Western Gate is a stage in Tekken 5: Dark Resurrection, corresponding to Dragon's Nest in Tekken 5. The differences between this stage and its Tekken 5 counterpart are that this one is set during a thunderstorm and the area looks more ancient.
Instead of a dragon statue, several tiger statues surround the fighters and a tiger carving is placed on the ground. The bridge in the back is still there but it is no longer tied up and is on fire.
The stage BGM is titled "Garden of the Tiger".
