We present our results of selection of z>5 quasar candidates using publicly available multi-wavelength data from far-ultraviolet to far-infrared, including data from the ongoing HSC survey. We analyze the spectral energy distribution of the selected z>5 quasar candidates and discuss the evolution of their spectral shape with redshift as a result of increasing absorption by neutral hydrogen. We also present our project on the submillimeter spectroscopy of these candidates with ALMA. The research is supported by the Ministry of Science and Technology of Taiwan, grant No. MOST 103-2119-M-008-017-MY3 and MOST 105-2811-M-008-074.
