The notion of a toric origami manifold, which weakens the notion of a symplectic
toric manifold, was introduced by A. Cannas da Silva, V. Guillemin and A.R. Pires. They
showed that toric origami manifolds bijectively correspond to origami templates via moment
maps, where an origami template is a collection of Delzant polytopes with some folding data.
Like a fan is associated to a Delzant polytope, a multi-fan introduced by A. Hattori and
M. Masuda can be associated to an oriented origami template. In this paper, we discuss their
relationship and show that any simply connected compact smooth 4-manifold with a smooth
action of $T^2$ can be a toric origami manifold. We also characterize products of even dimensional
spheres which can be toric origami manifolds.
