The Filmon endless sound-belt,the subject of this report,is a celluloid sound recording media manufactured in 1937 by Nihon Filmon Co.,Ltd.at what is now Komae-shi,Tokyo. The sound belt was developed in Japan to overcome the short recording time possible on SP records,which at that time was the mainstream recording media in the world. It is an extremely short-lived recording media that disappeared in about 3 years with the development of magnetic tapes for recording. Although short-lived, the sound belt made long recordings at one stretch possible,which could not be done with SP records. Thus,valuable recording of kiyomoto, nagauta and other types of Japanese music have remained. The Department of Intangible Cultural Heritage of the National Research Institute for Cultural Properties, Tokyo and The Tsubouchi Memorial Theatre Museum Waseda University have embarked on a joint study and digitization of the Filmon endless soundbelts in collections of the Institute, the Museum and other museums as well as in private collections. This report discusses the method that has made it possible to restore and to re-listen to deteriorated (hardened, deformed) or severed Filmon endless sound-belts.
