analysis. This report is the final result of these procedures,including three papers by specialists (Chapters 2, 3, and 4),along with a record of a seminar held at our institute (Chapter5), a list of case studies of preservation and restoration ofbrick structures, and an appendix.First, a discourse from a specialist, to deal with the issueof“re-laying and replacement of bricks”from the viewpointof it being an aspect of the basic significance of a culturalproperty, was given by Dr. Naoji Hasegawa by the title of“Techniques and Significance of Brick Masonry Structures”(Chapter 2). In the beginning of this research, we tried toseek a standard for re-laying and replacing bricks. However,we came to understand that it would be more appropriateto observe the degree of deterioration and structuralcharacteristics for analysis and judge the treatment to betaken at each of the restoration sites individually. Therefore,finally, we asked Dr. Hasegawa for views on restorationprinciples which could be referred to for making thesejudgments.Chapter 3 is a discourse by Mr. Hirofumi Ikawa onrestoration of brick structures. This pertains to all fourthemes of the research and can be considered as an updateto Mr. Masaharu Nakamura’s writing in“Preservation andRestoration of Brick Cultural Properties”on chart 1. Also,this presents information on the connection between thedifferent restoration cases in Chapter 6.Chapter 4 is by Mr. Eisuke Nishikawa, who is presentlydispatched to ICCROM in Italy, on seismic protection ofbrick structures. In Italy, there are numerous brick and stonestructures that are protected as cultural properties and hepresents experiences in the country prone to earthquakeswhich has for many years faced issues in building structures.Here, the present status of Japan is taken into account inintroducing the legal framework pertaining to preservationand restoration of brick structures in Italy, approaches,methods, together with case studies. This paper provides thefundamental information necessary for Japan in consideringanti-seismic countermeasures for brick structures in thecoming future.Chapter 5 is a record of a seminar held on February 23,2017 at the Tokyo National Research Institute for CulturalProperties titled Seismic Protection Systems of HistoricMasonry Structures in Italy and Japan. First, a lecture onseismic protection of structures in Italy by Professor ClaudioModena of Padova University was given. He specializes instructural engineering and is deeply involved in the recoveryof regions in central Italy which was hit by earthquakes inAugust and October 2016. From Japan, Mr. Satoshi Nishiokawho is in charge of earthquake-proofing of historic structuresat Japan’s Agency of Cultural Affairs, gave a presentation onrecent movements in Japan. In this seminar, there was theparticipation of leading scholars and practitioners in seismichazard prevention in Japan and the two lectures werefollowed by discussions (photo).NameHirofumi IkawaYu EndoShigeru OnodaEisuke NishikawaSatoshi NishiokaNaoji HasegawaRi-ichi HanazatoOrganizationsAgency for Cultural Affairs, Cultural Properties DepartmentThe Japanese Association for Conservation of Architectural MonumentsRailway Technical Research InstituteICCROMAgency for Cultural Affairs, Cultural Properties DepartmentNational Research and Development Agency, Building Research InstituteMie University, Faculty of Engineeringchart 5 External experts at the Seminar on Preservation and Adaptive Use of Brick Masonry Structures（names listed without honorifics in Japanese alphabetical order with affiliations at that time）PhotoSeminar of "Seismic Protection of Historic Masonry Structures in Italy and Japan"9
