WELCOME TO HBES 2008 Dear Colleague, It is my immense pleasure to be able to announce that HBES 2008 will be held at Kyoto University, Japan, the first one outside the Western hemisphere in its history. Kyoto, a beautiful ancient city, used to be an old capital of Japan for about 1000 years since the 8th century, and has a variety of interesting and important monuments of Japanese culture. These are now registered as one of the World Heritage sites. We sincerely hope that you will enjoy a pleasant early summer stay in Kyoto along with the HBES conference. HBES- Japan has more than 100 members and all of us are eagerly waiting for your attendance in Kyoto. Certainly it is a bit far from the US and European countries, and inevitably a bit more costly than usual meetings. We shall try our best to set up fascinating scientific programmes and social gatherings to meet up the cost and more! Please contact us through e-mail if you have any questions related to the HBES 2008 in Kyoto.
