Low-luminosity AGNs (LLAGNs), a subclass of AGN, are thought to host the radiatively-inefficient accretion flow which has a relatively lower mass accretion rate. To constrain the mass accretion rate of nearby LLAGNs via spectral energy distributions, we conducted the flux survey with the Submillimeter Array (SMA). Meanwhile, the LLAGNs are critical for the future Event-Horizon Telescope (EHT) observations since its optically thin nature in mm/sub-mm is relevant for observing the black hole shadow. Thus, the flux survey of LLAGNs also serves to search the future candidate for EHT. To efficiently survey the possible candidates, the single-baseline VLBI observation utilizing the James Clerk Maxwell Telescope (JCMT) and the Greenland Telescope (GLT) is crucial for selecting the sources which are detectable with long-baseline fringes. In this talk, I will demonstrate the current status of this project and the plans.
