This is Tokyo DisneySea's Lost River Delta. Like the Arabian Coast area, it sits on the other side of the DisneySea waterway, so it is accessed by crossing over one of several bridges. The Indiana Jones Adventure: Temple of the Crystal Skull, is housed in an ancient Mayan Temple (as an interesting side note....the attraction was given that title in 2001, seven years before the last Indy movie was released). The Indiana Jones attraction in Tokyo DisneySea is similar to the Anaheim version (same track layout), but Tokyo's has a Mayan theme inside and out. Also, Tokyo's has a much larger exterior, a better queue, better effects, some better scenes (they've replaced the fake looking "projected rats on a projected beam" scene with something much better), AND they take your picture at the end of the attraction as the vehicle dips down under the giant rolling boulder.
Next door to Indy is Raging Spirits, a roller coaster ride through an archaeological excavation site. This attraction has a 360 degree vertical loop and uses some fire effects which are pretty impressive when riding at night.
Notice in the photo above and below how the steps are on fire even with water running over them.
