Submillimeter (submm) and millimeter (mm) follow-up observations have played an essential role in identifying gamma-ray burst (GRB) afterglow and host galaxies in, for example delineating the energy scale, geometry, radiation physics, and environments of long GRBs. However, submm/mm follow-up observations have lagged behind X-ray, optical and cm radio observations (summaries of afterglow observations are available in Urata et al. 2015) because of the limited sensitivity of previous submm/mm facilities coupled with the higher redshift of Swift GRBs. To break this situation, we have been managing multi-wavelength afterglow follow-ups by using SMA, ALMA and JCMT. In this paper, we summarize these results and discuss further follow-up studies.
