Supermassive black holes observed at high redshift $z\gtrsim6$ could growfrom direct collapse black holes (DCBHs) with mass $\sim10^5\,M_{\odot}$, whichresult from the collapse of supermassive stars (SMSs). If a relativistic jet islaunched from a DCBH, it can break out of the collapsing SMS and produce agamma-ray burst (GRB). Although most of the GRB jets are off-axis from our lineof sight, we show that the energy injected from the jet into a cocoon is huge$\sim10^{55-56}\,{\rm{erg}}$, so that the cocoon fireball is observed asultra-luminous supernovae of $\sim10^{45-46}\rm{\,erg\,s^{-1}}$ for $\sim5000[(1+z)/16] \rm{\,days}$. They are detectable by the future telescopes with nearinfrared bands, such as, $Euclid$, $WFIRST$, $WISH$, and $JWST$ up to $z\sim20$and $\sim 100$ events per year, providing a direct evidence of the DCBHscenario.

Jet-powered supernovae of $\sim 10^5\,M_{\odot}$ population III stars are observable by $Euclid$, $WFIRST$, $WISH$, and $JWST$
