    Description
The large statistical sample of galaxies beyond z=6 explore the very
early stage of the most fundamental observables in both star formation history
and structure formation process. These observations also put critical constraints
on the cosmic reionization. I will review the current status of several high-z galaxy
surveys and future prospects.
