Dear colleagues and Friends,
 On behalf of the Organizing Committee of the 14th IRS and the 30th ISIAN, I would like to extend a warm and cordial welcome to everyone who comes to Tokyo to attend this combined Rhinological congress 2011.
 I am proud to welcome the most distinguished experts in this field from all over the world. I anticipate that this Congress will be intense, rich in content, and filled with the highest level of scientific information and discussion.
 The program, which ranges from basic research to clinical studies of such topics as rhinosinusitis, allergy of the nose, immunology, infection, olfaction, rhinoplasty, skull base surgery, tumors and sleep medicine, will be of high quality, in order to reflect the remarkable recent progress in the field.
 I am looking forward to your participation in the Congress, and your great contributions to this international scientific event are very much appreciated. I am sure that your participation will make the Congress fruitful and valuable.
 Tokyo is recognized as one of the worlds’ most exciting and fascinating cities with rich culture and history, fashionable shops, excellent food, and great activities.
 I am convinced that the well-known Japanese hospitality will satisfy you and that this Congress will be memorable and successful. I wish you all spend a very enjoyable time in Tokyo and Japan.
 Sincerely,

 Dear Colleagues,

 As we had advertised, IRS/ISIAN 2011 was scheduled to be held in Tokyo, Japan from April 6 to 9, 2011. However, the congress has been officially postponed on ground of the tragedy and aftermath caused by “ the Great East Japan Earthquake”.
 The whole Japanese nation commits to reconstruction from the tremondous disaster.
 The risk of radioactive contamination caused by the nuclear power plant accident in Fukushima is gradually improving.
 On the basis of above conditions, we have decided the new schedule of IRS/ISIAN 2011 from September 20 to 23, 2011. It is highly appreciated if you all actively participate in the newly scheduled IRS/ISIAN 2011.
 We believe that the meeting will provide participants with both a forum for active scientific exchange and an opportunity to promote future scientific cooperation and friendship. Your involvement would certainly contribute to the overall success of the events. We are doing our best to successfully hold IRS/ISIAN 2011 in September.
 We look forward to your presence in this occasion.

 Sincerely yours,
