      Dear Colleagues: 
      We cordially invite you to join the joint conference of the Asian 
      Crystallographic Association (AsCA) and the Crystallographic Society of 
      Japan (CrSJ) in Tsukuba, Japan, from November 20th to 
      23rd, 2006.  This conference is the seventh conference 
      counting from the inaugural conference in Singapore in 1992 and follows 
      the highly successful AsCA’04 conference in Hong Kong. It includes all 
      aspects of materials science related to crystallography, such as nano and 
      biological materials, and encompasses X-ray and neutron 
      scattering/diffraction, electron microscopy, XAFS, NMR and so on. Crystal 
      growth studies are also welcomed at the conference. 
      Tsukuba, in the shadow of Mt. Tsukuba, is
      located about 50km northeast of Tokyo and
      about 40km northwest of the New Tokyo International
      Airport in Narita. Tsukuba, formerly farming
      land, was established as a science city about
      35 years ago, and following the International
      Exposition of Science and Technology (Tsukuba
      EXPO ’85) became well known not just in
      Japan, but internationally. It has grown
      to become an international-level research
      center, with 2 universities and more than
      40 research laboratories. A new rail link
      from Akihabara (Tokyo) to Tsukuba (45 minutes)
      will open in summer 2005.  
      We look forward to meeting you at AsCA’06/CrSJ, which will provide you 
      with an outstanding variety of multi-disciplinary science and a great 
      forum to interact with international colleagues in vibrant 
environment. 
      Professor Kazumasa Ohsumi 
      Chairman
