The Subaru Measurements of Images and Redshifts (SuMIRe) is the project building a new
prime-focus instruments for the 8.2m Subaru Telescope, the Hyper Suprime-Cam (HSC)
imaging camera and the massively-multiplexed fiber-fed Prime Focus Spectrograph (PFS).
These instruments offer unique opportunities in survey astronomy and cosmology. In
particular, the PFS project is based on the international collaboration including our
Brazilian collaborators. I will introduce this exciting project and the prospects for
precision cosmology, especially focused on dark energy science.
