The conservation of Japanese scroll-rolls has always been performed by Japanese conservators in accordance with their traditional methods. Very few museums in Europe and USA have departments with Japanese specialists for the conservation of these objects. The National Museum of Denmark is not one of them. The authors present here a case story on which the complete conservation (dismounting and remounting) of a Japanese Kakemono has been carried out, joining the traditional materials and techniques with a modern Western methodology: the use of the low-pressure apparatus. The Japanese terminology has deliberately not been used in order to simplify the understanding of the text. -- AATA
