During excavation in the center of Kyoto (O-ike site) from 2003 to 2004, many fourlobed jars were excavated. These jars were used to stock imported urushi paint from Thailand or Cambodia from the end of the 16th to the first half of the 17th century. At the same site many traditional urushi paint tools produced in Japan during the Momoyama cultural period were also excavated. Results of elemental analysis by Py-GC/MS showed that the urushi paint was composed of Melanorrhoea usitata, Rhus vernicifera, Rhus succedanla,or their mixture. But there is no idea as to what objects,other than nambanstyle exported lacquerware,imported urushi paint was used for. Analyses of five lacquerware excavated at O-ike site showed that the urushi paint was compound of a mixture of Rhus vernicifera and Rhus succedanla. This result is material evidence that imported urushi paint was used on urushi objects in Japan.
