether or not thestructure can be harmed for installation ofwires and pipes or introduction of facilitiesbecame a problem. If this were to be permitted,then, where and how should they be placed?Their sizes and colors will also need to bestudied. Such changes will naturally need to
