Super-Kamiokande experiment is carried out in the Mozumi mine of Kamioka Mining and Smelting Company near the village of Higashi-Mozumi, Gifu, Japan. This location has the benefit of clean water, hard rocks and 1000m overburden. The 1000m rock overburden reduces cosmic ray muons which are backgrounds for the observation to 1/100,000.


The detector lies under the peak of Mt.Ikenoyama, through a 1.8km long, horizontal mine tunnel. The research buildings and dormitory of Kamioka Observatory, Institute for Cosmic Ray Research, University of Tokyo are located in a quiet village, Higashi-Mozumi, 15minutes by car from the mine entrance.
