Abstract: We present the early results from the two on-going wide-field imaging survey using Subaru Telescope. Combination with the large-aperture telescope, such as Subaru, and wide-field camera, Suprime Cam, makes the deep and wide-field survey of distant galaxies realized and enable us to study galaxy formation and evolution in terms of the structure formation in enough large volume. First, we introduce the results of Suprime-Cam/UKIDSS DXS Ten-square degree (SCDXT) survey, where ∼ 10-deg2 area was deeply imaged in optical, i′ < 25.5 − 26, to match with the data taken in UKIDSS DXS and Spitzer SWIRE survey. The method to identify the aged galaxies and to measure their photometric redshift using optical-NIR colors is demonstrated, and the properties of the extremely red and bright galaxies are studied. The cluster candidates at z = 1 − 2 selected by the method is also presented. Second, we also introduce the results of the deep and wide-area narrow-band survey which covers the 1.75 deg2 at the z = 3.1 high-density region in and around SSA22 area as well as the 1.25 deg2 of the blank fields. Large overdensity of Lyα Emitters (LAE) at z = 3.1 at large scale (> 50 Mpc) is probed by the data. Properties of the LAEs in this unique region are investigated.
