  We report on VLBI observations of NGC 1275 with VLBI Exploration of Radio
Astrometry (VERA) and Very Long Baseline Array (VLBA) during 2008 and 2013 at
15, 22 and 43 GHz. Our observations provide long-term variations in the radio
flux and structure of the inner jet in NGC 1275 on sub-parsec scales,
particularly at C3 which is a new radio component accountable for the recent
active state in radio regime since early-2000s. We found the apparent velocity
of C3 was $\beta_{\rm{app}} = 0.267 \pm 0.007 $, which was consistent with
typical velocities of the hot spot and/or radio lobes in the young radio
sources. Furthermore, the radio flux and size of C3 had simultaneously
increased during September 2007 and May 2012 with keeping optically-thin
spectra, suggesting that the particle acceleration occurred inside C3 as
generally seen in the hot spots of the radio lobes. Our new observations
suggest that C3 is a new-born hot spot and/or radio lobe at a very early stage
of its evolution. Our results imply the radio lobes in the radio galaxies might
be already formed on sub-parsec scales from the central SMBH and might play an
important role to produce $\rm \gamma$-ray emission in the young radio sources.
