  The mass of the axion and its decay rate are known to depend only on the
scale of Peccei-Quinn symmetry breaking, which is constrained by astrophysics
and cosmology to be between $10^9$ and $10^{12}$ GeV. We propose a new
mechanism such that this effective scale is preserved and yet the fundamental
breaking scale of $U(1)_{PQ}$ is very small (a kind of inverse seesaw) in the
context of large extra dimensions with an anomalous U(1) gauge symmetry in our
brane. Unlike any other (invisible) axion model, there are now possible
collider signatures in this scenario.
