文化財保護法と刀剣の国宝・重要文化財指定制度
The Cultural Properties Protection Law, enacted in 1950, established the government designation system for National Treasures and Important Cultural Properties covering tangible cultural properties including swords. Existing National Treasures were reclassified as Important Cultural Properties, with 181 works of especially high cultural-historical value re-designated as National Treasures, forming the institutional foundation for the public evaluation of sword value.
Description
Background of Enactment
The Cultural Properties Protection Law was enacted in 1950, partly prompted by the devastating fire that damaged the mural paintings of Horyuji's Kondo the previous year — a major setback for cultural property preservation. The law integrated and expanded on prewar legislation such as the Ancient Shrines and Temples Preservation Law and the National Treasures Preservation Law, clearly establishing a national system for designating and protecting tangible cultural properties, including Japanese swords.
Designation Categories and Reorganization
Among tangible cultural properties, swords are classified as crafts (kogeihin). Those recognized as especially important by the Minister of Education (now the Minister of Education, Culture, Sports, Science and Technology) are designated "Important Cultural Properties," and among these, works of especially high cultural-historical value from a global perspective are further designated "National Treasures" — a two-tier structure. With the law's enactment, all National Treasures previously designated under the old National Treasures Preservation Law were reclassified as Important Cultural Properties, and after renewed review, 181 works were re-designated as National Treasures.
Application to Swords
Under this system, many renowned swords have been designated Important Cultural Properties or National Treasures, giving owners certain obligations regarding preservation and public display while granting official recognition of their cultural value. A key distinction is that this is a government designation backed by legal authority, separate from the private appraisal system operated by the NBTHK (Society for Preservation of Japanese Art Swords), which issues Hozon and Juyo Token papers.
Historical Significance
The designation system under the Cultural Properties Protection Law also helped prevent the outflow and dispersal of swords overseas during the chaotic postwar period, and it continues to form the institutional backbone for the official evaluation of art and craft objects, including swords, to this day. National Treasure and Important Cultural Property designation continues to function as an evaluation benchmark in the trading, exhibition, and study of Japanese swords.
Characteristics of This Era
- Two-tier designation structure of National Treasures and Important Cultural Properties
- Blanket reclassification of former National Treasures with 181 works re-designated
- Legal government designation distinct from the NBTHK's private appraisal system
