abstract = "We present the current status of the University of Tokyo Atacama 1.0-m telescope constructed at the summit of Co. Chajnantor (5,640 m) in Atacama, Chile, which is an optical/infrared telescope at the world's highest site. The telescope is an f/12 Ritchey-Chretien type with a field of view of 10 arcmin. It is installed in a 6-m dome and is controlled from the operation room in a container separated from the dome. The engineering first light observation was carried out in March 2009, and the astronomical observations have been carried out since June 2009. The pointing of the telescope is as accurate as 2.4 arcsec (RMS), showing good tracking accuracy of 0.2 arcsec for 60-s observation without guiding. The Hartmann constant is 0.19 arcsec and the image quality of the telescope is satisfactory for scientific observations. The best PSF obtained is 0.5 arcsec (FWHM) in optical, which demonstrates that the summit of Co. Chajnantor is one of the best seeing site in the world. Also the excellent atmospheric transmission in infrared wavelength at the site is proved by successful observations carried out by the ANIR near-infrared camera and the MAX38 mid-infrared instrument. In the near future, the operation room will be connected to the base support facility at San Pedro de Atacama for remote observation.",
