Welcome messagernDear Colleagues and Friends,rnWelcome to the website of the 9 th Meeting of A-sian Sleep Research Society ( ASRS ) , which is scheduled to be held in Sapporo, Japan. As all of us know, ASRS is a society, which was established with the purpose of exchanging the opinion and pro-moting the cooperation in sleep research and sleep medicine among Asia countries. The first meeting of ASRS was held in Tokyo, Japan on June 16, 1994 after the formation of the Founding Committee of Asi-an Sleep Research Society ( ASRS ) in 1993. Since then, ASRS has contributed to the promotion of all aspects of sleep research by organization of scientific meetings, promotion of training and education, dis-semination of information and establishments of fel-lowships and awards. Until 8th meeting, ASRS has held meetings in various locations across Asia ( Isra-el, Thailand, China, Korea, Japan, Taiwan and India ) , and after unfortunate cancellation of 2016 meeting in Turkey we Asian sleep researchers will be able to meet again in Sapporo, Japan from 11 to 13 July this year.
