It is known that any hypersurface in an almost complex space admits an almost contact manifold[11, 14]. In this article we show that a hyperplane in an almost contact manifold has an almost complex structure. Along with this result, we explain how to determine when an almost contact structure induces a contact structure, followed by examples of a manifold with a closed G2-structure.
