Au Japon, les « arts performatifs folkloriques » ont connu des transformations importantes à mesure que s’est diversifiée leur gestion administrative. Aujourd’hui, ces arts reçoivent un soutien soit au titre de « patrimoine culturel folklorique immatériel », soit à celui de « ressource touristique ». Dans le premier cas, ils sont préservés et mis en valeur dans le cadre de la loi sur la protection du patrimoine culturel ; dans le second, ils entrent dans le champ de la loi relative à la promotion du tourisme, des commerces et industries régionaux. Or les principes fondateurs de ces deux lois ont généralement été considérés comme contradictoires, voire antagonistes. L’imbriquement de ces deux logiques influe pourtant sur les conditions locales de conservation des spectacles folkloriques, et, plus encore, génèrent de nouvelles formes culturelles. L’article qui suit s’intéresse à l’impact des mesures administratives sur la réinvention des spectacles folkloriques, et examine comment il est possible, en conséquence, de repenser ces derniers. In Japan the various forms of entertainment known as the folk performing arts are undergoing great change as the policies for administering them diversify. Today folk performing arts are treated within two social contexts: as traditional and regional culture to be preserved and practically managed in accordance with the provisions of the Cultural Properties Protection Law; and as tourist resources covered by the law concerning the revitalization of tourism and selected regional commerce and industry. The basic principles underlying these two laws have generally been thought to be in conflict with one another. However, the intermingling of these two social contexts not only influences the local conditions within which folk performing arts exist, but also enables the birth of new cultural forms. In this paper I will examine how folk performing arts are being re-created through the diversification of administrative processes, and consider how we can, in fact, re-imagine folk performing arts.

An AMS system (Model 4130-AMS) dedicated to ^C measurements, built by High Voltage Engineering Europe (HVEE), B.V., The Netherlands, was delivered to Nagoya University in 1996/97. Acceptance tests of its performance on carbon isotope measurements were completed in January of 1999, and routine measurements began in mid-2OOO. Since completion of the acceptance tests in early 1999, we have encountered a lot of troubles with the machine, particularly in 2002. Since the end of 2002, the machine has worked relatively well, expect for minor problems. The standard deviation (one sigma) of the ^C/^C ratio is around ±0.3% to ±0.4% (a bit larger than the uncertainty of about ±0.3% calculated from ^C counting statistics) and that of the corresponding ^C/^C ratio is ±0.03% to ±0.07%, as are tested for HOx2 targets. The number of targets measured was 330, 1430, 2077, 1003, 1,979, 1679, 1771, 1115, 1339, 866 and 1300 in each year from 1999 to 2009, respectively, and total number of target measured is 14890. Since November 1^st 2007, we had a scheduled shutdown of the AMS system, to improve the strength of the building, Furukawa Memorial Hall, against an outbreak of large scale earthquakes expected in the near future around Tokai area, central Japan. After completion of the repair, in June of 2008, we restarted ^C measurements, in encountering again similar kinds of troubles as we had experienced before. An overhaul of the AMS system was performed by an engineer from HVEE in October of 2008. In 2009, we have encountered two kinds of malfunction in generating high voltage. One was a fault of a power supply system that outputs stable DC 24V to the circuit boards for the control of high voltage of the 3MV accelerator. The other was a breakdown of a Zener diode assembly that protects damage on the control circuit system of the 3MV high voltage power supply from accidental high-voltage sparks. In both cases. we wasted away about two months to obtain the new spare parts to substitute the defective ones. However, we have measured 1300 targets in 2009, the figure bigger than the one recorded in the previous year., 第22回名古屋大学年代測定総合研究センターシンポジウム平成21(2009)年度報告
