Tono Geoscience Center (TGC) of Japan Atomic Energy Agency (JAEA) has been conducting a wide range of geoscientific research in order to build firm scientific and technological basis for geological disposal of nuclear wastes, in order to establish comprehensive techniques for the investigation, analysis and assessment of the deep geological environment in fractured crystalline rock. One of the geoscientific research programme is a Regional Hydrogeological Study (RHS) project in the Tono region, central Japan. This project started in fiscal year 1992 and main investigations finished in fiscal year 2004. After the main investigations, hydrogeological or hydrochemical long term monitoring are continued by the existing monitoring system. This document presents the results of the hydro-pressure long term monitoring from fiscal year 2005 to fiscal year 2008.
