Folgender Text von hier fasst die Unterschiede/Gemeinsamkeiten ganz gut zusammen:

Soon after building the magnum opus of Forbidden Eye, Tokyo Disneyland requested an Indiana Jones adventure for Japanese fans to enjoy at their newest park, Tokyo DisneySea. Baxter and his team outdid themselves again with Indiana Jones and the Crystal Skull, a thrill-filled ride with the same track as Forbidden Eye, but with a slightly different storyline and with unique special effects. Even the feel of the ride is somewhat distinct.
"The Disneyland ride in California is run hydraulically, whereas in Tokyo the ride is electronic," Baxter explains. "So, there is a difference in the ride feel -- the Disneyland ride has a little more pillowy quality, and the Tokyo ride is more of a sharp quality to the electronic motion there."

The storyline itself was also altered to reflect the Tokyo fans' interests in other cultures. While the Temple of the Forbidden Eye has a plot revolving around Indian culture, the ride in Tokyo features elements from Aztec culture. While both rides do follow the same track of the scenery and characterizations, some of the special effects visitors may encounter are very different.

"The reason we did an Indy ride over there was because everyone already believed it to be a spectacular attraction, so there wasn't too much that needed to be changed except for a few of the special effects," Baxter recalls. "We had a great effect when we opened where Mara threw a light towards the ceiling and a big crashing amount of rockwork came out of the ceiling and smashed right in front of the car. And it was terrific! But we just couldn't keep it going. So that effect was eliminated early on.

"The differences often revolved around building codes," Baxter continues. "For instance, fire, which is a key part of the Disneyland ride, is illegal to have indoors in a ride in Japan, so we had to come up with a new effect. We ended up using this huge, amazing vortex that looks like a tornado right smack dab in the middle of the big scene with Mara. It's very effective in its own right, but there was a lot of commitment to do something spectacular as the fire at Disneyland. A lot of effort went in to insure the Tokyo project had an equivalently amazing effect."
