Data that can be retrieved from the database on traditional Japanese instruments (accessible from the website of the Department of Intangible Cultural Heritage since May) has been doubled and renewed. The database is based on information obtained through questionnaire survey on traditional Japanese instruments conducted since 2001. In addition to replies from the boards of education of the prefectures and municipalities, responses from museums throughout Japan have been included. Until now the data centered on instruments designated as cultural properties, but with this addition of data from museums, it has become possible to retrieve information about outstanding instruments and unusual instruments held by museums in various parts of Japan. Items and method for retrieval have not changed, but there are more data on instruments like shamisen, koto and tsuzumi., making formation retrieval more interesting.
