On November 22, 2014, earthquake (M[JMA]6.7) occurred in the northern part of Nagano prefecture, Japan. Although available records of ground motion indicate that the largest seismic intensities of JMA scale was 6-, more significant structure damages were concentrated in a localized area. We performed field reconnaissance and aftershock observations in order to investigate reason of the localization. In Horinouchi area where was one of the damaged areas, a site amplification of ground motions is larger than the other sites on the basis of the aftershock records. Also, some evidences of a landslide motion behind the Horinouch area was observed.
