The target protocluster candidate was identified as a $4.5\\sigma$ overdense region of $g$-dropout galaxies, and the redshifts of $g$-dropout galaxies are determined by detecting their Ly$\\alpha$ emission. Thirteen galaxies, at least, are found to be clustering in the narrow redshift range of $\\Delta z<0.05$ at $z=3.699$. This is clear evidence of the presence of a protocluster in the target region.
