We suggest a simple model which produces the suitable fermion mass hierarchies and flavor mixing angles based on the 6-dimensional N = 1 supersymmetric SO(10) grand unified theory compactified on a T2/(Z2 × Z2′) orbifold. We introduce 6D and 5D matter fields, which contain the ist and 2nd generation marter fields as the zero modes, respectively. The 3rd generation marter fields are localized on a 4D brane. The Yukawa couplings for bulk fields are suppressed by volume factors from extra dimensions. The suitable fermion mass hierarchies and flavor mixings are generated by these volume suppression factors.
