To find the value of \( a \) for the point \( (a, 2) \) that lies on the logarithmic equation \( y = \log_3 x \), we substitute \( y = 2 \) into the equation:

\[
2 = \log_3 a
\]

To solve for \( a \), we can rewrite the logarithmic equation in its exponential form:

\[
a = 3^2
\]

Calculating \( 3^2 \):

\[
a = 9
\]

Thus, the value of \( a \) is

\[
\boxed{9}
\]
