The origin and acceleration mechanism of ultrahigh-energy cos-mic rays (UHECRs) are of the upmost importance in particle astrophysics and astronomy. The less deflection in galactic and extra-galactic magnetic fields due to their enormous kinetic energies expects a directional correlation between UHECRs and extremely energetic phenomena in the nearby universe, achieving a next-generation astronomy. The Fluorescence detector Array of Single-pixel Telescopes (FAST) is a future project for UHECR observatories, addressing the requirements for a large-area, low-cost detector suitable for measuring proper-ties of the highest energy cosmic rays with an unprecedented e?ective area. I will develop a prototype array of the FAST telescopes consisting of four 200 mm photomultiplier-tubes at the focus of a segmented mirror of 1.6 m in diameter and establish new observation method for the UHECR astronomy.
