In the paper we prove that any formally integrable Mizohata system of codimension one

1u = e1ix1 nu + f1,
2u = e2ix2 nu + f2,
...........................
n-1u = en-1ixn-1 nu + fn-1

can be reduced by a local change of the variables to a system of the form

1v1 + 2v2 = y1,
1v2 - 2v1 = y2

and, consequently, to Poisson's equation in the plane.
