Japan Atomic Energy Agency (JAEA) is performing the Mizunami Underground Research Laboratory (MIU) Project, which is a scientific study of the deep geological environment as a basis of research and development for geological disposal of high level radioactive wastes (HLW), in order to establish comprehensive techniques for the investigation, analysis and assessment of the deep geological environment in the crystalline rock. The MIU Project has three overlapping phases, Surface-based investigation phase (Phase I), Construction phase (Phase II), and Operation phase (Phase III). This report compiles the data of results from borehole investigations which has been carried out in the research gallery in the fiscal year from 2012 to 2014. These data include results of core observation, geophysical logging, and so on.
