Abstract: Here we report on the new medium-scale plan in Japan to construct a 30 - 50 m class millimeter (mm) and sub-mm single dish telescope. The main observing frequency of the telescope is 70 to 420 GHz, which just covers main atmospheric windows at mm and sub-mm wavelengths in good observing sites such as the ALMA site. We are also aiming at observations at higher frequency up to 1 THz with the limited use of the antenna surface, e.g., under-illumination of the telescope. One of important science goals in this new telescope project is unveiling the large scale structure (LSS) of the high-z universe and cosmic star formation history by spectroscopic surveys of high-z galaxies in CO and [CII] lines. With exploiting synergy with ALMA and possibly SPICA, this telescope can contribute to the breadth of astronomy and astrophysics, e.g., astrochemistry, star formation in the Galaxy and galaxies, cosmology, and sub-mm VLBI.
