The ‘Research and Reports on Intangible Cultural Heritage’ volume 4 was issued in March 2010. This year volume includes the three reports which relate directly to the Convention for the Safeguarding of the Intangible Cultural Heritage: “Convention for the Safeguarding of the Intangible Cultural Heritage Now in Its Implementation Phase” by Mr. Miyata Shigeyuki, “Intangible Cultural Heritage in the Asia-Pacific Region, Classification of Items Listed on the Representative Lists and the Function of Specialized Institutions” by Ms. Matsuyama Naoko, and “Challenges of Safeguarding Intangible Cultural Heritage – Visiting various regions in Japan and Asia-Pacific countries” by Mr. Hoshino Hiroshi. The Convention for the Safeguarding of the Intangible Cultural Heritage went into effect on April 20, 2006. The understanding and handling of cultural heritage vary depending on the countries that ratified the convention because of the circumstances of each country, and so this situation is fraught with versatile and complicated issues. The reports show a portion of these circumstances. As with the previous volumes, the PDF version of all pages will be made public on our website.
