The Square Kilometer Array is expected to provide the first tomographicobservations of the neutral intergalactic medium at redshifts z>6 and pinpointthe locations of individual ionized bubbles during early stages of cosmicreionization. In scenarios where star-forming galaxies provide most of theionizing photons required for cosmic reionization, one expects the firstionized bubbles to be centered on overdensities of such galaxies. Here, wemodel the properties of galaxy populations within isolated, ionized bubblesthat SKA-1 should be able to resolve at z=7-10, and explore the prospects forgalaxy counts within such structures with various upcoming near-infraredtelescopes. We find that, for the bubbles that are within reach of SKA-1tomography, the bubble volume is closely tied to the number of ionizing photonsthat have escaped from the galaxies within. In the case of galaxy-dominatedreionization, galaxies are expected to turn up above the spectroscopicdetection threshold of JWST and ELT in even the smallest resolvable bubbles atredshifts z=10 or below. The prospects of detecting galaxies within thesestructures in purely photometric surveys with Euclid, WFIRST, JWST or ELT arealso discussed. While spectroscopy is preferable towards the end ofreionization to provide a robust sample of bubble members, multiband imagingmay be a competitive option for bubbles at z~10, due to the very small numberof line-of-sight interlopers expected at similar redshifts.
