Under the development of Shinkansen network Kyushu Shinkansen Line was opened in 2011. The purpose of this study is to compare the community responses to railway noise and ibration between before and after the opening of Kyushu Shinkansen Line and to compare the community response with those of the other Shinkansen Lines. Socio-acoustic surveys were carried out in areas ofKumamoto, where conventional railway and Shinkansen lines are close and arallel each other, before the opening (2008-2010) and after the opening (2011-2012). After the opening, the limited express trains were retired and more super-express trains run. Though the noise and vibration exposures were almost the same before and after the opening, the annoyances were decreased after the opening. The annoyances and daily activities caused by conventional railway noise and vibration were greater than those of Shinkansen Line.The dose-response relationship of Kyushu Shinkansen Line was lower than the other Shinakansen Lines.
