Mizunami Underground Research Laboratory

Welcome to the MIU

Tono Geoscience Center (TGC), Japan Atomic Energy Agency (JAEA) has been carrying out a wide range of geoscientific research in order to build a firm scientific and technological basis for geological disposal.

One of the major components of the ongoing geoscientific research program is the Mizunami Underground Research Laboratory (MIU) Project in the Tono area, central Japan. Two 1,000m deep shafts and several drifts will be excavated for geoscientific research and applicability of engineering techniques will be estimated.

JAEA has been carrying out geoscientific research at two locations:
the location for investigation of crystalline rock is in Mizunami City, Gifu Prefecture;
the location for investigation of sedimentary rock is at Horonobe, Hokkaido.
