A spacecraft "Hayabusa" revealed that an asteroid "Itokawa" was a rubble-pile asteroid. The shape and surface regoloith distribution of this asteroid was unique. This research purpose is to bring out the formational process of the asteroid. I think Brazil nut efect holds the key to the resolution. I conducted experiment on the ground and discuss the effects on grain properties and shaking properties. I ran simulation and compare the simulation results with experimental ones. I also discuss whether the model is reasonable.
