The world’s deepest drop shaft facility for microgravity experiment, using a former coal mine shaft of 710m in depth was constructed at Kamisunagawa, Hokkaido, Japan in 1991. The rocket-shaped capsule, in which experimental devices are loaded, falls through the drop shaft and produces microgravity of approximately 1 × 10 -5 G for 10 seconds. This paper provides an outline of this drop shaft facility.
