We propose to conduct the first phase of a comprehensive survey of the outer Solar System beyond Jupiter. This first phase will consist of two sciences. The first science is an investigation of the physical properties of the Jupiter Trojans (JTs) and Hilda asteroids, in particular the spin rate and color distributions of these objects. The another science is a measurement of the size-frequency distribution of faint Trans-Neptunian Objects (TNOs) (25.5 < r < 27.0). We will implement the observations as a series of high cadence (30 minutes) images covering five Subaru/HSC fields in the JT L4 and L5 clouds. These images will be used to generate light curves of the JTs and Hildas which are in the fields, and to detect faint TNOs by using a shift-and-stack photometric analysis. Color information for the JTs and Hildas will be obtained by making the light curve measurements in different filter bands. These measurements will help constrain models of the formation and evolution of the outer Solar System, in particular the origin of the JTs and Hildas, the migration of the giant planets in the early Solar System, and the history of collisional erosion of the TNOs during this migration.
