We have performed GPS campaign observations at Jododaira, Tateyama Mountains, Northern Alps, central Japan, since 1996. From the result of 10 years of observations, we detected remarkable crustal movement around the Tateyama Mountains. Jododaira station has moved toward WSW at 4.2±0.4mm/yr and uplifted at 3.8±0.6mm/yr during the period form 1996 to 2004, with respect to the GEONET Toyama station that is assumed as fixed. The acceleration of horizontal movement at Jododaira station started from 2000-2001. A possible reason of the acceleration is the effect of slow slip event on the Tokai subduction zone, which started from 2000.
