Trans-Neptunian Objects (TNOs) hold the pristine and critical informationnot only on the composition but also on the collisional evolution of the outer Solar System. However, information for these small and faint TNOs is still limited as observations require telescopes with large aperture and wide field of view. In this study, we use the data obtained by Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP), which is one of the deepest wide-field surveys, that utilizes the 8.2m aperture of the Subaru Telescope from 2014 to 2019. Using the pipeline for detecting moving objects developed by Chen et. al (2018), we detected 95 new TNO candidates from the three distinct fields of the HSC-SSP DEEP layer survey data, particularly, 10 candidates from COSMOS, 65 candidates from DEEP2-3, and 15 candidates from XMM- LSS. The Deep layer covers a total area of 27deg2 and observes at a depth of about mr = 25.40 in a single frame with 180s of exposure time. Finally, with continuous tracking from observations in DEEP fields from about 300 nights, we are able to place accurate orbital elements, color estimate, and lightcurve information for objects in COSMOS and XMM-LSS fields.
