GENERAL INFORMATION ON ISEIM 2001
Date and Venue
The 2001 International Symposium on Electrical Insulating Materials (ISEIM 2001) will be held on
November 19-22, 2001 jointly with the 2001 Asian Conference on Electrical Insulation Diagnosis and the33rd Symposium on Electrical and Electronic Insulating Materials and Applications in Systems at the
Hotel Sungarden Himeji, Himeji, Japan. The ISEIM 2001 will be sponsored by the IEEJ TCDEI and will
be technically cosponsored by the IEEE DEIS. The Chinese Electrotechnical Society (CES), the Korean
Institute of Electrical and Electronic Material Engineers (KIEEME), Kansai Section of IEEJ, IEEJ
Investigation Committee on Insulation Lifetime of Dielectric Materials and Electrical Apparatus, andHimeji Institute of Technology will be cooperative organizers.

About Himeji
A city of 460,000 people, Himeji is located in the heart of the Himeji plain in the southwestern part of
Hyogo Prefecture. Progressively amalgamating adjacent towns and villages since its municipal
inauguration in 1889, Himeji now stretches 23.5 km to the east and west 21.3 km to the north and southand boasts a total area of 273 square kilometers. Himeji is said to have been populated by human beings
for about 10,000 years, a notion supported by the discovery of ancient artifacts throughout the city. Himeji
Castle and Horyu-ji Buddhist Temple in Nara were given the World Cultural Heritage status for the firsttime in Japan, by the World Heritage Committee of UNESCO in 1993. The huge plain including Himeji
flourished over the years as an industry and transportation center in proximity to the cities of Kyoto,
Osaka and Kobe.
