  The Josephson effect in p-wave superconductor / diffusive normal metal /
p-wave superconductor junctions is studied theoretically. Amplitudes of
Josephson currents are several orders of magnitude larger than those in s-wave
junctions. Current-phase (J-\phi) relations in low temperatures are close to
those in ballistic junctions such as J\propto\sin(\phi/2) and J\propto\phi even
in the presence of random impurity potentials. A cooperative effect between the
midgap Andreev resonant states and the proximity effect causes such anomalous
properties and is a character of the spin-triplet superconductor junctions.
