  The $t$-adic symmetric multiple zeta values were defined Jarossay, which have
been studied as a real analogue of $\boldsymbol{p}$-adic finite multiple zeta
values. In this paper, we consider the star analogues based on several
regularization processes of multiple zeta-star values: harmonic regularization,
shuffle regularization, and Kaneko-Yamamoto's type regularization.
  We also present the cyclic sum formula for $t$-adic symmetric multiple
zeta(-star) values, which is the counterpart of that for $\boldsymbol{p}$-adic
finite multiple zeta(-star) values obtained by Kawasaki. The proof uses our new
relationship that connects the cyclic sum formula for $t$-adic symmetric
multiple zeta-star values and that for the multiple zeta-star values.
