We are conducting ultra-deep multi-narrowband imaging observations in COSMOS called CHORUS (Cosmic HydrOgen Reionization Unveiled with Subaru) with Hyper Suprime-Cam on Subaru. I will present an overview of the scientific goals of CHORUS, a report of the current status of the observations, and how to access these data.
